Free physical therapist assistant interview questions for clinic owners without HR: 6 sets on scope, supervision, safety, and settings, plus a scorecard.
Six question sets for the employer side of the table: core treatment, scope and supervision, patient handling, five practice settings, behavioral evidence, and a 1-to-5 scorecard with a verification checklist. Download as DOCX.
Most interview-question lists for this role are written for the candidate, not for you. They teach a new graduate how to answer, which is useful to them and close to useless to a clinic owner who has an open schedule, a supervising therapist stretched thin, and one hour to decide whether the person across the table is safe to put in front of patients. This page is the other side of the table.
At FirstHR, we build for small employers who hire without an HR department, and a physical therapy practice is one of the clearest cases. Here are six question sets for a physical therapist assistant hire, each question paired with why it is worth asking and what a strong answer sounds like, plus a scorecard so the decision rests on written evidence.
One of these sets matters more than the rest. A PTA works under the direction and supervision of a physical therapist, and a candidate who is unclear about where that line sits is a regulatory exposure for the practice that employs them. That set is second on this page for a reason.
TL;DR
Interview a physical therapist assistant on six things: treatment delivery inside a plan of care, scope and supervision, patient handling and safety, fit with your practice setting, behavioral evidence, and escalation judgment. Ask what stays with the physical therapist and what would make the candidate stop a session and call the same day. Score every candidate on the same 1-to-5 rubric, then verify the license on the state board site before the offer.
What to Assess in a PTA
Assess six things: whether the candidate can carry a plan of care forward with judgment, whether they know the scope line, whether they escalate, whether they handle patients safely, whether their experience matches your setting, and whether their examples are real. Scope and escalation come first, because the rest can be coached and those two cannot.
The role is different enough from a physical therapist hire that the questions should not be borrowed. You are not testing whether the candidate can evaluate a patient, since that is not their job. You are testing whether they can execute someone else's plan well, notice when the patient stops fitting it, and say so to the right person on the same day.
Clinical signals
Checks precautions before starting a session
Progresses on patient response, not the calendar
Records numbers, not impressions
Scope discipline
States plainly what stays with the PT
Knows supervision rules vary by state and payer
Raises a disagreement instead of changing the plan
Safety habits
Controls a fall rather than fighting it
Has a real threshold for asking for help
Reports incidents and says what changed after
Red flags
Claims to evaluate or discharge independently
Cannot name a reason to call the PT the same day
Comfortable documenting what did not happen
The most useful follow-up on this page is some version of tell me about a specific patient. Candidates who have done the work reach for a person; candidates who have mostly read about it reach for a principle.
The Scope Line, and Why It Is Your First Question
The physical therapist owns the initial examination, the evaluation, the plan of care, re-evaluation, and discharge. The physical therapist assistant delivers the interventions inside that plan, collects objective data, and reports back. That division is the whole reason the credential exists, and it is the first thing to test.
Ask it plainly and listen for hedging. A candidate who says they have written plans of care, performed evaluations, or discharged patients on their own is describing how they will practice in your clinic, whether or not they realize what they just said. A strong candidate names the PT responsibilities without prompting and adds that the specifics vary by state, which tells you they check rather than assume.
Responsibility
Physical Therapist
PTA
Initial examination and evaluation
Writes and changes the plan of care
Re-evaluation and progress determination
Discharge decision
Delivers interventions in the plan
Collects objective data and documents the visit
The supervision requirement itself is set by your state practice act and by the payer, and it is narrower than most candidates assume. Whether the supervising PT must be on the premises or simply reachable, and how often the PT must see the patient, changes by state and by setting. Ask what arrangement the candidate has worked under rather than assuming their last job matches yours.
Which Question Set to Use
Use the core treatment set and the scope and supervision set with every candidate, no exceptions. Add the safety set, the block that matches your practice setting, and the behavioral set, then score everyone on the same rubric. The guide below shows what each set covers.
Core Treatment Questions
Can they treat?
Carrying a plan of care forward, progressing inside it, reading a patient response, teaching a home program, and taking real measurements. Ask this set of everyone.
Scope and Supervision
The set most lists skip
What stays with the physical therapist, what supervision the candidate has worked under, and what makes them stop and call. The compliance heart of the role.
Patient Handling and Safety
Transfers and falls
Transfers with weight-bearing restrictions, guarding a fall, when to ask for a second person, incident reporting, and the compliant way to ask about physical demands.
