Can I work as an OT once I pass the NBCOT exam?

Not on the exam alone. You need a state license, or a limited permit or temporary license where the state offers one. NBCOT itself says certification is not the same as licensure.

Do I have to keep NBCOT certification to keep my state license?

It depends on the state. South Carolina requires current, good-standing NBCOT certification to maintain and renew a license. Many states do not, though some, like Maryland and Oregon, let it stand in for continuing education.

Does renewing NBCOT renew my state license?

No. They are separate renewals with separate fees and calendars. NBCOT renews every three years between January and March; each state sets its own cycle.

What does it cost to reinstate lapsed NBCOT certification?

NBCOT's fee schedule lists $125 within three years of expiration and $175 after that.

NBCOT Certification and Your State License Are Two Different Things

NBCOT certification is a national professional credential; a state license is the legal permission to practice. You need the license (or an OT Compact privilege) to work as an occupational therapist or OTA in any state. NBCOT says so directly on its own site: "Certification is not the same as licensure. Follow these additional steps to obtain a license."

The confusion is understandable. You study for one exam, pass it, and suddenly have letters after your name. But the letters come from a private certifying body, and the authority to treat patients comes from a government board in each state where you work.

Who issues each credential?

The National Board for Certification in Occupational Therapy grants two credentials: OTR (Occupational Therapist Registered) to graduates of ACOTE-accredited OT programs who pass its exam, and COTA (Certified Occupational Therapy Assistant) to graduates of ACOTE-accredited OTA programs, according to NBCOT's eligibility page. Certification lasts three years and renews through NBCOT.

State licenses come from state boards created by each state's practice act. The US Bureau of Labor Statistics says in its Occupational Outlook Handbook that all states require occupational therapists to be licensed. The board name and structure vary: Virginia licenses OTs through its Board of Medicine (18VAC85-80), Ohio through a combined occupational therapy, physical therapy and athletic trainers board, and New York through the State Education Department's Office of the Professions.

How do the two connect?

The NBCOT exam is the gate. Nearly every state board names it as the licensing exam. Washington's rule is typical: the board "recognizes the examination administered by the National Board for Certification in Occupational Therapy" as the official exam for licensure (WAC 246-847-080). Georgia's rule says all applicants must pass the exam administered by NBCOT, and that NBCOT sets the passing score (Ga. Comp. R. & Regs. 671-3-.03, .04).

So the relationship runs one way. Passing NBCOT's exam is a requirement for the license. Holding the license does not depend, in most of the states we have checked, on keeping NBCOT certification current afterward.

Where does the line blur?

A few states tie the license to current certification

South Carolina is the clearest example. Its Board of Occupational Therapy states that it "requires initial and ongoing certification" with NBCOT, and that licensees "must be certified and in good standing with NBCOT in order to maintain and renew their SC license." An OT who lets NBCOT certification lapse in South Carolina has a licensing problem, not just a credential problem.

Some states let certification count toward continuing education

Maryland's 2026 application form says that if you do not maintain current, active NBCOT certification, you must document 24 contact hours completed in the preceding 24 months. Oregon says maintaining current NBCOT certification "may be used to satisfy the requirements for CE," though not its cultural competency hour or pain management module. Ohio will accept current NBCOT certification in place of another state license for an endorsement applicant (Ohio Admin. Code 4755:1-1-01(F)).

Title protection follows the license

Using "occupational therapist" or "occupational therapy assistant" in a state is governed by that state's law. New York's license requirements page says any use of those titles in the state requires a New York license. Your OTR or COTA initials describe your certification; they do not license you to practice in New York.

Which mistakes come from mixing them up?

Starting work after passing the exam, before the license issues. Unless the state has a limited permit or temporary license you actually hold, passing the exam alone does not authorize practice. New York warns that both the employer and the employee may be prosecuted if an OT is employed without a license or limited permit. See temporary and limited OT licenses.
Assuming NBCOT renewal took care of the state. They run on different calendars and require separate applications. NBCOT renews every three years, between January and March; Texas renews every two years by the end of your birth month (40 Tex. Admin. Code § 370.1). See NBCOT renewal and state license renewal.
Sending a certification verification when the board wants a score. Texas requires the score report sent directly from NBCOT and treats a verification as a different document. Details in sending your NBCOT score to a new board.
Thinking one credential covers every state. National certification travels with you; a license does not. Practicing in a second state takes a second license or, where both states issue them, an OT Compact privilege. As of October 2026, ten states issue privileges, according to otcompact.gov.

Does a lapsed NBCOT certification affect a license application?

It can. Maryland's form asks for your current NBCOT status (active, inactive, retired, or pending results) and adds the 24-hour documentation requirement if you are not current. And NBCOT itself says that if you did not renew within your renewal year, you must apply for reinstatement and be approved "before using your OTR or COTA credential." Reinstatement costs $125 within three years of expiration or $175 after, per NBCOT's fees page.

A separate NBCOT process, state reactivation, exists for people whose state requires them to retake the exam after time away from practice. NBCOT says the state board must approve your eligibility first, and that retaking the exam for state reactivation "does not affect your current NBCOT certification." Our post on reinstating a lapsed OT license covers the state side.

Which one should you keep current?

Every state license where you practice, always. NBCOT certification is a judgment call in most states, but it is mandatory in South Carolina, it can simplify continuing education in Maryland and Oregon, many employers ask for it, and letting it lapse means a reinstatement application before you can use the initials again. Most OTs we work with keep both.

How do we help?

We handle the state side: license applications, renewals and continuing education tracking across every state where you hold a license. Our Annual Renewal and CE Compliance service is $299 per license, per year and tracks state deadlines alongside your NBCOT cycle so the two never get confused. We do not renew NBCOT certification for you or complete CE on your behalf; we make sure you know what each body needs and when. Browse state requirements in the state license index.
