- PAM is NBEO's Part II exam: 350 questions in two 175-question sessions, seven testing hours in one day.
- Normal Health / Disease / Trauma carries 60-70% of the content; Refractive / Sensory / Oculomotor carries 30-40%.
- Treatment / Management is the heaviest task dimension at 40-57%, so study what to do, not just what it is.
- NBEO scores run 100-900, with scores above 300 passing; scores are equated across forms, not curved.
What You Are Actually Preparing For
The Patient Assessment & Management exam, known as PAM, is Part II of the National Board of Examiners in Optometry (NBEO) licensure examination sequence. It is not a specialty badge or an optional credential. It is a full entry-to-profession licensure examination, and it is a separate exam from the standalone TMOD pathway and from Part III PEPS. If you want background on the name itself, see our explainers on what PAM is and what PAM stands for.
That framing matters for how you study. PAM is designed to test whether a new optometrist can assess a patient and manage the case safely, not whether you can recite isolated facts. The questions are built around clinical scenarios, many of them image-intensive, and the heaviest weighting rewards candidates who know what to do next. If you have been preparing as though this were a basic-science recall test, adjust early. The PAM practice test on this site is built around that scenario-driven style so you can calibrate quickly.
Exam Mechanics: Format, Timing and Test-Day Rules
Knowing the mechanics ahead of time removes avoidable stress on exam day. Here are the confirmed structural facts from NBEO's published materials.
| Feature | PAM Detail |
|---|---|
| Total questions | 350, delivered as two sessions of 175 |
| Testing time | Seven hours in one day, split into two 3.5-hour sessions |
| Extra morning time | 15 additional minutes for the tutorial and non-disclosure agreement (not question-timer minutes) |
| Break | Optional, up to 45 minutes between sessions |
| TMOD content | Approximately 120 TMOD items are embedded within the 350, not added to them |
| Pass/fail decisions | Overall PAM and TMOD are decided separately |
| Testing provider | Pearson VUE centers in the USA, Puerto Rico and Canada |
| Reference materials | Closed-book; on-screen basic calculator, searchable generic/trade drug equivalence list, abbreviation list, and a supplied scratch booklet |
Rules that affect strategy
- No going back across the break. Once you finish Session 1 and take the inter-session break, you cannot revisit those questions. Flag and review within the session, but do your final checks before you submit it.
- Unscheduled breaks do not stop the clock. Use the scheduled optional break for food, water and a reset, and treat the rest of each session as continuous.
- Identification is strict. You need two current signed physical IDs, at least one of them a government photo ID, matching your registration exactly.
- The drug list is a tool, not a syllabus. The searchable generic/trade equivalence list helps with name matching, but it does not define what pharmacology you must know. You still need to understand mechanisms, indications, adverse effects and when to choose one agent over another.
Reading the Blueprint: Two Domains, Four Task Dimensions
NBEO publishes two documents that candidates often conflate: the Part II PAM Content Outline and the Part II Content Matrix. They describe the same exam from two angles, and understanding the difference helps you allocate time sensibly. For a deeper walkthrough, see our complete guide to the PAM content areas.
The two content domains
| Domain | Weight |
|---|---|
| Refractive / Sensory Processes / Oculomotor Processes | 30-40% |
| Normal Health / Disease / Trauma | 60-70% |
The task dimensions in the matrix
The matrix cross-classifies the same content by the kind of thinking each question demands. These are not four more domains stacked on top of the two above. They intersect with them.
| Task dimension | Range |
|---|---|
| Clinical Correlation of Basic Science Principles | 11-17% |
| Diagnosis | 26-34% |
| Treatment / Management | 40-57% |
| Legal Issues / Ethics / Public Health | 4-10% |
Clinical presentation, meaning history, signs and symptoms, is assessed inside the cases rather than carrying its own percentage. In practice, that means every case stem is doing double duty: you must extract the relevant findings and then decide what they imply and what to do about them.
Key Takeaway
Treatment / Management is the largest task dimension at 40-57%. For every condition you study, finish the loop: how it presents, how you confirm it, what you do, how you follow up, and when you refer or co-manage.
Domain 1 Study Priorities: Refractive, Sensory and Oculomotor Processes
At 30-40% of the exam, this domain is smaller than the disease domain, but it is also where many candidates can bank dependable points because the reasoning is more systematic. The outline uses the wording "Accommodative / Vergence / Oculomotor Anomalies," so make sure your notes cover that grouping explicitly.