Setting-Specific
Five practice settings
Separate blocks for outpatient orthopedics, skilled nursing, home health, pediatrics, and acute care, because the same license is practiced very differently.
Behavioral and Situational
Evidence, not principles
Plateaus, hard conversations, disagreements with a supervising therapist, heavy caseloads, and being asked to do something outside scope. Real situations.
Scorecard and Red Flags
Score, do not guess
A 1-to-5 rubric across seven areas, a PTA-specific red-flag list, and a pre-hire verification checklist for license, accreditation, and references.
Match the Sets to Your Setting
Outpatient orthopedics: core, scope, safety, the outpatient block, behavioral. Skilled nursing: add the productivity and documentation-honesty questions and weigh them heavily. Home health: weight safety, autonomy, and how the candidate reaches the supervising PT from the field. Pediatrics or school-based: weight engagement and working with parents and teachers. Acute care: weight lines, precautions, and stop criteria. Every setting keeps the scope and supervision set whole. You can find more hiring kits in the hiring templates library.

Set 1: Core Physical Therapist Assistant Questions
Carrying a plan of care forward, progressing inside it, responding to new pain, taking real measurements, and teaching a home program a patient will actually do. Ask this set of everyone.
Ask this set of every PTA candidate, in every setting. It tells you whether the
person can carry a plan of care forward and read a patient in front of them,
rather than run a list of exercises off a sheet.
QUESTIONS TO ASK
1. A plan of care lands on your schedule for a patient you have never met.
Walk me through the first ten minutes of that session.
Why ask it: this is the PTA job in miniature, and it shows whether the
candidate reads the plan before touching the patient.
Strong answer: reads the evaluation and the goals, checks precautions and
weight-bearing status, confirms with the patient how they have been since
the last visit, then starts the interventions the PT selected.
Weak answer: goes straight to the exercise list without checking
precautions or asking the patient anything.
2. How do you decide how much to progress an exercise inside a plan of care?
Why ask it: progression is the daily judgment call a PTA actually makes,
and it sits right next to the scope line.
Strong answer: works within the parameters the PT set, uses objective
response (form breakdown, reps to fatigue, symptom behavior) to move within
that range, and calls the PT when the patient needs something outside it.
Weak answer: progresses on a fixed weekly schedule, or changes the plan on
their own because the patient looked ready.
3. What do you do when a patient reports new pain during an exercise?
Why ask it: it is the most common in-session decision and a direct safety
signal.
Strong answer: stops the movement, asks what the pain is and where, screens
for anything that does not fit the diagnosis, modifies within the plan, and
documents it. Escalates to the supervising PT when the change is new or
unexplained.
Weak answer: tells the patient to push through, or stops the session
entirely with no communication to the PT.
4. Which objective measures do you take, and how do you record them?
Why ask it: the PTA collects most of the data the PT re-evaluates against,
so sloppy measurement quietly corrupts the whole plan.
Strong answer: names specific measures used in your setting, takes them the
same way each time, and records the number rather than an impression.
Weak answer: describes progress only as better or worse.
5. How do you teach a home exercise program to a patient who is not going to
do it?
Why ask it: adherence is where outcomes are won or lost, and the PTA has
more contact time with the patient than the PT does.
Strong answer: cuts the program down to what the patient will actually do,
ties it to something they care about, demonstrates and watches them do it
back, and follows up next visit.
Weak answer: hands over a printed sheet and moves on.
6. Which modalities and equipment have you used, and for what?
Why ask it: it separates real hands-on experience from coursework.
Strong answer: specific equipment, specific indications, and honesty about
what they have not used.
Weak answer: claims broad experience with everything and cannot give a
patient example for any of it.
7. Tell me about a patient you worked with from the first visit to discharge.
What changed?
Why ask it: it turns everything above into evidence.
Strong answer: a real patient, the starting limitation, what the candidate
personally did, and a measured result.
Weak answer: a general description of a caseload with no individual detail.
NOTES
[Capture the specific patients, measures, and equipment named, and any gaps.]
Set 2: Scope, Supervision, and Escalation Questions
What stays with the physical therapist, what supervision the candidate has worked under, what makes them stop and call the same day, and what goes in their note. The set generic lists skip.
Scope, Supervision, and Escalation Questions
PHYSICAL THERAPIST ASSISTANT INTERVIEW: SCOPE AND SUPERVISION
Candidate: __
Interviewer: __
Date: __
This is the set that matters most and the one generic question lists skip. A
PTA works under the direction and supervision of a physical therapist, and the
line between what they may and may not do is set by your state practice act and
by the payer. A candidate who is fuzzy here is a compliance problem, not just a
clinical one.
