BNNP Exam Domains 2026: Complete Guide to All 4 Content Areas

Domain Overview: How the 200 Questions Break Down

The Behavioral Neurology & Neuropsychiatry Certification examination, administered by the United Council for Neurologic Subspecialties (UCNS), draws its 200 multiple-choice questions from a content outline organized into four domains. These domains - Structural and Functional Neuroanatomy, Neuropsychiatric Assessment, Treatments, and Neurobehavioral and Neuropsychiatric Syndromes - are reflected in the certification outline that Vanderbilt's OCCAM-BNNP curriculum reproduces for candidate reference. Understanding what each domain actually covers, and how it might appear in question form, is the single most useful thing you can do before opening a question bank.

This guide walks through each domain individually, then ties them together with format details and a study sequence. If you want a broader look at how difficult the exam is relative to your background, see How Hard Is the BNNP Exam? Complete Difficulty Guide 2026. For a condensed reference once you've studied each domain in depth, bookmark the BNNP Cheat Sheet 2026: One-Page Review of Must-Know Facts.

Domain 1: Structural and Functional Neuroanatomy

Because this domain underlies the other three, candidates coming from a general neurology background often find it more familiar than psychiatry-trained candidates, while the reverse is true for Domain 2. If your training didn't emphasize network-level functional anatomy, plan extra review time here rather than assuming clinical experience alone will cover it.

Domain 2: Neuropsychiatric Assessment

Expect questions that present a vignette with test scores or exam findings and ask you to select the next best step or the most likely interpretation - not simple recall of a test's name. This domain rewards candidates who have hands-on experience interpreting neuropsychological reports rather than just ordering them.

Domain 3: Treatments

Treatment questions on this exam are rarely "which drug treats X" in isolation - they tend to embed a comorbidity, an age-related consideration, or a competing risk that changes the correct answer. Candidates who only study first-line therapy without considering exceptions tend to lose points here.

Domain 4: Neurobehavioral and Neuropsychiatric Syndromes

Because Domain 4 draws so heavily on anatomy (Domain 1), assessment (Domain 2), and treatment knowledge (Domain 3), it's worth studying last in your sequence - after the foundational domains are solid - so that syndrome-based vignettes make full sense on first read rather than requiring you to backfill anatomy or pharmacology mid-question.

Exam Format and How Domains Show Up on Test Day

The BNNP exam consists of 200 multiple-choice questions administered over four hours of testing time, split into two parts with an optional break of up to 15 minutes between them. Once you submit Part 1, you cannot return to those answers - a detail that matters for pacing across all four domains, since you can't "save" uncertain anatomy questions to revisit after finishing syndromes later in the exam.

The exam is closed-book and delivered either at a physical testing center or online with ProctorU live remote proctoring. It's offered biennially in even-numbered years, and the 2026 administration runs November 16-20, with an application deadline of May 1 (extended deadline May 15) and approved-candidate scheduling closing November 2. For the full timeline of deadlines and scheduling windows, see BNNP Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

UCNS uses criterion-referenced standard setting rather than grading on a curve, and reports an 88% historical average initial-examination pass rate. For a deeper breakdown of what that figure means and how it's calculated, read BNNP Pass Rate 2026: What the Data Shows. If you want specifics on the score threshold itself, see BNNP Passing Score 2026: Exactly What You Need to Pass.

Mapping a Study Schedule to the Four Domains

Rather than studying generically, sequence your review around the dependency structure between domains: anatomy first, assessment and treatment next, syndromes last. This lets each later domain reinforce the foundation instead of requiring you to learn everything simultaneously.

For a more detailed week-by-week plan with resource recommendations, see the BNNP Study Guide 2026: How to Pass on Your First Attempt. You can build integrated, timed vignette practice using the question sets on our practice test platform, which mirrors the two-part, no-return format of the actual exam so pacing feels familiar on test day.

How Domain Mastery Connects to Eligibility and Practice

Domain content isn't studied in a vacuum - it reflects the day-to-day work of clinicians who pursue this credential. Eligibility runs through four routes: completing a UCNS-accredited BNNP fellowship (minimum 12 months, application within 48 months of completion), the practice track (36 months with at least 25% subspecialty practice during the preceding 60 months, plus two physician verification letters), an academic appointment at an accredited fellowship, or internationally trained faculty status at a UCNS-accredited training program. UCNS confirmed in August 2026 that the practice track remains open, which matters for clinicians without a formal fellowship. Full eligibility documentation requirements are covered in BNNP Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Because all four eligibility paths presuppose applied subspecialty experience, the exam's syndrome-heavy Domain 4 content and assessment-focused Domain 2 content tend to align closely with what practice-track and fellowship-trained candidates already do clinically - the exam is validating existing competency, not introducing entirely new material.

Registration carries its own mechanics worth planning around: the initial fee is $1,700 ($680 nonrefundable application fee plus $1,020 examination fee), with a $250 discount for eligible UCNS-accredited fellowship applicants bringing the total to $1,450. An extended application surcharge of $500 applies after the initial deadline, and reexamination costs $1,020. Full breakdowns are in BNNP Certification Cost 2026: Complete Pricing Breakdown.

Once certified, maintaining the credential involves annual C-cert requirements starting the year after initial certification: designated readings and a 25-question quiz completed in 100 minutes, requiring at least 80% within three attempts, at a fee of $175 (discounted to $150 if paid by June 1). Requirements must be finished by December 31 each year, and missing them for two consecutive years results in loss of certification - a good reason to treat your domain knowledge as something to maintain, not just pass once.