Refractive, Sensory and Oculomotor Processes
This domain rewards clean, repeatable clinical reasoning. Build fluency in the following areas:
- Refractive error analysis, including how findings translate into a prescribing decision, not just a number
- Accommodative, vergence and oculomotor anomalies: recognizing the pattern from symptoms and test results, then selecting the right management path
- Sensory processes, including how disruption of binocular function or visual processing shows up in a case
- Interpreting a presentation that spans refractive and binocular findings at once, since cases rarely stay in one lane
Because the calculator on the exam is a basic on-screen tool, practice doing prism, lens power and vergence-style calculations efficiently and with sanity checks. A result that is off by a factor of ten should feel wrong before you click.
Domain 2 Study Priorities: Normal Health, Disease and Trauma
This is the bulk of the exam: 60-70%. It is also the domain where the Treatment / Management dimension bites hardest, because disease and trauma cases almost always end with a decision about therapy, monitoring or referral.
Normal Health, Disease and Trauma
Think in presentations rather than in textbook chapters. For each condition, be able to move through the full clinical arc:
- Recognize the condition from a history, a set of signs and often an image
- Distinguish it from look-alikes with the most discriminating finding or test
- Select initial management, including pharmacologic choices and the reasoning behind them
- Decide follow-up timing, escalation triggers and whether co-management or referral is appropriate
- Recognize urgent and emergent situations, including trauma, where the first correct action matters most
Do not neglect the smaller content tied to the matrix. Legal issues, ethics and public health are only 4-10%, but they are some of the most learnable points on the exam. A few dedicated sessions on scope-of-practice reasoning, informed consent, reporting obligations and public-health principles can convert directly into score.
Mastering Case-Based and Multiple-Response Questions
PAM's item style is distinctive, and unfamiliarity with it costs points that content knowledge alone would have earned.
Image-intensive patient cases
Patient cases typically carry three to six associated items, and the response lists can run from three to ten options. That means one case can swing several questions, so reading the stem and any image carefully the first time pays off repeatedly. Build a habit of narrating the image to yourself before looking at the options: what structure, what finding, what laterality, what severity.
Single-answer versus multiple-response
The exam uses both single-answer and multiple-response items. On multiple-response questions, up to four correct selections can be required, and credit requires all and only the requested correct options. There is no partial credit for getting three of four.
- Read the instruction line first so you know exactly how many selections the item wants.
- Evaluate each option independently as true or false for this patient, rather than ranking them against each other.
- If you can justify only three of a required four, reread the stem for a clue you missed rather than guessing a fourth.
When you drill, make sure your practice questions include multiple-response formats. Our full-length PAM practice questions are a good place to build that habit, and the one-page PAM cheat sheet is useful for last-pass review of high-yield facts.
Scoring, Pass Rates and What They Do Not Tell You
NBEO reports Part II scores on a 100-900 scale, and its Scoring & Reporting page states that scores above 300 pass. Scores are equated across forms rather than curved, which means your result reflects your performance against a fixed standard, not your rank against the other people who tested that day. For a focused breakdown, see our guide to the PAM passing score.
Interpreting the pass-rate numbers carefully
Two published figures are worth knowing, but they measure different things and should not be blended into a trend:
- UC Berkeley and Ferris State both report an 89.4% national first-time Part II PAM pass rate for academic year 2025-2026 (September 1-August 31). These are university publications of NBEO outcomes, and their first-time population includes candidates regardless of graduation status.
- NBEO's own Institutional Yearly Performance Report for October 1, 2024-September 30, 2025, hosted by ASCO, shows an 87.96% Part II first-time pass rate for a cohort of 1,628 qualifying U.S. graduates. That cohort includes only graduates who attempted all three NBEO parts at least once.
Because the populations and periods differ, these two numbers are not directly comparable, and neither should be read as a prediction of your personal result. The practical takeaway is that most first-time candidates pass, but a meaningful minority do not. Our PAM pass rate analysis and difficulty guide unpack the context in more detail.