QUESTIONS TO ASK
1. What can a PTA do, and what stays with the physical therapist?
Why ask it: it is the single most revealing question in the interview.
Strong answer: the PT owns the initial examination, the evaluation, the
plan of care, re-evaluation, and discharge. The PTA carries out the
interventions in that plan and reports back. The candidate states this
plainly and adds that the details vary by state.
Weak answer: treats the line as a formality, or claims to have written
plans of care and discharged patients independently.
2. What kind of supervision have you worked under, and how close was the PT?
Why ask it: supervision requirements differ by state and by setting, and
you need to know what the candidate is used to.
Strong answer: describes the actual arrangement, knows whether the PT had
to be on the premises or reachable, and knows that the requirement is set
by the state and by the payer rather than by the clinic.
Weak answer: has never thought about it, or describes working alone in a
way that would not meet a supervision rule.
3. What would make you stop a session and call the supervising PT the same
day, rather than mention it at the next visit?
Why ask it: escalation judgment is the safety valve on the whole model.
Strong answer: names concrete triggers such as a significant unexplained
change in symptoms, a new neurological complaint, chest pain or shortness
of breath, a fall, signs of infection, or a patient who no longer matches
the plan. Says they would call, not text and hope.
Weak answer: cannot name a trigger, or would wait until the next
scheduled PT visit no matter what.
4. How do you handle it when you disagree with the plan of care?
Why ask it: it tests both judgment and scope discipline at the same time.
Strong answer: raises it with the PT with the specific observation behind
it, then follows the plan or the revised plan. Does not change it alone.
Weak answer: either silently modifies the plan, or never questions
anything at all.
5. A patient asks you what their diagnosis means and whether they will be
able to return to work. How do you answer?
Why ask it: patients ask the person they see most, and the honest answer
requires knowing where the PTA role ends.
Strong answer: explains what they can from the plan, is straight about
what only the PT or the physician can answer, and gets the question in
front of the right person rather than guessing.
Weak answer: gives a prognosis on the spot.
6. What is the difference between a PTA and a physical therapy aide?
Why ask it: it confirms the candidate knows their own credential is a
licensed one and understands what an aide may not do.
Strong answer: the PTA is licensed or certified, educated in an
accredited program, and may deliver skilled interventions under the PT.
An aide is unlicensed support and may not perform skilled treatment.
Weak answer: describes the two as roughly the same job.
7. How do you document, and what goes in your note versus the PT note?
Why ask it: documentation is where scope becomes an audit trail.
Strong answer: writes the treatment note for the visits they deliver,
records objective data, and leaves the re-evaluation and the progress
determination to the PT.
Weak answer: has signed documents that should carry a PT signature.
NOTES
[Record exactly what the candidate believes they may do without the PT.]

Set 3: Patient Handling, Transfers, and Safety Questions
Transfers with weight-bearing restrictions, controlling a fall during gait training, the threshold for asking for a second person, incident reporting, and the compliant way to ask about the physical demands of the job.
Patient Handling, Transfers, and Safety Questions
PHYSICAL THERAPIST ASSISTANT INTERVIEW: PATIENT HANDLING AND SAFETY
Candidate: __
Interviewer: __
Date: __
PTAs do most of the hands-on transfer and gait work, which is where injuries to
patients and to staff happen. Ask about the essential functions of the job and
how the candidate performs them. Do not ask about the candidate's health,
disabilities, or medical history.
QUESTIONS TO ASK
1. Walk me through a transfer from bed to chair with a patient who has partial
weight-bearing restrictions.
Why ask it: it is a concrete safety task and the answer is hard to fake.
Strong answer: confirms the restriction and the order, sets up the space
and the equipment, explains the sequence to the patient, uses a gait belt
and correct body mechanics, and knows when a second person is required.
Weak answer: describes the transfer with no setup, no belt, and no plan
for what happens if the patient loses the leg.
2. What do you do when a patient starts to fall during gait training?
Why ask it: it tests trained reflex rather than opinion.
Strong answer: controls the descent rather than fighting the fall, protects
the patient's head, does not try to hold the patient up at the cost of
both of them going down, then assesses, reports, and documents.
Weak answer: describes catching the patient, or skips the reporting step.
3. When do you ask for a second person or a mechanical lift?
Why ask it: the candidate's threshold here is a direct predictor of injury
risk on your team.
