## What is COTA certification?

COTA certification is the national credential for occupational therapy assistants in the United States, issued by the National Board for Certification in Occupational Therapy (NBCOT). It confirms that you graduated from an accredited occupational therapy assistant program and passed the national exam, and it gives you the right to use the COTA mark after your name. You earn it once and keep it active by renewing every 3 years. Every state then requires a separate license before you can treat patients, and most employers ask for the certification on the job posting. Many assistants write their credential as COTA/L, where the "/L" shows the state license you hold in addition to the NBCOT certification.

## COTA vs OTR

A COTA delivers therapy under supervision, and an OTR runs the evaluation and the plan. Both are NBCOT credentials earned by exam, but they sit at different levels of training and responsibility. NBCOT describes the split directly: the OTR evaluates the client and plans the interventions, while the COTA carries out and documents those interventions and reports the client's progress back to the OTR.

| Field | Value |
| --- | --- |
| COTA | Certified Occupational Therapy Assistant. Trained at the associate-degree level in an ACOTE-accredited OTA program. Delivers treatment, documents it, and works under an OTR's clinical supervision. Passes a 190-item NBCOT exam. |
| OTR | Occupational Therapist Registered. Trained at the master's or doctoral level. Evaluates the client, builds the treatment plan, and holds overall clinical responsibility for care. Passes a separate 180-item NBCOT exam. |

If you already hold the COTA and later finish an occupational therapist degree, you apply to NBCOT again and sit the OTR exam. The assistant credential doesn't convert on its own.

## Who requires COTA

Employers ask for COTA on occupational therapy assistant postings, because the credential is what makes you licensable in almost every state. In our US listings that means occupational therapy assistant roles across skilled nursing facilities, hospitals, outpatient rehab clinics, school districts, home health agencies, and pediatric or early-intervention programs. The [occupational therapist](/guides/occupational-therapist-license) and occupational therapy aide roles nearby are different jobs: the therapist runs evaluations and the aide supports the department without a treating credential. COTA is what lets the assistant bill therapy, which the aide can't do.

## Requirements and eligibility

NBCOT sets a short list of requirements to sit for the COTA exam.

- **Education.** You must graduate with an entry-level occupational therapy degree from an OTA program accredited by the Accreditation Council for Occupational Therapy Education (ACOTE). That is an associate-level program at most schools.
- **Fieldwork.** You must finish the supervised fieldwork built into your program before you submit your application. The clinical hours happen inside the program, so you don't need separate paid work experience to test.
- **Transcript.** NBCOT requires your school to send an official final transcript before it grants certification. Your degree has to be awarded, or its conferral certain, when you apply.
- **Character review.** You answer conduct questions on the application and disclose any criminal charges or professional discipline. If a past issue concerns you, NBCOT offers an Early Determination Review you can file before you apply.

You don't need a state license to sit the exam. Licensure comes after you pass, and it's a separate application to your state board.

## COTA certification and your state license

Passing the NBCOT exam is not the same as holding a license, and you need both to work. Every state plus the District of Columbia licenses occupational therapy assistants, and most of them accept the NBCOT exam as the qualifying standard, so you apply to NBCOT and to your state board on your own. NBCOT can send a Score Transfer or an Eligibility Confirmation Notice straight to a state board when you ask for it at application. Rules vary: a few states run extra requirements such as a jurisprudence exam, and Hawaii doesn't take an NBCOT Score Transfer at all. Check your board before your first job, because where the state requires a license, the employer needs to see it.

## How to get certified

1. Enroll in and graduate from an ACOTE-accredited occupational therapy assistant program, and complete its supervised fieldwork.
2. Read the NBCOT Certification Exam Handbook, and answer the character-review questions honestly. File an Early Determination Review early if a past charge concerns you.
3. Create a MyNBCOT account, submit the COTA exam application, and pay the $540 online fee. Have your school send your official final transcript. The [NBCOT website](https://www.nbcot.org/) holds the current handbook and fee schedule.
4. Schedule your exam at a Pearson VUE center once you receive your Authorization to Test letter, and pass the 190-item exam within your 90-day window.
5. Apply to your state board for a license, using a Score Transfer or Eligibility Confirmation Notice from NBCOT.
6. Renew your NBCOT certification every 3 years with 36 units, and renew your state license on its own schedule.

## Demand for COTA on MedJobList

COTA is named in 79 of the active US openings we track right now. Those are occupational therapy assistant roles, mostly in skilled nursing and outpatient rehab settings where employers list the credential as required. You can browse them in the section below, or filter the full job list by COTA yourself.

## On the job

Keep both your certification and your state license current, because a lapse in either one can pull you off the treatment schedule. Employers and boards verify NBCOT status directly, so an expired certification shows up fast. Ask at onboarding who covers your continuing education: many rehab employers pay for the courses that earn your 36 units, and some reimburse the renewal fee, so raise it in the interview before you pay out of pocket.
