PAM Passing Score 2026: Exactly What You Need to Pass

The 100-900 Scale and the "Above 300" Rule

If you are preparing for the Patient Assessment & Management Exam (PAM), the single most important number on the NBEO side is the passing boundary. According to NBEO's current Scoring & Reporting page, Part II PAM results are reported on a 100-900 scale, and scores above 300 pass. That wording is deliberately retained here as NBEO states it. This article does not translate it into a raw percentage of questions answered correctly, because NBEO does not publish such a conversion, and any figure you see on a forum claiming "you need X% correct" is speculation rather than policy.

The PAM is the Part II examination of the National Board of Examiners in Optometry (NBEO). It is the full entry-to-profession licensure examination for the Patient Assessment and Management content area. It is not a standalone TMOD registration, not Part III PEPS, and not an independent board certification. If you are still orienting yourself on what the credential is, the overview at What Is PAM? covers the basics, and PAM Requirements 2026: Eligibility, Prerequisites & How to Qualify explains who may sit for it.

What the Passing Boundary Does and Does Not Tell You

A scaled score is not a percentage. The 100-900 range is a reporting scale, and the number 300 sits on that scale; it does not mean 300 of 900 points, one third of the questions, or any other simple fraction. Candidates who try to reverse-engineer a "number of questions I can miss" from the scale are building on sand, because NBEO does not release the conversion from raw performance to scaled score.

What the boundary does tell you is how the result is communicated: you receive a scaled score, and the pass/fail determination follows from whether that score is above the stated threshold. There is no published partial-credit band, no "conditional pass," and no section-by-section minimum that you must clear independently on the scale described in the sources used for this article.

Practical consequences of a scaled boundary

• You cannot game a question count. Because the conversion is not published, the only reliable strategy is broad, accurate command of the content.
• Every item is worth answering. There is no reason to leave a question blank when you can reason to a best answer, particularly on single-answer items.
• Practice-test percentages are directional only. A percentage on an unofficial question bank is not a predicted scaled score. Treat it as a signal about weak topics, not a forecast.

Equated, Not Curved: Why Form Difficulty Does Not Matter

NBEO states that scores are equated across forms. Equating is a statistical process that adjusts for small differences in difficulty between versions of the exam so that a given scaled score represents the same level of performance regardless of which form you drew. It is not a curve. A curve ranks you against the people sitting the exam around you; equating holds the standard constant.

For you, this has two practical implications. First, you are not competing with the other people in your Pearson VUE testing center. A strong cohort does not push the line up, and a weak one does not pull it down. Second, you should not spend mental energy trying to guess whether your form was "the hard one." The scale is designed so that doesn't change what a passing result represents.

Two Pass/Fail Decisions: PAM and Embedded TMOD

The 350-question PAM includes approximately 120 TMOD items that are embedded within the 350, not added on top of them. NBEO treats overall PAM and TMOD as separate pass/fail decisions. The source materials note that the content matrix footnote says 120 while the outline and program description qualify the count as approximate, so the safest wording is "approximately 120."

The takeaway is that you should not mentally collapse the exam into a single outcome. Because the TMOD component has its own decision, a candidate should prepare the TMOD-relevant material (the ocular-disease and treatment-oriented content that drives much of the exam) as deliberately as the rest. For a broader view of where each content area sits, see PAM Exam Domains 2026: Complete Guide to All 2 Content Areas.

How Items Earn Credit on a 350-Question Exam

The PAM is built around image-intensive patient cases. NBEO's materials indicate that these cases generally carry three to six associated items, with three to ten response options per item. Both single-answer and multiple-response formats are used.

This matters for score management. A candidate who half-knows a multiple-response topic gains nothing from a partial selection, so these items reward precise, complete knowledge: the full differential, the complete set of appropriate management steps, the entire list of contraindications. When you review practice material, do not just note whether you were "mostly right." Ask whether you would have matched the complete set.

