ABO-NCLE describes its basic exams as being for opticians and contact lens technicians working in any type of practice in the U.S. The ABO Basic exam focuses on spectacle dispensing: optics, frames and lenses, measurements, and standards.

No. ABO certification is a national certification from ABO-NCLE, while a license is issued by a state, and only some states license opticians. Licensing states may use ABO-NCLE exams in their process, and ABO-NCLE tells candidates to confirm their state’s requirements before registering.

The ABO Basic exam (NOCE) tests eyeglass dispensing knowledge, while the NCLE Basic exam (CLRE) tests contact lens fitting and dispensing. Both come from ABO-NCLE with the same 125-question, 2-hour format and the same fee, and you can hold both certifications.

No. ABO-NCLE requires only a high school diploma, GED, or equivalent for the NOCE, with exceptions for high school students in dual-enrollment programs. It notes that candidates with two to three years of hands-on experience or an optical school program tend to pass at higher rates, and state licensing rules apply on top of ABO-NCLE’s if they differ.

You can register again after waiting 14 days from your test date, and you pay the full fee for each new attempt.

ABO certification is not tied to a state, but a state license is a separate credential and does not automatically transfer. ABO-NCLE sends licensing boards rosters of candidates from their state and will send your results to another state’s board on request.
