What Is on the ANCC PMHNP-BC Exam? The Five Domains and What Each One Tests

ANCC's PMHNP-BC exam has 175 questions, 150 of them scored, split across five content domains. Here is what each domain covers, how many questions it carries, what the secondary classifications add, and how to turn the counts into a study plan for a 2027 test date.

Short answer

ANCC's PMHNP-BC exam has 175 multiple-choice questions in 3.5 hours: 150 scored and 25 unscored pretest questions you cannot tell apart. Under the current test content outline, the scored questions fall into five domains: Scientific Foundation 33, Advanced Practice Skills 41, Diagnosis and Treatment 33, Psychotherapy and Related Theories 17, and Ethics, Legal Principles, and Cultural Care 26. Questions are also written with body systems, drug agents and eight age groups from infant to frail elderly in mind. As of October 29, 2026, ANCC had announced no newer outline for 2027 test dates.

The ANCC PMHNP-BC exam in one paragraph

The PMHNP-BC exam from the American Nurses Credentialing Center (ANCC) has 175 multiple-choice questions and a 3.5-hour time limit at a Prometric test center. Of the 175 questions, 150 are scored and 25 are pretest questions that do not count toward your score. ANCC says the pretest items cannot be told apart from scored ones, so every question deserves a real answer. All 150 scored questions come from one document, the PMHNP-BC Test Content Outline, effective April 28, 2023, which ANCC still lists on its PMHNP certification page as of October 29, 2026. The rest of this guide explains what that outline asks of you.

The five PMHNP-BC content domains and their question counts

ANCC's test content outline prints a fixed number of scored questions for each domain. The last column is Passy's plain-language summary of the outline's topics, not ANCC's wording.

DomainScored questionsShareWhat it covers, in short
Scientific Foundation3322%Pathophysiology, general pharmacology and psychopharmacology, neurodevelopment, neuroanatomy, neurophysiology, psychopharmacogenomics, and advanced physical assessment
Advanced Practice Skills4127%Interviewing, the mental status exam, mental health and substance use screening tools, risk assessment, psychiatric emergencies, psychoeducation, health promotion, and recovery
Diagnosis and Treatment3322%DSM-5-TR criteria and differential diagnosis, lab and diagnostic tests, evidence-based treatment choice, and prescribing and monitoring medicines
Psychotherapy and Related Theories1711%Psychotherapy principles, change theories, developmental and family theories, and building and managing the therapeutic alliance
Ethics, Legal Principles, and Cultural Care2617%Informed consent, confidentiality and its limits, ethical decision making, cultural care, equity, and patient advocacy

The printed percentages add up to 99%, and ANCC notes that the total misses 100 because of rounding. Advanced Practice Skills is the largest domain, but no single domain dominates: the three biggest together hold 107 of the 150 scored questions.

What each PMHNP-BC domain asks you to decide

Scientific Foundation questions test whether you know why a drug or a disorder behaves the way it does. Expect mechanisms, adverse effects, interactions and serious reactions. The outline names extrapyramidal symptoms and neuroleptic malignant syndrome as examples, and it lists gene-drug interactions under psychopharmacogenomics.

Advanced Practice Skills questions put you in the interview room. You choose a screening tool and read its result, judge risk, handle a psychiatric emergency or decide how to teach a patient. The outline's examples include the PHQ-9, GAD-7 and Vanderbilt ADHD scales and substance use tools such as the AUDIT, DAST, CIWA and COWS, so knowing what each instrument measures, and for whom, pays off here.

Diagnosis and Treatment questions ask what the patient has and what to do next. DSM-5-TR criteria, including duration rules, separate close diagnoses. The treatment side covers both psychiatric and general medications, with selection and monitoring, plus when to choose psychotherapy or a complementary treatment.

Psychotherapy and Related Theories is the smallest domain at 17 questions. It covers therapy models such as cognitive behavioral and interpersonal approaches, change theories such as the Transtheoretical Model, developmental and family theories, and the skills of a working alliance, including boundaries and a trauma-informed approach.

Ethics, Legal Principles, and Cultural Care carries 26 questions, more than psychotherapy. It spans consent and patient rights, confidentiality and duty to warn, involuntary treatment and decision-making capacity, cultural and spiritual care, and advocacy topics such as school and disability accommodations and family leave. ANCC also lists the ANA's Psychiatric-Mental Health Nursing: Scope and Standards of Practice here.

Because the planned bank is built on these same five domains, you can see how PMHNP-BC prep planned for launch spreads 1,700 questions across them before you decide how to study.