Test-day mechanics that touch your score

• Two 175-question sessions. The exam is 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. Those additions are not question-timer minutes.
• No revisiting Session 1. Once you leave for the inter-session break, you cannot go back. Finish your review of flagged items before ending the first session.
• Unscheduled breaks keep the clock running. Stepping away mid-session does not pause the timer.
• Tools on screen. An on-screen basic calculator, a searchable generic/trade drug equivalence list, an abbreviation list and a supplied scratch booklet are available. The drug list is not an exhaustive syllabus, so do not treat it as a substitute for learning pharmacology.
• Closed book. No outside materials are permitted.

Where Your Points Come From: Content Weights

The scaled score is built from performance across the whole exam, so the practical question is where the weight sits. The NBEO Part II PAM Content Outline defines two top-level condition and content areas:

NBEO also publishes a separate content matrix that cross-classifies the same material by task type. These are intersecting dimensions, not four extra additive domains, and the ranges are preserved here exactly as published:

Clinical Presentation (history, signs and symptoms) is assessed within the cases and has no separate percentage. The headline insight is that Treatment / Management is the heaviest task dimension, so a candidate who can diagnose but hesitates on management will leave score on the table. The full breakdown, including how to study each, lives in our domains guide, and a condensed review sheet is available in PAM Cheat Sheet 2026: One-Page Review of Must-Know Facts.

Pass-Rate Context Without Over-Reading It

Candidates naturally want to connect the passing score to how many people clear it. The available figures come from different populations and periods, and they should not be pooled.

• All first-time candidates, 2025-2026. 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 rather than an issuer-hosted national dataset, and their first-time population includes candidates regardless of graduation status.
• U.S. graduate cohort, October 1, 2024-September 30, 2025. The NBEO-authored Institutional Yearly Performance Report reports an 87.96% Part II first-time pass rate for a cohort of 1,628 qualifying U.S. graduates. That cohort includes only graduates in the stated interval who attempted all three NBEO parts at least once.

These two numbers measure different groups over different windows, so do not read the gap between them as a trend. Older university national rows also disagree, and no combined historical trend is inferred here. The honest summary is that most first-time candidates in the reported populations passed, but a meaningful minority did not, and the exam is not a formality.

Attempts, Retakes and Score Validity

NBEO's policies shape what a passing or failing result means for your plans.

• Six-attempt limit. After six attempts, special approval or remediation is required.
• No superscoring. NBEO prohibits superscoring, so you cannot combine the best portions of separate attempts into one result.
• No recalled items. NBEO prohibits the distribution of recalled exam items. Rely on legitimate preparation resources instead.
• Scores do not expire. NBEO says scores do not expire. PAM is a licensure examination result, not a separately renewable specialty certification, and individual licensing boards can impose additional conditions on accepting results.

Money also factors into whether to rush an attempt. The PAM fee is USD $1,490 for administrations beginning August 2026, and late registration adds $400. You register and pay through NBEO, then schedule your appointment with Pearson VUE at a center in the USA, Puerto Rico or Canada. Bring two current signed physical IDs, at least one a government photo ID, matching your registration.

Building a Preparation Plan Around the Score

Because the line is a scaled boundary you cannot reverse-engineer, the goal is comfortable clearance, not minimum survival. Tie your calendar to the exam's weights: give the 60-70% Normal Health / Disease / Trauma area the bulk of your hours, and use the 30-40% Refractive / Sensory Processes / Oculomotor Processes area for steady maintenance and calculation fluency.

For a fuller sequence, the planning detail in PAM Study Guide 2026: How to Pass on Your First Attempt goes deeper. NBEO's optional Part II PAM/TMOD Practice Databank, administered by independent third party Test Run, contains NBEO-owned questions and costs $199 for one month with a $149 additional-month renewal, subject to registration and administration-date conditions. That is a preparation charge separate from the exam fee, and neither purchasing nor completing it guarantees a pass. You can also build volume with our PAM practice tests to rehearse the format, timing and multiple-response discipline, and you can start a session on the main practice site at any point in your preparation.