Strong answer: has a clear threshold based on the patient rather than
pride, and says they have asked for help before.
Weak answer: never needs help.
4. Tell me about a safety incident you were involved in or witnessed. What did
you do and what was reported?
Why ask it: incident behavior is the honest test, and reporting culture is
what you are actually hiring into.
Strong answer: a specific event, immediate patient care first, then the
report, then what changed afterward.
Weak answer: has never seen one, or reports nothing.
5. How do you handle infection control between patients in a busy gym?
Why ask it: it is routine, visible, and often the first thing that slips
under productivity pressure.
Strong answer: specific and unglamorous: hand hygiene, equipment cleaning
between patients, and knowing your setting's precautions.
Weak answer: vague.
6. This role requires assisting patients with transfers and mobility, which
includes lifting and supporting adult body weight, standing for most of a
shift, and helping patients to the floor and back. Can you perform these
essential functions, with or without a reasonable accommodation?
Why ask it: this is the compliant way to reach the physical demands of the
job. Write the essential functions into the posting first, then ask this
question the same way of every candidate.
Strong answer: a direct yes, or a specific accommodation request you can
then discuss.
Note: do not ask about back problems, injuries, medical history, workers
compensation claims, or disabilities. Under the ADA those are pre-offer
disability-related inquiries.
NOTES
[Note the transfer sequence described and the threshold for asking for help.]
Set 4: Setting-Specific Questions
Separate blocks for outpatient orthopedics, skilled nursing, home health, pediatrics, and acute care. Ask the block that matches your practice, and the candidate's current block too if they are switching.
Setting-Specific Questions (Outpatient, SNF, Home Health, Peds, Acute)
Plateaus, hard conversations with patients, disagreements with a supervising therapist, heavy caseloads, and being asked to do something outside scope. Evaluate with the STAR pattern.
Behavioral and Situational Questions
PHYSICAL THERAPIST ASSISTANT INTERVIEW: BEHAVIORAL AND SITUATIONAL
Candidate: __
Interviewer: __
Date: __
Past behavior predicts future behavior better than stated intentions. Use the
STAR pattern to evaluate: a real Situation and Task, the specific Action the
candidate took, and a measurable Result.
QUESTIONS TO ASK
1. Tell me about a patient who was not making progress. What did you do?
Why ask it: the plateau is the most common real problem in a caseload.
Strong answer: noticed it in the objective data, raised it with the PT with
that data, and adjusted once the PT changed the plan.
Weak answer: added exercises, or blamed the patient.
2. Describe a time you had to tell a patient something they did not want to
hear.
Why ask it: PTAs have the most contact time and take the most pushback.
Strong answer: direct, kind, and specific, with the reason attached.
Weak answer: avoided the conversation or handed it to the PT to deliver.
3. Tell me about a disagreement with a supervising therapist or a nurse. How
did it end?
Why ask it: it tests whether the candidate can raise something without
either going silent or going around the person.
Strong answer: raised it directly with the observation behind it, accepted
the decision, and the working relationship survived.
Weak answer: a story where everyone else was wrong.
4. Describe your heaviest caseload. How did you keep quality up?
Why ask it: productivity pressure is the real working condition of the job
and you want to know what breaks first under it.
Strong answer: concrete habits (documenting between patients, prepping the
space, triaging what each patient most needs that day) and an honest
account of what suffered.
Weak answer: claims nothing ever suffered.
5. Tell me about a time you were asked to do something you were not
comfortable doing.
Why ask it: for a PTA this is usually a scope question wearing everyday
clothes.
Strong answer: says what it was, why they were not comfortable, and how
they raised it. This is the answer you want to hear from someone who will
be alone with a patient.
Weak answer: has never had one, or complied without saying anything.
6. Why this setting, and why our practice?
Why ask it: retention. A PTA who wants outpatient sports and is taking a
subacute job to get started will leave, and it is better to know now.
Strong answer: specific about the setting and the patient population.
Weak answer: any job will do.
7. What do you want to be doing in three years?
Why ask it: many PTAs are considering PT school, which is not a problem but
is a planning fact.
Strong answer: honest, whatever the answer is.
Weak answer: an answer that is obviously tailored to what you want to hear.
NOTES
[Capture the Situation, Action, and Result for each answer.]

[ ] Any required background check completed under applicable rules
A strong answer is specific, sequenced, and honest about limits. A weak answer is a principle with no patient attached. The three questions below carry the most weight in a PTA interview, so here is what each sounds like at both ends.
