Examination for Professional Practice in Psychology (Part 1–Knowledge)

EPPP® Practice Exam

This EPPP practice exam covers the eight content domains of the EPPP (Part 1–Knowledge) in the proportions ASPPB publishes. The exam itself is 225 multiple-choice questions, of which 175 are scored, in 4 hours 15 minutes. A free 25-question diagnostic shows which domains need the most work before you commit to a study plan.

The free EPPP diagnostic is being prepared and is not open yet. The exam facts and the content outline on this page are current.

The EPPP is broad rather than deep in any one place. Its two largest domains, Assessment and Diagnosis and Ethical, Legal, and Professional Issues, are 16% each, and the smallest, Research Methods and Statistics, is 7%. With content that broad, the efficient approach is to measure first and study second.

Every question here is tagged to one of the eight domains and comes with a written reason for each option. On an exam where a single sitting costs several hundred dollars, knowing why you missed a question is worth more than the question itself.

Who takes it

The EPPP is the licensing examination ASPPB provides to its member psychology boards in the United States and Canada. You do not register with ASPPB directly: you must first be approved by the licensing authority in the jurisdiction where you are seeking licensure, and each authority sets its own requirements. Most candidates hold a doctoral degree in psychology and have completed supervised doctoral and postdoctoral experience.

How to use the bank for the EPPP exam

  1. 1

    Start with the diagnostic and rank the eight domains

    25 questions, scored by domain. Order the domains from weakest to strongest and let that order, adjusted for weight, set your schedule.

  2. 2

    Put the heavy domains first

    Assessment and Diagnosis (16%), Ethical, Legal, and Professional Issues (16%) and Treatment, Intervention, and Prevention and Supervision (15%) are 47% of the exam between them. A weak result in any of the three should move it to the top of the list.

  3. 3

    Practice the length, not just the content

    225 questions in 4 hours 15 minutes is a little over a minute each, with no scheduled breaks: the clock keeps running if you take one. Timed sets and full-length mocks build the pace that makes a break affordable.

  4. 4

    Review by reason, not by score

    For each miss, read why the keyed answer is right and why the option you chose is wrong. Two questions missed for the same reason are one gap, and closing it is worth more than doing fifty new questions.

What is in the paid EPPP bank

  • The question bank

    The EPPP bank is still being written. The live count appears here when questions are published.

  • Every option explained

    A written reason for every option, right and wrong, plus a one-line takeaway, a cited reference and the outline task the question tests.

  • Tutor mode and timed mode

    Tutor mode shows the explanation after each question. Timed mode holds everything back until the end, at exam pace.

  • A readiness band, by domain

    Your first-attempt results weighted the way the exam weights its domains, shown as a band rather than a pass probability: nobody outside the exam owner knows the cut score.

  • A study plan

    Set your exam date and the plan divides the questions you have not seen across the days you have left, weakest domains first, with the mock exams placed in the back half.

How the questions are written and checked

  1. Step 1

    Written to the public outline

    Each question is written by AI against one task in ASPPB's published content outline. Nothing is taken from the exam itself.

  2. Step 2

    Solved blind by a second model

    A different model answers the question without seeing the key. If it does not reach the same answer, the question is not published.

  3. Step 3

    Audited for flaws and duplicates

    A separate pass looks for item-writing flaws: two defensible answers, a giveaway in the wording, a rationale that contradicts the key. Near-duplicates are removed.

  4. Step 4

    Corrected in public

    Learners can report any question. Reports and answer statistics flag questions for withdrawal or correction, and every correction is logged.

There is no human subject-matter-expert review in that process, and we do not claim one. What you get instead is a cited reference on every question, so you can check it yourself. Read the full methodology or see the corrections log.

EPPP practice questions: common questions

How many questions are on the EPPP?

225 multiple-choice questions. 175 are scored and 50 are unscored pretest questions that are not identified. ASPPB's handbook says each question has three or four possible responses.

How long is the EPPP exam?

4 hours 15 minutes for the questions. The appointment is a little longer, because it also includes a short acknowledgement statement, a tutorial and an exit survey. There are no scheduled breaks, and the clock does not stop if you take one.

What is a passing score on the EPPP?

Scores are reported on a scale of 200 to 800. ASPPB recommends a passing score of 500 for independent practice and 450 for supervised practice, but each licensing authority decides the score it requires, so check with yours.

How much does the EPPP cost?

Each sitting costs a $600 ASPPB exam fee plus a $91.88 test center sitting fee, before any tax. Both are non-refundable, and the fees your licensing authority charges for the application are separate.

Is this practice exam free?

The 25-question diagnostic is free and needs no account. The full bank, timed mode and full-length mock exams are part of a paid pass, which is charged once and does not renew.

Are these sample questions from the EPPP itself?

No. They are original questions written to ASPPB's published content areas. The exam's own questions are confidential and are not available to any practice provider.

Is the EPPP changing?

ASPPB has published new content specifications that become operational in fall 2027. Exams before that point use the current eight-domain specifications, which are the ones this bank follows.

How many times can I retake the EPPP?

Retakes need the approval of your licensing authority, which sets its own waiting periods and attempt limits. ASPPB itself allows no more than four attempts in any 12-month period and recommends waiting about 90 days between attempts. The full fees are due for every sitting.
