ABO certification is a national credential from ABO-NCLE, a private certifying board; an optician license is permission to practice granted by a state. Many licensing states use the ABO and NCLE exams as part of licensure. Others add their own practical or law exam. BLS notes some states require state-specific examinations.

How licensing states use national exams
From the official boards we verified (each linked; checked Oct 8–9, 2026):
States that use the ABO/NCLE exams
- California optician license: the board requires SLD and CLD applicants to “pass the related ABO–NCLE Exams.”
- Hawaii optician license: NOCE and CLRE for all methods of licensure.
- Florida optician license: NOCE and CLRE, with the national ABO and NCLE practicals as Part 3.
- New York optician license: NOCE (or a comparable exam) and the ABO Practical (ABOP).
- Washington optician license: ABO/NCLE exams and practicals; no state-administered exam since March 15, 2018.
- Nevada optician license: ABO and NCLE Basic, Advanced and Practical for the full license.
States that add their own exam
- Connecticut optician license: a DPH-administered practical with Eyewear and Contact Lens components, plus NOCE and NCLE.
- Nevada: the Nevada Laws and Ethics Exam (open-book), after the certifying exams.
- Virginia optician license: written and practical exams applied for through the Board, which lists ABO/NCLE as the exam administrator.
- Tennessee: its rule names a Tennessee Dispensing Optician Examination and a Tennessee Jurisprudence Examination (Tenn. Comp. R. & Regs. 0480-01-.08).
Arizona’s board says it “no longer Administers the practical examination,” which is “now administered by nationally recognized bodies” (Arizona board).

Moving to another state
Licenses are state-issued; ABO certification is national. Check the new state’s board for an endorsement route. Florida lists “licensure by endorsement”; Hawaii says it “does NOT reciprocate.” We haven’t verified other states’ endorsement rules.
If your state doesn’t license opticians
ABO certification is voluntary there. BLS notes employers “may require or prefer” certification (BLS).

Frequently asked questions
What’s the difference between ABO certification and a state license?
ABO certification is a national, voluntary credential from ABO-NCLE, a private board. A license is a state’s permission to practice. A state can require the ABO exam for its license, but passing it doesn’t make you licensed.

Do states have their own optician exams?
Some do. Among states we verified, Connecticut runs a DPH practical exam, Nevada requires its Laws and Ethics exam, and Tennessee’s rule names a Tennessee Dispensing Optician Examination and a Tennessee Jurisprudence Examination. BLS notes some states “require opticians to pass state-specific examinations.”

If I move, does my optician license or ABO certification move with me?
ABO certification is national, so it stays with you. A license is issued by one state, so you apply in the new state. Florida, for example, lists “licensure by endorsement”; Hawaii says it does not reciprocate. Check the new state’s board.

Do I need ABO certification if my state licenses opticians?
Often you need the ABO exam, not necessarily ongoing certification. Several verified states name ABO-NCLE exams in their licensing rules. Check your board for its exact wording.

Is the state practical exam the same as the ABO practical?
Not always. Florida, New York and Washington use the national ABO (and NCLE) practicals. Connecticut runs its own DPH practical with Eyewear and Contact Lens components.
