Arizona, West Virginia, South Carolina, North Dakota, Alaska, Michigan, Nebraska and Illinois test your home scope or certifications before endorsing you. If yours is narrower, the options are CELMO where accepted (Arizona, Connecticut, Iowa, Wyoming), the regular application on recent NBEO scores, or earning the missing certification first.
Optometric scope is set state by state, and the gap between the broadest and narrowest practice acts is wide. That gap shows up in licensing. A number of boards will license an optometrist from another state only if the scope that optometrist practices at home is at least as broad as the board's own, or only if the optometrist already holds certain certifications. An optometrist from a narrower-scope state can be fully qualified on paper, with every NBEO part passed, and still not fit the endorsement route.
The fix is usually available, but it changes which route you use, which documents you gather and sometimes how long the move takes.
Which boards compare your home scope to theirs?
- Arizona. Endorsement requires four of the last five years of practice in one jurisdiction whose scope is equal to or higher than Arizona's, and current practice at that level (A.R.S. § 32-1723). An optometrist from a narrower-scope state may use a CELMO certificate instead, or apply as a regular applicant with NBEO scores from the last 10 years. Every applicant passes Arizona's jurisprudence exam through NBEO's online system.
- West Virginia. Reciprocity needs five of the last seven years of practice and, since July 2025, oral, injection and laser certification before you apply. Every West Virginia license now carries all three. The ISE or a board-approved injection course and the LSPE or a board-approved laser course are the usual evidence. See West Virginia licensing.
- South Carolina. Endorsement is for optometrists currently practicing at the therapeutic level and authorized to treat glaucoma, with therapeutic practice in the preceding 12 months or 24 of the last 36 (S.C. Code 40-37-245; Reg. 95-5).
- North Dakota. Endorsement applicants apply at North Dakota's highest therapeutic level, are current on CE, pass the state law exam and sit an oral interview unless the board waives it (N.D.C.C. 43-13-18).
- Alaska. License by credentials requires practice at the highest therapeutic level authorized in your jurisdiction, 3,120 practice hours in the last 36 months and a board-approved nontopical injection course of at least seven hours (12 AAC 48.020).
- Michigan. Endorsement applicants show therapeutic certification at the highest level authorized where they currently practice.
- Nebraska. Reciprocity applicants need a credential at a level at least as stringent as the Nebraska credential they seek, plus two of the last three years of practice (Neb. Rev. Stat. 38-2609).
- Illinois. Every applicant must qualify for diagnostic, topical therapeutic and oral therapeutic authority.
- Delaware. Delaware issues only therapeutic licenses and compares both the basic and therapeutic standards of your home jurisdiction. Applicants send copies of the optometry law and rules of each jurisdiction where they practiced.
- Idaho. The board must approve the education, training and exams behind the diagnostic and therapeutic privileges you hold elsewhere (IDAPA 24.10.01.100.04).
Other boards set a floor for every applicant rather than comparing states: Missouri requires every applicant to qualify for TPA certification, Ohio's endorsement rule requires three years of practice that includes therapeutics, and New Mexico folds TPA into every license, so its expedited route is open only to optometrists who hold TPA certification.
Is there a way around a narrower home scope?
Use CELMO where the state accepts it
ARBO's CELMO certificate exists for this problem. Arizona names it as the alternative for applicants from narrower-scope states. Connecticut's statute allows a license for a holder of a CELMO certificate on payment of the fee. Iowa accepts it as one of five proofs of current competence. Wyoming has a separate Optometrist by CELMO Endorsement application ($800, with the jurisprudence exam and fingerprints). CELMO does not license you anywhere by itself, and ARBO says there is no guarantee a board will grant a license. Details in CELMO certificates: what they do and where they count.
Minnesota is a reminder that CELMO is not the only kind of national evidence. Its endorsement statute accepts documentation from a board-approved national certification program, without naming CELMO, so ask the board what it will take before you buy anything.
Apply as a new applicant instead of by endorsement
Endorsement tests your practice; the regular application tests your exams. Arizona lets an optometrist outside its endorsement criteria apply as a regular applicant if NBEO scores fall within the last 10 years. Recent graduates often find the regular route simpler for that reason.
