ExploreAbout this exam
Part II PAM/TMOD (Patient Assessment and Management / Treatment and Management of Ocular Disease) is one of the professional examinations administered by the National Board of Examiners in Optometry (NBEO), an independent national board that assesses the knowledge, skills, and clinical competencies required for independent practice of optometry. According to NBEO's own description, Part II PAM evaluates clinical decision-making and diagnostic reasoning through patient-based scenarios; it measures a candidate's ability to interpret findings, develop management plans, and provide evidence-based patient care. It sits within NBEO's core competency sequence alongside Part I ABS (applied basic science) and Part III PEPS (a simulated-live patient encounter), and together these exams give state licensing boards a measure of professional readiness. This page is an independent study resource for candidates preparing for Part II; it is not affiliated with, endorsed by, or sponsored by NBEO, and it does not reproduce NBEO exam content. Because the exam is built around patient-based scenarios rather than isolated facts, preparation should center on structured case reasoning: extracting the pertinent findings from a presentation, ranking differential diagnoses, selecting and justifying diagnostic tests, and committing to an evidence-based management plan with appropriate follow-up and referral thresholds. Pair case-based practice with review of the conditions and therapeutic decisions you are least confident about, and use NBEO's published policies, fees, scoring, and calendar pages for all administrative details.
What you'll study
About NBEO TMOD preparation
What does Part II PAM/TMOD actually test?
NBEO describes Part II PAM as an evaluation of clinical decision-making and diagnostic reasoning delivered through patient-based scenarios. In practice that means interpreting findings, building a differential, choosing management plans, and delivering evidence-based care. Prepare by rehearsing full cases end to end, not by memorizing isolated lists of signs.
How is Part II related to Part I and Part III?
NBEO presents Part I ABS, Part II PAM/TMOD, and Part III PEPS as its core competency testing sequence. Part I covers scientific foundations such as anatomy, physiology, pathology, pharmacology, and optics applied to clinical problem-solving; Part III addresses case analysis and essential skills in a simulated-live patient encounter. Part II is the clinical-reasoning bridge between them.
What is the exam format, length, and fee?
NBEO publishes format, fees, scoring, and reporting details on its own Exam Information, Exam Fees, and Scoring and Reporting pages. Those specifics are not reproduced here because they are set and revised by NBEO. Check the current official pages before you register, and treat any third-party figure as unverified until you confirm it at the source.
How hard is Part II, and what trips candidates up?
The common failure mode is not missing facts but weak commitment: candidates list several plausible diagnoses without choosing one, or describe tests without linking them to a management decision. Scenarios reward prioritizing the most likely diagnosis, justifying the next step, and stating a concrete plan with follow-up. Practice converting every case into a single defensible decision.
In what order should I study for the NBEO sequence?
Follow the sequence NBEO describes: Part I establishes the basic-science foundation, Part II builds clinical decision-making on it, and Part III tests case analysis and performance skills. Study Part II by integrating basic-science mechanisms into case reasoning rather than re-learning them in isolation, so the same material serves both exams.
Can I retake Part II, and how do I register?
Registration, eligibility, and retake rules are governed by NBEO's Exam Policies and Eligibility and its exam calendar, and candidates agree to those policies when registering. This page does not restate them because they change. Review the official policies thoroughly before registering and confirm deadlines on the NBEO calendar.
When are scores released?
NBEO handles scoring, equating, scaling, and score release, and posts results to your NBEO account. Release timing varies by exam and administration, so consult NBEO's Scoring and Reporting page rather than relying on a date from a prior cycle. For example, NBEO announced that August 2026 Part III, ISE, and LSPE scores were released on October 9, 2026.
Where do I find official NBEO dates and announcements?
Use the NBEO site directly: the Exam Information pages for each exam, Exam Fees, Scoring and Reporting, Test Accommodations, and the Exam Calendar. NBEO also posts news items on its home page, such as registration openings and score releases. Verify anything time-sensitive there before making travel or study plans.
