An entry-level OTD trains you to become an occupational therapist. A PhD in occupational therapy trains occupational therapists to do research. Only the OTD (or an OT master’s) qualifies you for the NBCOT exam and a state license. PhD programs generally admit people who already have an OT degree, and they lead to research and university faculty careers.
The three OT doctorates
| Compared | Entry-level OTD | Post-professional OTD | PhD in OT |
|---|---|---|---|
| Who it’s for | Bachelor’s graduates who want to become OTs | Practicing OTs | OTs who want a research career |
| Leads to an OT license | Yes (NBCOT exam, then state license) | No (you’re already licensed) | No |
| Accredited by ACOTE | Yes, 231 programs in the ACOTE directory | No | No |
| Focus | Clinical practice, fieldwork and a doctoral capstone | Leadership, advanced practice and teaching | Original research and a dissertation |
| Typical format | Full-time, on campus or hybrid | Often online, while working | Full- or part-time; varies by school |

Entry-level OTD: the clinical doctorate
The entry-level OTD is one of two ways to become an occupational therapist; the other is an entry-level master’s. Both are accredited by ACOTE and lead to the same NBCOT exam and state license. ACOTE says there is no mandate to move OT education to the doctoral level, so master’s programs remain a full route into the profession.
Compared with a master’s, the OTD adds a doctoral capstone, usually takes longer and costs more. The median published OTD tuition is $106,696. The University of Kansas, for example, describes its entry-level OTD as a three-year, full-time degree for students with a bachelor’s degree.

Post-professional OTD: a doctorate for working OTs
A post-professional OTD is for therapists who already hold a license. Salus University notes that its post-professional OTD is completed online while students work full-time as OTR/Ls. These programs are not ACOTE-accredited and don’t lead to licensure; they build skills in leadership, education and advanced practice.
PhD in occupational therapy: the research doctorate
A PhD prepares you to run research studies and teach at universities. Admission generally requires an OT degree:
- Nova Southeastern University requires a bachelor’s or master’s degree in occupational therapy and eligibility to practice within one year of starting (program page).
- New York University requires graduation from an approved professional OT program and NBCOT certification or eligibility, plus a master’s, entry-level OTD or equivalent (admissions page).
- Texas Woman’s University describes its PhD as preparing occupational therapists for scholarly careers in academia and practice, with at least 90 graduate credit hours beyond the bachelor’s, including at least 45 in the doctoral program (program page).
Which should you choose?
- You want to work as an OT: choose an ACOTE-accredited master’s or entry-level OTD. Use the Program Finder to compare them.
- You’re an OT who wants to lead or teach clinically: a post-professional OTD fits around a full-time job.
- You’re an OT who wants a research career: a PhD is the research degree; ask each program about funding and faculty mentors.
