- The COMS is awarded by ACVREP; a current pass rate and passing threshold were not verified from official sources reviewed.
- The exam has 150 multiple-choice and multiple-select items across ten published domains.
- Mobility Skills and Strategies carries 17% (26 questions), the heaviest single domain.
- The handbook's timer wording is internally inconsistent: "Up to three (3.5) hours." Confirm before test day.
Why You Won't Find a Verified COMS Pass Rate Here
Search for the pass rate of the Certified Orientation and Mobility Specialist exam and you will find confident-sounding percentages on forums, prep sites and social media posts. This article takes a different approach: it reports what can be traced to the credentialing body's published materials and says plainly where the record is silent.
The Academy for Certification of Vision Rehabilitation and Education Professionals (ACVREP) administers the COMS credential. In the official certification page and the linked COMS Certification Handbook that were reviewed for this article, a current pass rate was not verified. The same is true of the current passing threshold and of the split between scored and unscored items. Rather than invent a figure to satisfy a search query, this guide shows you how to reason about difficulty using the information that is published.
If you are comparing this credential with others and want a broader sense of challenge, our complete difficulty guide for the COMS exam walks through the content load in more depth, and the COMS passing score article tracks what is and is not confirmed about scoring.
What Has Actually Been Verified About the Exam
Here is the factual footing for everything else in this article. These details come from the official ACVREP certification page and the COMS Certification Handbook it links:
- Certifying body: ACVREP.
- Credential: Certified Orientation and Mobility Specialist. This is a vision-rehabilitation credential for professionals who teach safe, independent travel to people who are blind or visually impaired. It is not an ophthalmic, orthoptic or occupational-therapy examination.
- Format: 150 multiple-choice and multiple-select items.
- Content focus: Entry-level principles and their application with preschool, school-aged and adult individuals who are blind or visually impaired.
- Handbook currency: The handbook's visible revision date is March 14, 2024. Its examination section states it was updated in January 2023 and implemented February 1, 2023. Current linking was verified September 29, 2026.
- Blueprint: Ten examination domains with published percentage weights and question counts, covered below.
One caution worth repeating: file metadata on a downloaded document is not evidence of a revised 2026 blueprint. Until ACVREP publishes a new examination section, the published blueprint described here is the one to study against. For a domain-by-domain walkthrough, see our complete guide to all ten COMS content areas.
The Three-Hour Versus Three-and-a-Half-Hour Timer Question
The handbook's wording on exam time is internally inconsistent. It prints: "Up to three (3.5) hours is allowed." The spelled-out number says three; the parenthetical figure says three and a half. The sources reviewed do not resolve which is correct, so the exact timer remains unverified.
This matters for pacing. With 150 items, the difference between 180 minutes and 210 minutes changes your per-question budget meaningfully. Rather than guess, plan conservatively and confirm the real limit with ACVREP or in your testing confirmation materials before exam day.
| Timer Reading | Total Minutes | Approx. Minutes per Item (150 items) |
|---|---|---|
| Three hours | 180 | 1.2 |
| Three and a half hours | 210 | 1.4 |
Reading the Blueprint as a Difficulty Signal
Without an official pass rate, the blueprint is the best objective instrument you have. It tells you where the 150 questions live. The published weights total 100% and the published question counts total 150. Percentages are rounded published figures, so do not expect every percentage to multiply out to a whole number of questions; rely on the published counts.
| Domain | Weight | Questions |
|---|---|---|
| 1. Professional Information and Resources and Teaching and Learning in O&M | 11% | 16 |
| 2. Relevant Medical Information | 8% | 12 |
| 3. O&M Assessment, Program Design and Delivery and Environmental Assessment and Modification | 15% | 23 |
| 4. O&M-related Concepts | 8% | 12 |
| 5. Orientation Skills and Strategies | 12% | 18 |
| 6. Mobility Skills and Strategies | 17% | 26 |
| 7. Use of Senses | 8% | 12 |
| 8. Clients with Additional Disabilities and Diverse Clients | 9% | 13 |
| 9. Psychosocial Aspects of Blindness and Low Vision | 5% | 8 |
| 10. Code of Ethics | 7% | 10 |
Two observations follow directly. First, Domains 3, 5 and 6 together account for 67 of the 150 questions, which is the practical core of the exam: assessment and program design, orientation, and mobility. Second, the handbook combines some body-of-knowledge areas into these ten examination groups, so do not confuse the separate body-of-knowledge headings with the exam's ten domains when you plan your study.
Where Candidates Tend to Lose Ground
Because no pass-rate data was verified, the following is analysis of the blueprint rather than a statistical finding. The areas below combine heavy weighting with content that rewards applied judgment over memorization.
Domain 6: Mobility Skills and Strategies (17%, 26 questions)
The largest domain, and the one where scenario questions are most likely to test whether you can choose a safe instructional response.