What can a PTA do, and what stays with the physical therapist?
Strong answer: The physical therapist owns the initial examination, the evaluation, the plan of care, re-evaluation, and discharge. The PTA delivers the interventions in that plan, collects objective data, and reports back. A strong candidate states this without hedging and adds that the specifics are set by the state practice act, so they check when they move.
Weak answer: A weak answer treats the line as paperwork, or describes writing plans of care and discharging patients independently. That is the answer that should end the interview.
What would make you stop a session and call the PT the same day?
Strong answer: Names concrete triggers: a significant unexplained change in symptoms, a new neurological complaint, chest pain or shortness of breath, a fall, signs of infection, or a patient who no longer matches the plan. Says they would call the PT rather than leave a message and continue.
Weak answer: A weak answer cannot name a single trigger, or would wait for the next scheduled PT visit no matter what happened.
Walk me through a transfer with partial weight-bearing restrictions.
Strong answer: Confirms the restriction and the order first, clears and sets up the space, explains the sequence to the patient, uses a gait belt and correct body mechanics, and states when a second person or a lift is required. The setup is most of the answer.
Weak answer: A weak answer starts at the lift itself, with no confirmation of the restriction, no belt, and no plan for the patient losing the leg mid-transfer.
Notice the pattern: in each case the strong answer front-loads the setup, the check, or the escalation, and the weak answer starts at the action. That is the difference you are listening for across the whole hour.
Supervision and Billing Questions Owners Forget
Hiring a PTA changes what your practice can bill, and most owners find that out after the offer rather than before it. If you treat Medicare Part B outpatient patients, the payment rate for a service furnished by a PTA is not the same as for the same service furnished by the physical therapist.
PTA Services Bill at 85 Percent Under Medicare Part B
Outpatient therapy services furnished in whole or in part by a physical therapist assistant are billed with the CQ modifier and paid at 85 percent of the otherwise applicable Part B amount, effective January 1, 2022. The modifier applies when the PTA furnishes more than 10 percent of the minutes of a service, the de minimis standard (Centers for Medicare and Medicaid Services). Commercial payer rules vary.
This is a reason to model your staffing mix, not a reason to avoid the hire. The wage gap between a PTA and a physical therapist is far wider than the payment adjustment, which is why the role exists in the first place. What it does mean is that the interview should establish exactly which services the candidate is comfortable delivering, because that mix is what your billing will look like.
It also raises a question worth asking directly: how does the candidate handle documentation when productivity expectations and honest minutes pull in different directions? An answer that hedges here is the most expensive kind of red flag a practice can hire.
License and Credential Verification
Verify the license yourself on the state board site before the offer, and save the date and the result. Every state licenses or certifies physical therapist assistants, and the credential normally requires graduation from an accredited PTA program plus a passing score on the national examination for the role.
Verify the license yourself
Look the candidate up on your state board site rather than accepting a copy of a card. Save the date of the lookup and the result, because the question later is whether you checked.
Confirm the program
Confirm graduation from an accredited PTA program. It is the education requirement behind the credential in every state, and it is quick to verify.
Search the exclusion list
If you bill any federal program, search the federal exclusion list before hire and keep the dated result. Employing an excluded person carries its own penalty.
Call a supervising PT
Ask a reference who actually supervised the candidate about scope judgment and escalation specifically, not just about attitude and attendance.
Verification is a records task as much as a compliance one. Keep the license lookup, the dated search of the federal exclusions list, and the reference notes in the employee file, because a year from now the question will be whether you checked and a memory of checking is not an answer. If you run a background check, follow the applicable rules for notice and consent. This is general information, not legal advice.
Physical Therapist Assistant Pay
Use the federal survey as the anchor, then adjust for your market, setting, and schedule. The national median gives you a defensible starting point and a range to place a specific candidate inside, which matters when a strong applicant has two offers.
Median $68,380 a Year (BLS OEWS, May 2025)
Physical therapist assistants had a median annual wage of $68,380, about $32.88 an hour. The lowest ten percent earned under $47,750 and the highest ten percent above $89,510, with the twenty-fifth percentile at $59,820 and the seventy-fifth at $78,680 (Bureau of Labor Statistics). Physical therapy aides, an unlicensed role, sat at a median of $35,240.

