IJCAHPO — the International Joint Commission on Allied Health Personnel in Ophthalmology, formerly JCAHPO — certifies allied ophthalmic personnel on a three-level ladder.
The core levels are COA (Certified Ophthalmic Assistant), COT (Certified Ophthalmic Technician) and COMT (Certified Ophthalmic Medical Technologist), with specialty credentials such as the OSC and OSA offered alongside them.
This page explains what each level requires, what the exams and fees cost, and how recertification works.
What is IJCAHPO?
IJCAHPO — the International Joint Commission on Allied Health Personnel in Ophthalmology, formerly JCAHPO — is the certifying body behind the COA, COT and COMT credentials for allied ophthalmic personnel.
Its site still answers at jcahpo.org, and some of its own documents still carry the shorter JCAHPO name.
Three core levels make up the ladder: Certified Ophthalmic Assistant (COA), Certified Ophthalmic Technician (COT) and Certified Ophthalmic Medical Technologist (COMT).
IJCAHPO describes the three levels as a solid ladder for progressive career development — assistant first, then technician, then technologist.
Beyond the core, IJCAHPO runs specialty certifications and certificates of completion, which this page covers in its own section.
The credentials this page covers under the heading of ophthalmic technician certification are those core levels plus the specialty credentials IJCAHPO offers alongside them.
IJCAHPO is a separate system from the American Optometric Association's paraoptometric credentials — the CPO, CPOA, CPOT and CPOC, developed and administered by the AOA's Commission on Paraoptometric Certification.
The two systems are separate: each body sets its own eligibility, exam and renewal rules for its own credential family.
This page is about the credentials; the ophthalmic technician career guide covers the role itself — the duties, the settings and the routes in.
COA vs COT vs COMT: the core certification ladder
The three core levels share one framework — apply, test, keep the credential current — and differ in the routes in, the exams and the renewal workload.
| COA | COT | COMT | |
|---|---|---|---|
| Full name | Certified Ophthalmic Assistant | Certified Ophthalmic Technician | Certified Ophthalmic Medical Technologist |
| Multiple-choice exam | 200 questions, 180 minutes | 200 questions, 180 minutes | 190 questions, 180 minutes |
| Skills testing | None | COT Skill Evaluation, 120 minutes | COT Skill Evaluation plus a 60-minute Performance Test |
| Window to finish | Single exam | Both parts within 24 months of application approval | All parts within 36 months of application approval |
| Renewal cycle | 36 months | 36 months | 36 months |
| Renewal by CE | 18 credits | 27 credits | 36 credits |
The COA is a single exam taken at Pearson VUE test centers, with no separate skills component.
The COT adds the Skill Evaluation — 120 minutes, currently computer-simulated and run over Zoom with an online proctor — and both COT parts must be passed within 24 months of application approval.
The COMT swaps in a 190-question multiple-choice exam, keeps the Skill Evaluation and adds a 60-minute Performance Test, all to be finished within 36 months of approval.
A current COT who moves up to the COMT does not repeat the Skill Evaluation; the Performance Test is the new piece.
Which level fits depends on where you are starting from: a graduate of an accredited program can test without logging work hours, while the experience routes convert supervised hours and prior certification into eligibility.
IJCAHPO specialty credentials
Alongside the core ladder, IJCAHPO's specialty list covers surgical assisting (OSA), diagnostic ophthalmic sonography (CDOS), ophthalmic ultrasound biometry (ROUB), retina (CRT), the corporate setting (CCOA, aimed at industry employees) and scribing (OSC).
IJCAHPO describes the OSA specialty certification as covering the procedures and instrumentation needed to assist in ophthalmic surgical suites.
The ROUB credential is for allied ophthalmic personnel who perform A-scan biometry.
There are also certificates of completion in contact lens fitting, low vision, visual fields and OSP, and IJCAHPO lists a Certified Refractionist certificate as coming soon.
The Ophthalmic Scribe Certification (OSC) works differently from the core exams.
It is an open-resource online exam of 125 questions spanning ten content areas, from electronic health records and history taking to abbreviations, anatomy, instruments, terminology, pharmacology and patient services.
Its eligibility pathways are recommended rather than required.
- A current IJCAHPO certification.
- A 1-year scribe certificate or 2-year scribe associate degree earned within the previous 12 months.
- 1,000 hours in the previous 12 months under an ophthalmologist's direct supervision as a scribe, front-office staffer or non-certified ophthalmic assistant or technician.
The OSC is valid for three years and renews only by passing the online exam again — there is no continuing-education route.
Our research found no fixed OSC fee: the price varies with your IJCAHPO certification, ATPO membership or the sponsoring ophthalmologist's society memberships, and it is shown only in the IJCAHPO store.
One boundary matters in optometry settings: the OSC is designed around scribing for an ophthalmologist, IJCAHPO offers no scribe credential aimed at optometry practices, and the AOA has no separate scribe certification — chairside scribing appears as a task inside the CPOT outline instead.
Eligibility routes for the COA, COT and COMT
IJCAHPO writes a separate list of eligibility pathways for each level, and the routes mix three ingredients: graduation from an accredited program, supervised work hours and a prior credential.
COA — Certified Ophthalmic Assistant.