Earn the missing certification first
When a board requires a certification you do not hold, the order matters. West Virginia will not take the application until the oral, injection and laser certifications are in place. Illinois's oral therapeutic requirement may mean documenting school coursework or a course. Hawaii's TPA certification includes a 100-hour preceptorship under an ophthalmologist, and Arkansas's optometric physician certification a 100-hour internship. Our guide to TPA, orals and legend drug certificates lists the variations.
Use universal recognition where it fits
Arizona also has universal recognition under A.R.S. § 32-4302 for new residents holding an Arizona driver license and at least one year of licensure elsewhere. West Virginia's universal licensing law (W. Va. Code 30-1-27) is tied to new residency or a military spouse's posting, and Ohio's statute points out-of-state optometrists to Chapter 4796. These routes have their own conditions; read them before assuming they bypass a scope test.
What if the new state allows less than you do now?
This direction surprises more people. Your license in the new state carries that state's scope, not yours. If you perform SLT or YAG capsulotomy at home and move to a state whose act excludes lasers, such as Connecticut, Maine, Nevada, Oregon or Wisconsin, you cannot perform them there. Massachusetts limits optometrists to Schedule VI prescription drugs, excluding controlled substances, most injections and invasive surgery. South Carolina limits oral agents to listed categories. Montana names specific analgesics. Practice to the new act from day one, and update protocols, prescription pads and EHR order sets.
For practices hiring across state lines, that means the same optometrist may have different privileges at two of your locations. See licensing optometrists for multi-state practices.
How do you prove your scope on paper?
- NBEO score reports, sent directly by NBEO, showing TMOD and, where relevant, the ISE and LSPE.
- Your school transcript, showing pharmacology and clinical hours. Several boards split requirements by graduation year.
- License verifications from every state you have held, showing the certification level, not only good standing.
- Practice verification that shows the level you practice at, which South Carolina and Arizona both test. An employer letter that says "optometrist" without describing therapeutic practice may not be enough.
- Certificates and logs for injection, laser or glaucoma training, including proctor or preceptor logs.
- A copy of your home state's practice act, which Delaware asks for outright and other boards may request.
Gather these before you apply, not after a deficiency letter. A board that has to ask for proof of therapeutic practice or a missing course certificate usually holds the whole file until it arrives, and boards that interview applicants at scheduled meetings, such as Arkansas and West Virginia, can push the interview to the next meeting date.
Does a Kentucky waiver problem count as a scope mismatch?
No, but they can look alike to a board. A Kentucky licensee who received a waiver of an NBEO part may have broad scope at home and still lack the exam record another board requires. That is an exam gap, not a scope gap, and it is covered in Kentucky's waived licenses and moving.
Where do we come in?
The Optometry Licensing Readiness Review ($149, credited in full toward a first application) compares your current tier, NBEO record, graduation year and practice history with the target state's tests and tells you which route fits: endorsement, the regular application, CELMO or a certification first. The license itself is $699 per state, certifications are $249 each, and laser or advanced procedure credentials are $399 per state. CELMO Certificate Help is $299 plus ARBO's fee. You sign every application and attestation. See pricing and the Arizona and South Carolina state pages.
Common questions
- Can I use CELMO if my home state has a narrower scope than Arizona?
- Yes. Arizona accepts a CELMO certificate to meet endorsement requirements for applicants whose home state's scope is narrower than Arizona's. You still pass Arizona's jurisprudence exam.
- Do I need laser certification before applying in West Virginia?
- Yes. Since July 2025, West Virginia requires oral, injection and laser certification before you apply by reciprocity, usually shown with the ISE and LSPE or board-approved courses.
- If I move to a state with narrower scope, can I keep doing what I did at home?
- No. Your license in the new state carries that state's scope. If its practice act excludes lasers or certain drugs, you cannot perform or prescribe them there, whatever your home license allows.
- Does South Carolina accept optometrists who do not treat glaucoma?
- Not by endorsement. South Carolina requires current therapeutic practice and authority to treat glaucoma in your home state.