Experienced, single setting
75th
$78,680
Experienced, high-cost market or hard-to-staff setting
90th
$89,510
Senior, specialized, or travel and per diem
Budget past the wage: payroll taxes, benefits, professional liability coverage, continuing education, and licensure renewal all sit on top. The occupation held about 111,500 jobs in 2024, and employment of physical therapist assistants and aides is projected to grow sixteen percent from 2024 to 2034, well above the average for all occupations, with roughly 19,800 openings a year. In a market that tight, a slow decision loses the candidate.
Fair, Legal, and Structured Interviewing
A fair interview, a legal one, and an accurate one are the same interview. Asking every candidate the same job-related questions keeps you compliant, reduces bias, and produces the better hire at the same time. For a PTA role the specific hazard is the physical side of the work.
Ask about the job, not the person
Federal anti-discrimination law, enforced by the EEOC, prohibits basing hiring decisions on protected characteristics, and questions that probe them create risk even when they are asked as small talk. Keep away from age, race, religion, national origin, sex, pregnancy or family plans, disability, and genetic information. In a PTA interview the specific trap is the physical side of the job: because the work involves transfers, guarding, and long days standing, it feels natural to ask whether a candidate has ever hurt their back or how much they can lift. Ask instead whether they can perform the essential functions of the job, with or without a reasonable accommodation, and put those functions in the posting first. This is general information, not legal advice.
Ask every candidate the same core set
A structured interview, where each candidate answers the same questions scored against the same rubric, predicts on-the-job performance better than a free-flowing conversation, and it makes a hiring decision far easier to stand behind. For a small clinic this is the highest-leverage habit available: write the questions in advance, ask them in the same order, and score them the same way. The scope and supervision set is the one to keep constant no matter how the conversation goes, because it is the set that protects the practice. The downloadable question sets and the scorecard here are built to make that routine rather than an effort.
Score independently, then discuss
When the owner and a lead therapist both interview, each should fill in the scorecard alone before the two of you talk. This keeps the more senior or the more talkative voice from anchoring the other, which is a common way a weak candidate gets talked into a job and a quiet strong one gets talked out of it. Compare the written evidence first and the impressions second. A 1-to-5 rubric per area, completed independently, turns a subjective debate into a decision you can explain, and it gives you something to look at again if the hire does not work out.
Weight the questions to your setting
A PTA in a busy outpatient orthopedic clinic and a PTA covering a home health route are doing different jobs with the same credential, so weight the sets to your reality. Outpatient practices should lean on the core treatment set and the overlap questions in the outpatient block. Skilled nursing should lean on the productivity and documentation-honesty questions. Home health should lean on safety, autonomy, and how the candidate reaches the supervising PT from the field. Every setting keeps the scope and supervision set intact, because that one is not optional anywhere.
Because the job involves transfers, guarding, and long days standing, it feels natural to ask whether a candidate has back problems or how much they can lift. Under the ADA you generally may not ask disability-related questions or require a medical examination before a conditional offer. Write the essential functions into the posting, then ask whether the candidate can perform them with or without a reasonable accommodation.
Same Questions, Same Rubric, Better Hires
A structured interview, where every candidate answers the same questions scored against a consistent rubric, predicts on-the-job performance more reliably than an unstructured conversation, and asking the same job-related questions of everyone also keeps you inside the EEOC rules against basing decisions on protected characteristics. Structure is the fairer approach and the more accurate one at once.
Score each candidate on the same rubric right after the interview while it is fresh, anchoring every score to something they actually said. That habit is the core of a structured interview, and it gives you something to look at again later.
Interviewing a PTA Without an HR Department
A hospital system runs a PTA candidate through a recruiter, a rehab manager, and a panel. A small practice runs the whole thing through the owner, usually between patients, and often without any training in how to interview at all. Here is how to close that gap at your size.
You are the owner, the clinical lead, and the only interviewer
At a hospital system a PTA candidate meets a recruiter, a rehab manager, and a panel, and someone else keeps the scorecards. At a two-clinician practice the owner runs the whole interview between patients, and often has never been taught how. The sets here are built for that: pick the blocks that match your setting, ask the same core questions of every candidate, and write the answers down as you go. The point is to make one owner’s interview as rigorous as a full hiring team’s, without the overhead of one.
The scope question is the one you cannot skip when you are busy
When a schedule is full and a candidate is warm and available, the easiest thing to skip is the least comfortable set. That is exactly backwards. A PTA who believes they may evaluate a patient, alter a plan of care, or discharge on their own is a clinical and a regulatory exposure for the practice that employs them, and the interview is the cheapest place to find out. Ask the scope and supervision questions of every candidate, in the same words, and write down what they answered. Two minutes of discomfort in the interview is worth a great deal later.
