What PAM Actually Is
PAM stands for Patient Assessment and Management. It is Part II of the National Board of Examiners in Optometry (NBEO) examination sequence, the full entry-to-profession licensure examination that tests whether a candidate can reason through real patient presentations: gathering history, interpreting signs and findings, reaching a diagnosis and choosing appropriate management.
If you landed here searching for a definition, it helps to be precise, because the acronym is shared by unrelated credentials in other fields. On this site, PAM means exactly one thing: the NBEO Part II Patient Assessment and Management examination. It is not a standalone TMOD registration, not Part III PEPS, and not an independent board certification. If you want shorter definitional pages, see What Does PAM Stand For? and PAM Meaning.
Where PAM Fits in the NBEO Sequence
NBEO structures its national examination in parts. PAM is the second, and it is the part most associated with clinical reasoning rather than basic science recall or hands-on skills demonstration. The legacy Part Equivalency page at nbeo.org serves as an identity and history anchor for how the parts map to one another, but the current blueprint lives in the materials linked from optometry.org, including the Part II PAM Content Outline, the Part II Content Matrix and the Part II PAM Test Day Instructions.
For a plain-language overview of the credential and its role in becoming licensed, the companion page What Is PAM Certification? covers the terminology, while this article focuses on the exam itself: what it contains, how it is delivered and how it is scored.
Exam Format and Test-Day Mechanics
PAM is a single-day, closed-book examination delivered at Pearson VUE test centers in the USA, Puerto Rico and Canada. You register and pay through NBEO, then schedule your appointment with Pearson VUE.
| Feature | PAM Detail |
|---|---|
| Total questions | 350, split into two sessions of 175 |
| Testing time | Seven hours in one day, as two 3.5-hour sessions |
| Morning add-on | 15 additional minutes for the tutorial and non-disclosure agreement (not question-timer time) |
| Break | Optional, up to 45 minutes between sessions |
| Provider | Pearson VUE centers in the USA, Puerto Rico and Canada |
| Fee | USD $1,490 for administrations beginning August 2026; late registration adds $400 |
| Reference materials | Closed book |
Tools and rules you should know in advance
- On-screen resources: a basic calculator, a searchable generic/trade drug equivalence list, an abbreviation list and a supplied scratch booklet. The drug list is a lookup aid, not an exhaustive syllabus, so do not treat it as a study outline.
- No revisiting Session 1: once the inter-session break begins, you cannot return to Session 1 questions. Your pacing and review habits must fit that constraint.
- Unscheduled breaks: stepping away outside the optional break does not stop the clock.
- Identification: two current signed physical IDs, with at least one a government photo ID, and the names must match your registration.
The Two Content Areas
The Part II PAM Content Outline organizes the exam into two top-level areas. These are the two domains you will see referenced throughout this site, and the full breakdown is in PAM Exam Domains 2026: Complete Guide to All 2 Content Areas.
Domain 1: Refractive / Sensory Processes / Oculomotor Processes (30-40%)
This area covers the optical, sensory and motor-coordination side of visual function. Candidates must move comfortably between measurement, interpretation and management.
- Refractive conditions and how they are assessed and corrected
- Sensory processing and visual-function findings
- Accommodative / Vergence / Oculomotor Anomalies (the outline's wording is the controlling phrasing; the matrix words it slightly differently)
Domain 2: Normal Health / Disease / Trauma (60-70%)
This is the larger area and the heart of the exam. It spans normal ocular and systemic health, the full range of disease presentations and traumatic conditions.
- Recognizing the difference between normal variation and pathology
- Diagnosing and managing ocular disease from presenting history, signs and symptoms
- Evaluating and managing trauma presentations
Because Normal Health / Disease / Trauma carries 60-70% of the content, it is where most of your preparation hours belong, even though Domain 1 is far from trivial at 30-40%. The percentages are ranges, so do not assume any single form lands on a fixed split.
The Task Matrix: How Content Is Cross-Classified
Separate from the two domains, NBEO publishes a Part II Content Matrix (the linked file is dated May 4, 2026) that cross-classifies the same content by the type of task a question asks of you. These are intersecting dimensions, not four additional domains stacked on top of the two above, and the ranges are preserved here exactly as published.
| Task Dimension | Share of Content |
|---|---|
| Clinical Correlation of Basic Science Principles | 11-17% |
| Diagnosis | 26-34% |
| Treatment / Management | 40-57% |
| Legal Issues / Ethics / Public Health | 4-10% |
Clinical Presentation (history, signs and symptoms) is assessed within the cases themselves and does not carry a separate percentage. The practical reading of this matrix: Treatment / Management is the single largest task type, so memorizing disease features without knowing what to do about them leaves a large share of the exam under-prepared. A candidate who can name a condition but cannot choose, sequence and justify a management plan will struggle.
Key Takeaway
Prepare by task as well as by topic. For every condition you study, practice the full chain: presentation, diagnosis, then treatment or management, plus any legal, ethical or public health angle the case raises.
Question Style: Image-Intensive Cases
PAM is built around clinical cases, many of them image-intensive. A single patient case generally carries three to six associated items, and individual items offer three to ten response options. That structure rewards candidates who can hold a patient story in mind while answering several questions about it in sequence.
- Single-answer items: choose the one best response.
- Multiple-response items: select all that apply. Up to four correct selections can be required, and credit requires all and only the requested correct options. Partial selections do not earn credit.
- Image interpretation: expect to interpret clinical imagery as part of reaching the diagnosis or the management decision.
The all-or-nothing multiple-response rule changes how you should practice. Guessing a "close enough" set of options is not enough, so rehearse committing to complete, justified answer sets. Questions about how hard this format feels in practice are covered in How Hard Is the PAM Exam? Complete Difficulty Guide 2026.