Registration, Fees and Eligibility
The process runs through two organizations: you register and pay through NBEO, then schedule your appointment with Pearson VUE. Do not assume that paying NBEO books you a seat.
| Item | Detail |
|---|---|
| Examination fee | USD $1,490 for administrations beginning August 2026 |
| Late registration | Adds $400 |
| Optional practice databank | $199 for one month; $149 for an additional month, subject to registration and administration-date conditions |
The databank charges are preparation costs, separate from the examination fee. For the full financial picture, including how these pieces add up, read our PAM cost breakdown, and check the PAM exam dates guide for scheduling logistics.
Who can sit for it
Student eligibility begins in the academic year of graduation from an ACOE program with Accredited, Accredited with Conditions or Preliminary Approval status, with institutional confirmation. Graduates of Accredited or Accredited with Conditions programs are eligible. Other candidates need direct sponsorship from a qualifying optometric program or a state optometry licensure board. The details are laid out in our PAM requirements guide, but always confirm against NBEO's current eligibility policy before you register.
A Domain-Weighted Study Sequence
Generic study techniques will only take you so far, so here is a sequence tied to PAM's actual weighting. Adjust the length to your calendar; the logic is what matters: spend the most time where the exam spends the most points, and put full-length simulations at the end.
Diagnose and Map
- Take a baseline practice set and sort misses by domain and by task dimension
- Read the current Content Outline and Content Matrix on optometry.org and annotate your weak areas
- Review legal, ethics and public-health points early while they are quick wins
Normal Health / Disease / Trauma
- Spend the largest block of time here, since it is 60-70% of the exam
- Study by presentation, finishing each condition with management and follow-up
- Practice with images and multi-item cases
Refractive / Sensory / Oculomotor
- Drill calculation-driven items with a basic calculator only
- Work accommodative, vergence and oculomotor patterns until recognition is fast
Simulate and Refine
- Complete at least two full-length, two-session timed runs
- Practice multiple-response questions and the no-return rule between sessions
- Use your error log to patch the last gaps rather than starting new material
If you retake or are repeating a weak area, keep one habit throughout: maintain an error log that records not only the right answer but why you chose the wrong one. Most missed items on PAM trace back to a misread stem or a skipped management step, not an unknown fact.
Choosing Practice Resources Wisely
NBEO offers an optional Part II PAM/TMOD Practice Databank containing NBEO-owned questions, administered by Test Run, an independent third-party organization. Purchasing or completing it does not guarantee a pass, and we have not accessed the paid bank, so we cannot describe its contents beyond what NBEO publishes. Other commercial and school-based resources exist; evaluate any of them on three criteria:
- Format fidelity: Does it include image-based cases with several linked items, and multiple-response questions requiring all and only the correct options?
- Management depth: Do explanations cover what to do and why, not just the diagnosis?
- Alignment with the current outline: Check that topics map to the present Content Outline rather than an older framework.
Be wary of anything claiming to be recalled exam content. NBEO prohibits distributing recalled items, and relying on them is both a policy risk and a poor way to learn. Build understanding from legitimate sources, then test it with our PAM practice exam and similar tools. If you are weighing whether the whole effort pays off for your career, our analyses of earnings and return on investment can help frame the decision.
Key Takeaway
Verify everything time-sensitive against NBEO directly. The Content Outline, Content Matrix and Test Day Instructions currently linked on optometry.org carry May 2026 filename dates, and fees and policies can change, so check the official pages before you commit to a plan.
Frequently Asked Questions
The exam has 350 questions delivered in two sessions of 175, with seven testing hours in one day split into two 3.5-hour sessions. The morning adds 15 minutes for the tutorial and non-disclosure agreement, and an optional break of up to 45 minutes separates the sessions.
NBEO reports scores on a 100-900 scale and states that scores above 300 pass. Scores are equated across exam forms rather than curved. Overall PAM and TMOD receive separate pass/fail decisions.
Normal Health / Disease / Trauma, at 60-70% of the content. Within it, prioritize management decisions, since Treatment / Management is the largest task dimension at 40-57%. Refractive / Sensory Processes / Oculomotor Processes makes up the remaining 30-40%.
No. Session 1 cannot be revisited after the inter-session break, so complete your flagged-question review before you submit the session. Unscheduled breaks also do not pause the clock.
No. The optional databank, administered by Test Run, contains NBEO-owned questions and costs $199 for one month, but NBEO does not claim that purchasing or completing it guarantees a passing result. Treat it as one preparation tool among several.