The secondary layer: body systems, drug agents and age groups

The outline adds a second layer that has no question counts. ANCC says the exam is developed with three secondary classifications in mind, in line with the APRN Consensus Model:

  • 13 body systems, from cardiovascular to respiratory, psychiatric among them
  • 12 drug agent groups, such as analgesic, cardiovascular, endocrine and psychiatric agents
  • 8 age groups: infant, preschool, school-age, adolescent, young adult (including late adolescents and emancipated minors), adult, older adult and frail elderly

Two practical points follow. First, the exam is across the lifespan, so a child with ADHD and a frail older adult with delirium are both fair game. Second, non-psychiatric drugs and body systems matter: a lithium patient who starts a diuretic, or an older adult whose sodium drops on an antidepressant, is a psychiatric question with a medical core.

Turning the PMHNP-BC question counts into study hours

One simple method is to give each domain study time in proportion to its scored questions, then shift hours toward your weak spots. Here is the arithmetic for a sample budget of 120 study hours, worked out by Passy:

DomainScored questionsShare of 150Hours out of 120
Scientific Foundation3322.0%26.4
Advanced Practice Skills4127.3%32.8
Diagnosis and Treatment3322.0%26.4
Psychotherapy and Related Theories1711.3%13.6
Ethics, Legal Principles, and Cultural Care2617.3%20.8

Treat this as a starting split, not a rule. If pharmacology is your weak area, move a few hours from your strongest domain into Scientific Foundation and Diagnosis and Treatment, which share most of the drug content. The free PMHNP-BC study planner builds a dated outline from your exam date, your daily minutes and one weak domain.

Pacing is easier to rehearse than to guess. ANCC allows 3.5 hours for 175 questions, which works out to 72 seconds a question in Passy's arithmetic. The handbook says there is no penalty for guessing and that you can mark questions to return to them. A timed 175-question mock exam is part of the planned PMHNP-BC prep, and checkout is not open yet.

What ANCC gives PMHNP-BC candidates to study from

ANCC's PMHNP certification page lists study aids next to the outline. Three are free and useful from the first week:

  1. The reference list. Its 16 titles, effective April 28, 2023 and updated September 3, 2025, include the DSM-5-TR, Stahl's psychopharmacology texts, a psychiatric interview text, ANA's ethics guide and the psychiatric-mental health scope and standards. ANCC says the list is not all-inclusive.
  2. Sample questions. The ANCC Certification Handbook describes them as similar to exam questions but not covering the full range of content or difficulty, with no time limit.
  3. The handbook's study advice. It suggests building a study plan about six months before your exam.

The reference list is long, so use the outline to decide what to read in each book. Recall-heavy material, such as drug classes and their monitoring, DSM-5-TR duration rules and screening tool cutoffs, also suits the flashcards planned for full PMHNP-BC prep.

How the PMHNP-BC domains show up on your score report

ANCC reports results as pass or fail. Scores are on a scale with a maximum of 500, and a passing scaled score is 350 or higher. If you fail, the report shows your scaled score and rates each content area High, Medium or Low, according to the handbook. On the PMHNP-BC outline, the major content areas are the five domains above, which is why it helps to track your practice misses by domain from the start.

A retake is possible after 60 calendar days from your last test, with no more than three tests in any 12-month period, as ANCC's retest policy stated on October 29, 2026. ANCC's 2025 certification data show that 8,840 of 10,743 first-time PMHNP testers passed in 2025, an 82% pass rate. That figure describes last year's group, not your own chances.

Which PMHNP exam this outline covers, and what to check for 2027

This outline is for ANCC's PMHNP-BC exam only. The Nurse Practitioners Certification Board (NPCB, the name under which the AANPCB does business) runs a separate PMHNP certification exam, and its certification page says its exams have 150 questions. The two boards set their own content and rules, so make sure a review book or question bank names the ANCC exam before you buy it.

For a 2027 test date, plan on the outline effective April 28, 2023 unless ANCC posts a new one. ANCC's handbook says its certification exams are updated approximately every three to five years, so check the PMHNP page again when you apply and once more before test day. If a new outline appears, its effective date tells you which version your appointment falls under. PMHNP-BC prep planned for launch is built on ANCC's five domains, not on NPCB's exam.

A first step for PMHNP-BC preparation

Start by finding out which domains already feel solid. The 20 free PMHNP-BC practice questions are split across the five domains in proportion to their question counts, with an explanation for every option, so your misses point to where your first study hours should go. Then put those hours on a calendar with the study planner.