The interview is step one; the license check and the first week are where it gets real
Once you choose a PTA, the work shifts from evaluating to hiring well: verify the license on the state board site and save the dated result, confirm the accredited program, send a clear offer, and run the new hire paperwork and a structured first week so the person is safe and useful quickly. FirstHR fits that people side for a small practice: send the offer for e-signature, run the onboarding workflow and policy sign-offs, and keep the signed documents, the license verification, and the interview scorecards on the employee profile. FirstHR is an onboarding and HR platform, not an electronic medical record, a billing system, or a scheduling tool, so pair it with those. Applicant tracking is coming soon to FirstHR.
Stage
What to do
1. Post
Write the essential functions, the setting, and the supervision arrangement into the posting
2. Screen
Short call: license status, setting experience, schedule, pay range
3. Interview
Core and scope sets for everyone, plus safety and your setting block
4. Score
1 to 5 on the rubric with evidence, independently if two people interview
Move fast once the scorecards are in; strong candidates have options
If you are running more than two candidates at once, keep the scorecard totals and the verification status in one list rather than in your inbox, so nobody goes cold while you are on the schedule. Applicant tracking is coming soon to FirstHR, and until then a single shared sheet with a row per candidate does the job for a practice this size.
From Interview to First Week
The interview is step one. Once you choose someone, the job shifts to hiring well: verify the credential, send a clear offer that names the setting, the schedule, the supervising therapist, and the pay, then run the new hire paperwork so nothing is chased down in week two.
Verify and record the credential
License lookup on the state board site, accredited program confirmed, exclusion list searched, each with the date and result saved to the file.
Send the offer
Confirm the setting, the schedule, the supervising therapist, and the pay in writing, with e-signature so the record is clean.
Run the paperwork
New hire forms, policy and safety acknowledgments, and any required health documentation collected and stored in one place.
Structure the first week
Shadowing, the supervision arrangement in writing, documentation standards, and a check-in at the end of week one.
Put the supervision arrangement in writing on day one, alongside the standard I-9 and W-4 and an onboarding plan for the first week. A PTA who knows exactly who supervises them, how to reach that person, and what triggers a same-day call is safer in week one than one who is left to work it out.
FirstHR connects the offer, the e-signature, the new hire paperwork, the policy acknowledgments, and the onboarding workflow in one place, and keeps the signed documents, the license verification, and the interview scorecards on the employee profile, so a small practice can run hiring through to onboarding from a single system. FirstHR is an onboarding and HR platform, not an electronic medical record, a billing system, or a scheduling tool, so connect those separately. Applicant tracking is coming soon to FirstHR.
Key Takeaways
Assess a PTA on treatment delivery inside a plan of care, scope and supervision, escalation, patient handling, setting fit, and behavioral evidence.
Ask what stays with the physical therapist first; a candidate who describes evaluating or discharging alone is a regulatory exposure.
Ask what would make them stop a session and call the supervising PT the same day, and expect concrete triggers.
Ask about the essential functions of the job, never about back problems, injuries, or medical history.
Verify the license on the state board site yourself and save the dated result, along with the accredited program and an exclusion list search.
Use BLS data as the anchor: a median of $68,380 a year, about $32.88 an hour, in the May 2025 survey.
Score every candidate on the same 1-to-5 rubric with written evidence, independently if two people interview.
Frequently Asked Questions
What questions should I ask a physical therapist assistant candidate?
Ask across six areas: core treatment delivery, scope and supervision, patient handling and safety, your specific practice setting, behavioral evidence, and the reasons behind each answer. The strongest single question is what a PTA may do and what stays with the physical therapist, because a candidate who is fuzzy there is a compliance exposure as well as a clinical one. Follow it with what would make them stop a session and call the supervising PT the same day, how they progress an exercise inside a plan of care, and a transfer walkthrough with weight-bearing restrictions. Then ask for real examples: a patient who was not progressing, a disagreement with a supervising therapist, a time they were asked to do something outside their comfort. Ask the same core set of every candidate and score it on a rubric rather than deciding on rapport.
What is the difference between a physical therapist and a physical therapist assistant?
