1.1 Two-Part 2026 EPPP and the Candidate Handbook
Key Takeaways
- The current Examination for Professional Practice in Psychology (EPPP) is a two-part exam: EPPP Part 1-Knowledge and EPPP Part 2-Skills.
- Part 1 has 225 items (175 scored, 50 unscored pretest); Part 2 has 170 items (130 scored, 40 unscored pretest).
- Part 1 measures foundational psychology knowledge across eight content domains; Part 2 measures applied decision-making across six competency clusters.
- Anchor all logistics to the current ASPPB EPPP Candidate Handbook, then confirm jurisdiction-specific rules with your licensing authority.
Name the exam correctly first
The first orientation task is precision: in 2026 the Examination for Professional Practice in Psychology (EPPP) is a two-part exam administered by the Association of State and Provincial Psychology Boards (ASPPB) through Pearson VUE. EPPP Part 1-Knowledge assesses general psychology knowledge, intervention, assessment, and foundational graduate-training content. EPPP Part 2-Skills assesses application of that knowledge to decision-making in real-world independent-practice situations.
This distinction is not cosmetic. Part 1 asks whether you can recognize and apply core knowledge; Part 2 asks whether you can choose the defensible next professional action when facts are incomplete. A candidate who studies only definitions will be under-prepared for the scenario reasoning that dominates Part 2.
The eight Part 1 content domains
Part 1 is built on eight weighted content domains. Knowing the approximate weights tells you where to invest study time. The two largest domains tie at 16% each: Assessment and Diagnosis and the Ethical/Legal/Professional domain, followed closely by Treatment, Intervention, Prevention, and Supervision at 15%.
| Part 1 content domain | Weight | High-yield focus |
|---|---|---|
| Biological Bases of Behavior | 10% | Neuroanatomy, neurotransmitters, psychopharmacology |
| Cognitive-Affective Bases | 13% | Learning theory, memory, emotion, motivation |
| Social and Cultural Bases | 11% | Attribution, attitudes, group process, diversity |
| Growth and Lifespan Development | 12% | Stage theories, attachment, aging |
| Assessment and Diagnosis | 16% | Psychometrics, DSM-5-TR, test selection |
| Treatment, Intervention, Prevention, Supervision | 15% | Evidence-based therapies, outcome research |
| Research Methods and Statistics | 7% | Design validity, inferential statistics |
| Ethical, Legal, Professional Issues | 16% | APA Ethics Code, confidentiality, duty to warn |
The Part 2 competency clusters
Part 2-Skills is organized around six practice competency clusters rather than knowledge domains: (1) Scientific Orientation to Practice, (2) Assessment and Intervention, (3) Relational Competence, (4) Professionalism, (5) Ethical Practice, and (6) Collaboration, Consultation, and Supervision. Each Part 2 item presents a clinical or professional scenario and asks for the most appropriate action.
| Current EPPP part | Total items | Scored / pretest | Primary emphasis |
|---|---|---|---|
| Part 1-Knowledge | 225 | 175 scored / 50 pretest | Foundational psychology knowledge |
| Part 2-Skills | 170 | 130 scored / 40 pretest | Applied independent-practice judgment |
Why the two-part frame changes study planning
Build two notebooks. The knowledge notebook holds domains, theories, disorders, assessments, interventions, research designs, statistics, and the APA Ethics Code. The decision notebook holds case facts, risk cues, documentation choices, consultation triggers, referral thresholds, supervision duties, and cultural adaptations. The same topic appears in both from different angles.
A depression scenario shows the split. Part 1 might ask about diagnostic features, differential diagnosis, the evidence base for cognitive-behavioral therapy, or the validity of a depression inventory. Part 2 might ask what you should do next when the client adds suicide risk, voices cultural mistrust, raises a medication concern, or when a supervisee mishandles the case.
The Candidate Handbook is the controlling source
Use the current ASPPB EPPP Candidate Handbook as your fact anchor for items, time, fees, identification, scoring, and retakes; it is updated periodically, so always download the latest edition rather than relying on a screenshot. Then confirm jurisdiction rules with your board or provincial college. ASPPB provides the examination program and recommended passing scores, but your licensing authority decides eligibility, whether and when it uses each part, supervised-practice rules, jurisprudence exams, remediation, and final licensure.
Keep those two sources distinctly separated in your notes so you never mistake a recommendation for a legal requirement.
Common orientation traps
Three misconceptions cost candidates time at the very start. Trap one: treating "the EPPP" as a single test. Many older resources, forum threads, and prep books predate the two-part rollout and describe only a knowledge exam; if your jurisdiction requires Part 2, those materials leave a blind spot in applied reasoning. Trap two: assuming Part 2 is just "more content." Part 2 is a situational-judgment instrument — every item asks for the most appropriate action, and the credited answer is the most professionally defensible response, not the most knowledgeable-sounding one.
Trap three: assuming the eight Part 1 domains are equally weighted, then over-studying a comfortable area such as biological bases while under-studying ethics or treatment, which carry the heaviest weights.
A simple orientation checklist
Before any deep content study, settle these orientation facts in writing: (1) which part(s) your jurisdiction requires and in what order; (2) the current item counts and time limits from the latest handbook; (3) the eight Part 1 domains with their approximate weights; (4) the six Part 2 competency clusters; and (5) the source date of every logistics fact you record. Re-download the Candidate Handbook each time you reach a new milestone, because ASPPB revises it periodically and a stale screenshot is one of the easiest avoidable errors in the entire process.
Orientation done well turns the rest of your preparation into focused content work rather than anxious fact-checking. A final orientation habit: write each logistics fact in your notes with the phrase "per the current Candidate Handbook, retrieved [date]" so that when you revisit the note months later you can instantly tell whether it needs re-verification against a newer edition.