- A1, the program route — graduate of an ICA-accredited clinical assistant program, with no work hours needed.
- A2, distance learning plus hours — graduate of an ICA-accredited non-clinical assistant program (including distance learning) plus 500 hours under an ophthalmologist within 12 months.
- A3, the work route — a high school diploma, an approved independent study course (JCAT or the American Academy of Ophthalmology's Ophthalmic Medical Assisting course) and 1,000 hours employed under an ophthalmologist within 12 months.
IJCAHPO sets no minimum age, but a high school diploma or equivalent is required before applying for the COA.
COT — Certified Ophthalmic Technician.
- T1, the program route — graduate of an ICA-accredited technician-level program, with no work hours needed.
- T2, COA plus hours — a current COA, 2,000 hours working as a COA under an ophthalmologist within the previous 24 months, and 12 IJCAHPO CE credits.
- T3 — a current Certified Orthoptist.
- T4, the fast track — a current COA with 6,000 hours of non-certified work under an ophthalmologist.
COMT — Certified Ophthalmic Medical Technologist.
- An ICA-accredited medical technologist program plus two years of college, with no work hours needed.
- The same program with less college, plus 4,000 hours under an ophthalmologist.
- A current COT with 6,000 hours as a COT within the previous 60 months.
- A current orthoptist with 4,000 hours.
- The COT fast track — 3,000 hours as a COT plus 6,000 non-certified hours.
One ingredient sits across the COA, COT and COMT routes: an ophthalmologist's signature.
IJCAHPO requires a sponsoring ophthalmologist to sign the application for the COA, COT and COMT, and words the work-experience hours as under the supervision of an ophthalmologist.
Work done only for an optometrist is not named as qualifying in those criteria.
If your hours sit in an optometry practice, treat it as an open question rather than a closed door, and ask IJCAHPO directly how your experience is treated before you plan around a level.

IJCAHPO exam fees
IJCAHPO publishes its exam fees in a fee table inside its criteria handbook, and that page carries no date — so read the figures below as what IJCAHPO lists, and confirm before you pay.
For the COA, the table lists $300 to sit the exam, with a first retest at $250 and a second retest at $150.
The COT fee is $325, covering one multiple-choice exam attempt and one skill attempt.
The same table lists separate retest fees for the COT, and fees for the COMT exam and its performance test.
There is a cheaper dry run at the COA level: IJCAHPO sells a practice exam at a reduced fee, and if you pass it, it can count as your real attempt once you pay the balance within 30 days.
The fee table is undated
Recertification: keeping a credential active
Every IJCAHPO certification is valid for 36 months, and renewal runs on that clock.
The continuing-education route takes 18 IJCAHPO credits for the COA (and its corporate cousin, the CCOA), 27 for the COT and 36 for the COMT, on an application signed by a sponsoring ophthalmologist.
COT and COMT holders have a second option: recertify by retaking only the multiple-choice exam instead of earning CE.
Two credentials cannot renew by CE at all — the OSC and the CRT renew only by retesting.
The CME rules differ by level: COAs and COTs can no longer use AMA/CMA Category 1 CME for recertification, and since August 1, 2024, COMTs may count up to 12 AMA/CMA Category 1 CME credits.
Recertification costs $125, and an application made within 12 months after the recertification date adds an $85 late fee.
Fall further behind and the credential is revoked once it is more than six months past the recertification date — with a one-time reinstatement option as the way back.
One wrinkle worth naming: IJCAHPO's fee table allows a late application within 12 months of the recertification date, while its recertification materials describe revocation at six months past it.
Our sources do not reconcile the two, so confirm your exact dates with IJCAHPO before you count on either window.
Career value in OD and OD-MD practices
The ladder is built for progression: a tech can certify at the COA, log hours as a COA and move up to the COT, then take the COT-to-COMT route once the hours are there.
In ophthalmology practices and OD-MD groups, that structure lines up with the clinical team, because the eligibility hours and the sponsor's signature are both written around an ophthalmologist.
For technicians whose hours sit in an optometry practice, the criteria matter in two places: the work-experience routes count hours under the supervision of an ophthalmologist, and the application needs an ophthalmologist's signature.
Work done only for an optometrist is not named as qualifying in those criteria, so the certification plan for an OD-practice tech runs through a question to IJCAHPO, not around it.
The code of ethics for IJCAHPO's core certificants also names settings: it says they provide technical ophthalmic services only in the office of their sponsoring ophthalmologist or physician, a medical clinic or another medical facility.
The code does not define whether an optometry practice counts as a medical clinic, so that is one more point to put to IJCAHPO directly.
For practices, that signature requirement is the structural fact to weigh before a job description promises a certification ladder — the application routes through an ophthalmologist, and IJCAHPO's criteria decide which hours qualify.
On the optometric side of eye care, the counterpart system is the AOA's paraoptometric family — the CPO, CPOA, CPOT and CPOC — developed and administered by the AOA's Commission on Paraoptometric Certification.
Whichever system a tech pursues, the credential is separate from the job: an employer writes its own ophthalmic technician role, and the letters behind a name come from the certifying body's own criteria.
If you are weighing a move between settings, the hiring guides for eye care practices show the employer side — what practices ask for and how they staff.