The TMOD Component Inside PAM
Roughly 120 Treatment and Management of Ocular Disease (TMOD) items are embedded within the 350 PAM questions. They are not added on top of the 350. NBEO describes the count as approximate, and the matrix footnote's "120" figure is qualified by the outline and program description, so treat it as an approximation.
The key consequence: overall PAM and TMOD receive separate pass/fail decisions. Taking the full PAM examination is different from registering for standalone TMOD, which is a separate pathway and not the exam this site covers. Because those embedded TMOD items are woven through the same cases, there is no separate "TMOD section" to cram; strong disease-management reasoning serves both outcomes at once.
Eligibility, Registration and Fees
Who can sit for PAM
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. NBEO's eligibility section was last updated May 18, 2025, so confirm current terms before you apply. A fuller walkthrough is in PAM Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Registration flow and money
- Register and pay through NBEO.
- Receive authorization, then schedule your appointment with Pearson VUE.
- Bring matching IDs on test day (two signed physical IDs, at least one government photo ID).
The exam fee is USD $1,490 for administrations beginning August 2026, and late registration adds $400. NBEO also offers an optional Part II PAM/TMOD Practice Databank, administered by an independent third party, Test Run. It costs $199 for one month, with a $149 additional-month renewal subject to registration and administration-date conditions. Those are preparation charges, separate from the exam fee, and purchasing or completing the databank does not guarantee a pass. A complete cost picture, including what to budget around the fee, is in PAM Certification Cost 2026: Complete Pricing Breakdown.
Scoring and Pass Rates
NBEO's current Scoring and Reporting page uses a 100-900 scale and states that scores above 300 pass. That is the exact boundary wording, and it is not translated here into a raw percentage of questions answered correctly. Scores are equated across forms rather than curved, which means your result reflects performance against a consistent standard instead of how your cohort happened to do. For more on interpreting your number, see PAM Passing Score 2026: Exactly What You Need to Pass.
What the published pass-rate data says
Two separate figures circulate, and they should not be blended:
| Source | Figure | Population and Period |
|---|---|---|
| UC Berkeley and Ferris State publications | 89.4% Part II first-time pass rate | National first-time candidates, academic year 2025-2026 (September 1-August 31), regardless of graduation status |
| NBEO Institutional Yearly Performance Report (hosted by ASCO) | 87.96% Part II first-time pass rate | 1,628 qualifying U.S. graduates, October 1, 2024-September 30, 2025, limited to graduates who attempted all three NBEO parts at least once |
These cover different populations and different time windows, so they are not a trend line and should not be pooled or compared as if one improved on the other. The 89.4% figure comes from university publications of NBEO outcomes rather than an issuer-hosted national dataset. Older university rows disagree with one another, so no combined historical trend is drawn here. For the fuller discussion, see PAM Pass Rate 2026: What the Data Shows.
Who Needs PAM and Who Cares About It
PAM is a gateway for candidates entering the optometry profession. Its audience is optometry students approaching graduation and eligible sponsored candidates, and the audience that "cares" about the result is state optometry licensing boards, which use national examination results as part of the licensure process. Because boards can add their own acceptance conditions, check the requirements of the state where you plan to practice.
Employers in optometry practices generally expect licensed practitioners, so PAM matters indirectly: it is one of the steps standing between graduation and being licensed to practice. It is not a credential you list to qualify for a specialty or to compete for a separate certified role. If your questions are about careers after licensure, the pages on PAM Jobs and PAM Salary Guide 2026: Complete Earnings Analysis discuss that context, and Is the PAM Certification Worth It? Complete ROI Analysis 2026 weighs the investment.
Sequencing Your Preparation Around PAM's Structure
You do not need a generic study system here; you need a sequence that mirrors how PAM weights its content. The timeline below ties each stage to a specific area of the blueprint.
Domain 1 foundation
- Review refractive, sensory and oculomotor material, including Accommodative / Vergence / Oculomotor Anomalies
- Do this first: it is the smaller 30-40% area and builds quick confidence
Normal Health / Disease / Trauma core
- Spend the largest block of time here (60-70% of content)
- For each condition, rehearse presentation, diagnosis, then treatment / management
Case and image practice
- Work multi-question cases with three to six items each
- Practice multiple-response items where only the complete correct set earns credit
Full-length simulation
- Rehearse two 175-question sessions with no returning to Session 1
- Practice with the on-screen calculator, drug equivalence list and abbreviation tools in mind
Do not neglect the 4-10% Legal Issues / Ethics / Public Health slice; it is small but predictable and easy to under-study. For a fuller plan, see the PAM Study Guide 2026: How to Pass on Your First Attempt and the condensed PAM Cheat Sheet 2026: One-Page Review of Must-Know Facts. When you are ready to test yourself against realistic questions, try the PAM practice tests, and revisit the full practice question bank as your exam date approaches. Candidates who want structured guidance may also find the notes on PAM Training useful.
Frequently Asked Questions
PAM stands for Patient Assessment and Management. It is Part II of the National Board of Examiners in Optometry (NBEO) examination, a 350-question licensure examination focused on clinical reasoning with patient cases.
There are 350 questions 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 forms rather than curved, so the standard does not shift with how other candidates perform.
For the full Part II examination, no. Approximately 120 TMOD items are embedded within the 350 questions, and overall PAM and TMOD get separate pass/fail decisions. Standalone TMOD is a different registration pathway.
NBEO says scores do not expire. However, PAM is a licensure examination result rather than a renewable specialty certification, and individual state licensing boards can set their own conditions for accepting results.