- Match techniques to client needs, travel environments and safety considerations.
- Expect application items framed around preschool, school-aged and adult learners.
- Think in terms of instructional decisions, not just technique names.
Domain 3: Assessment, Program Design and Environmental Modification (15%, 23 questions)
This domain bundles three competencies into one heavily weighted group, which makes it easy to under-prepare.
- Connect assessment findings to program goals and delivery choices.
- Understand how environments can be analyzed and modified to support safe travel.
- Practice reading a case description and identifying the most defensible next step.
Domain 2: Relevant Medical Information (8%, 12 questions)
O&M specialists are not clinicians, but they must understand how visual conditions affect functional travel. Candidates from education backgrounds sometimes find this the least familiar domain.
- Link eye conditions and functional vision implications to instructional planning.
- Know the limits of professional scope when medical questions arise.
Domain 8: Clients with Additional Disabilities and Diverse Clients (9%, 13 questions)
Thirteen questions is not trivial. These items test adaptation and cultural responsiveness, and they reward flexible reasoning.
- Adapt instruction when a client has additional disabilities.
- Recognize how diversity shapes goals, communication and service delivery.
Key Takeaway
Do not treat the smaller domains as skippable. Psychosocial Aspects (8 questions) and Code of Ethics (10 questions) total 18 items, roughly the size of Domain 5. Because they are scenario-driven, they are also among the most winnable points for a well-prepared candidate.
How to Evaluate Any Pass-Rate Claim You Encounter
You will run into pass-rate numbers during your preparation. Use these questions to sort signal from noise:
- Who published it? A figure attributed to ACVREP should point to an ACVREP document or statement. A figure repeated on a blog with no source is not evidence.
- What period does it cover? The handbook's examination section was updated in January 2023 and implemented February 1, 2023, so results from before that change may describe a different form of the exam.
- Who is in the sample? First-time test-takers, repeat candidates and different preparation routes produce very different results. A single blended number hides this.
- Is it a pass rate or a self-report? Social media threads are self-selected; people who passed tend to post more than people who did not.
- Does it match the scoring rules? Since the passing threshold and scored/unscored split were not verified here, be skeptical of any claim that quotes a precise cut score without a source. Our passing score guide explains what is known and unknown.
The honest conclusion for 2026 is that the most reliable predictor of your outcome is your own performance on realistic practice material, not a population statistic.
A Domain-Sequenced Preparation Plan
The sequence below ties the schedule to this exam's blueprint rather than to generic study theory. It assumes roughly six weeks and should be stretched if your clinical or coursework background is thin in a given area. For a fuller roadmap, see the COMS study guide.
Build the heavy core: Domains 6 and 3
- Work through Mobility Skills and Strategies first: it is 26 questions and underpins much else.
- Pair it with Assessment, Program Design and Environmental Modification (23 questions) so that technique choices connect to assessment findings.
Orientation and sensory foundations: Domains 5, 4 and 7
- Orientation Skills and Strategies (18 questions) builds directly on mobility content.
- Cover O&M-related Concepts and Use of Senses (12 questions each) while the instructional context is fresh.
Knowledge-heavy domains: Domains 2 and 1
- Relevant Medical Information (12 questions): focus on functional implications for travel.
- Professional Information and Resources and Teaching and Learning in O&M (16 questions).
Judgment domains: Domains 8, 9 and 10
- Clients with Additional Disabilities and Diverse Clients, Psychosocial Aspects, and Code of Ethics together total 31 questions.
- Practice reasoning from scenarios, choosing the response that is safest and most professionally defensible.
Full-length simulation and gap repair
- Sit a 150-item practice run under the stricter 180-minute assumption.
- Review misses by domain and revisit the weakest one or two.

Frequently Asked Questions
A current pass rate was not verified from the ACVREP certification page or the COMS Certification Handbook reviewed for this article. Treat any uncited percentage as unverified, and contact ACVREP if you need an official statistic.
The handbook specifies 150 multiple-choice and multiple-select items covering entry-level principles and application with preschool, school-aged and adult individuals who are blind or visually impaired. The items are distributed across ten examination domains.
This is not settled by the sources reviewed. The handbook prints "Up to three (3.5) hours is allowed," which conflicts with itself. Confirm the exact limit with ACVREP before your test date and practice at the shorter 180-minute pace to be safe.
Domain 6, Mobility Skills and Strategies, at 17% or 26 of the 150 questions. Domain 3 follows at 15% (23 questions), then Domain 5 at 12% (18 questions).
The handbook's visible revision date is March 14, 2024, and its examination section says it was updated in January 2023 and implemented February 1, 2023. File metadata is not evidence of a revised 2026 blueprint, so study against the published ten-domain structure and recheck the ACVREP page before you test.