The physical therapist evaluates the patient, writes the plan of care, performs re-evaluations, and makes the discharge decision. The physical therapist assistant delivers the interventions inside that plan, collects objective data, teaches home programs, and reports back to the PT. A PTA works under the direction and supervision of a physical therapist and may not evaluate a patient, write or alter the plan of care, or discharge independently. The education differs as well: a PT holds a doctoral degree, while a PTA completes an accredited associate degree program and a licensing examination. The exact supervision requirement, including whether the PT must be on the premises or only reachable, is set by each state practice act and by the payer, so it changes when a clinician moves states. A physical therapy aide is different again: unlicensed support staff who may not deliver skilled treatment.
What should I ask about scope and supervision in a PTA interview?
Ask four things directly. First, what can a PTA do and what stays with the physical therapist; you want the evaluation, the plan of care, re-evaluation, and discharge named as the PT's without hedging. Second, what supervision the candidate has worked under and whether they know it is set by the state and the payer rather than by the clinic. Third, what would make them stop a session and call the supervising PT the same day, which tests escalation judgment. Fourth, how they handle disagreeing with a plan of care, where the answer you want is that they raise it with the PT and do not change it alone. Also ask what goes in their note versus the PT note. A candidate who describes writing plans or discharging patients on their own is telling you how they will practice in your clinic.
Can I ask a PTA candidate about lifting, back problems, or physical ability?
You can ask about the job, not about the person's health. Under the Americans with Disabilities Act you generally may not ask disability-related questions or require a medical examination before a conditional offer, which rules out asking about back problems, past injuries, workers compensation claims, or medical history. What you may do is write the essential functions into the job posting, including patient transfers, supporting adult body weight, standing for most of a shift, and helping a patient to the floor and back, and then ask every candidate whether they can perform those functions with or without a reasonable accommodation. Ask it in the same words each time. If a candidate raises an accommodation, discuss it rather than screening them out. This is general information, not legal advice.
How do I verify a physical therapist assistant license?
Look the candidate up yourself on your state licensing board website rather than accepting a copy of a license card or a screenshot. Record the date you searched, the license number, the status, and any disciplinary history, and keep that record in the employee file, because the question a year from now is whether you checked and a memory of checking is not an answer. Confirm graduation from an accredited PTA program as well, since that education requirement sits behind the credential. If your practice bills any federal health program, also search the federal exclusion list before hire and save the dated result, because employing an excluded individual carries its own penalty. Repeat the license check at each renewal cycle. Reference checks should include at least one physical therapist who actually supervised the candidate.
How much does a physical therapist assistant earn?
According to the Bureau of Labor Statistics Occupational Employment and Wage Statistics survey (May 2025), physical therapist assistants had a median annual wage of $68,380, about $32.88 an hour. The lowest ten percent earned under $47,750 and the highest ten percent above $89,510, with the twenty-fifth percentile at $59,820 and the seventy-fifth at $78,680. Physical therapy aides, an unlicensed role, sat far lower at a median of $35,240. Budget past the wage itself: payroll taxes, benefits, professional liability coverage, continuing education, and licensure renewal all sit on top of it. Employment of physical therapist assistants and aides is projected to grow sixteen percent from 2024 to 2034 according to the Occupational Outlook Handbook, well above the average for all occupations, so a slow hiring process loses candidates to faster employers.
Does hiring a PTA instead of a PT change what I get paid?
For Medicare Part B outpatient therapy, yes. Under the Centers for Medicare and Medicaid Services rules, outpatient therapy services furnished in whole or in part by a physical therapist assistant are billed with the CQ modifier and paid at 85 percent of the otherwise applicable Part B amount, effective January 1, 2022. The modifier applies when the PTA furnishes more than 10 percent of the minutes of a service, the standard usually called the de minimis threshold. That does not make hiring a PTA a bad decision, since the wage difference between a PTA and a physical therapist is far larger than the payment adjustment, but it does mean your staffing model has a billing consequence you should model before you hire. Commercial payer rules vary. This is general information, not billing or legal advice.
How long should a PTA interview be, and how many rounds?
Plan 45 to 60 minutes for a single focused interview, which is enough to cover the core treatment set, the whole scope and supervision set, the safety questions, and the block for your setting, with follow-ups. Depth beats breadth: the probe after a good question tells you more than ten extra questions do. Most small practices run two touchpoints, a short phone screen for licensure, setting experience, schedule, and pay range, then the full interview in the clinic. A working interview or a shadowing hour is common in this field and is genuinely informative, but treat compensation and licensure requirements for any hands-on time carefully and check your state rules first. Score immediately afterward while the answers are fresh, and if a second person interviews, have each score independently before you discuss.
