The EPPP: What to Know

Last reviewed August 2026

The exam, in one paragraph

The Examination for Professional Practice in Psychology (EPPP) is the standardized licensing exam used across the U.S. and Canada. It's a computer-based, multiple-choice exam administered at Pearson VUE testing centers: 225 questions in 4 hours 15 minutes, of which 175 are scored and 50 are unscored pilot items (you won't know which are which). Scores are reported on a scaled 200–800 range. ASPPB recommends 500 as the passing score for independent practice, and every licensing authority currently accepts it; a lower standard of 450 exists for supervised practice in some jurisdictions, and that one does vary. Because forms are statistically equated, there is no fixed "percent correct" that guarantees a pass — which is exactly why readiness is about consistency, not a single lucky practice score (our free diagnostic is built to show you where you stand).

How scoring actually works

This part is worth understanding properly, because the most common belief about it is wrong. Per ASPPB's own Candidate Handbook, scaled scores are "an arithmetic conversion of raw scores (the number of questions a Candidate answers correctly)" onto the 200–800 scale. That single sentence settles a lot: a hard question and an easy question are each worth exactly one correct answer on your form. Difficulty does not earn you extra credit, and there is no partial credit.

What difficulty does affect is the conversion itself, and it operates on the whole exam form rather than on individual items. This is called equating. In ASPPB's words: if a form is easier than the form the passing score was set on, more questions have to be answered correctly to reach 500; if a form is harder, fewer do. The stated purpose is that candidates are "not rewarded because their exam was easier nor penalized because it was more difficult." So the honest answer to "how many do I need to get right?" is that it moves with the form you sit. A figure of roughly 70% of the 175 scored items gets quoted often, and it is a reasonable average, but it is an average and not a line painted on the floor.

The 50 unscored pilot items are not a trap. They are effectively a random subset, you cannot identify them, and they cannot be studied for. The practical consequences are just two: answer every question, and don't let a strange-feeling stretch of items convince you the exam is going badly, because some of what you're reading may not count.

Why we set our readiness bar above 70%

Here is the part almost nobody tells you, and it is the reason we don't call 70% "ready." Even holding the cut fixed at the commonly cited 123 of 175, a 175-item test carries real sampling noise. Treating items as independent, a candidate whose true ability sits exactly at the cut has close to a coin flip on any given day. Ability a few points higher is what turns a coin flip into a comfortable margin:

Two honest caveats. That table holds the raw cut fixed, so real equating variation widens the uncertainty rather than narrowing it. And it describes ability on the real exam, not a score on anyone's practice material, ours included. No practice score predicts a result, and we don't publish a pass rate we can't prove.

What it does explain is a design decision you can hold us to: our readiness bands sit above the nominal cut on purpose, and they read from full-length timed exams on material you haven't seen before, because scores on questions you've already answered measure memory rather than readiness. We'd rather tell you to wait a week than send you to a coin flip.

The path to test day

Licensure starts with your state or provincial board, not with the exam. In broad strokes: you apply to your board → the board determines your eligibility → you're authorized to register for the EPPP through ASPPB → you schedule at a Pearson VUE center. Timelines vary widely by jurisdiction — some boards approve in weeks, others take months — so start the paperwork earlier than feels necessary. Exam fees are set by ASPPB plus a test-center administration fee (budget roughly $700 all-in as of this writing; check current fees when you register).

What's on it

Eight content domains, weighted (current domain structure — verify current weights on ASPPB's site): biological bases of behavior; cognitive-affective bases; social and cultural bases; growth and lifespan development; assessment and diagnosis; treatment, intervention, prevention and supervision; research methods and statistics; and ethical, legal, and professional issues. Our question bank, lessons, and diagnostic report map to these domains one-to-one, so your strengths and weaknesses translate directly to the real blueprint.

Retakes and score reporting

If you don't pass, your board's own rules on waiting periods and additional requirements govern, so verify before scheduling. Two things hold regardless of jurisdiction: nobody may sit either part of the EPPP more than four times in any 12-month period, and ASPPB recommends waiting roughly 90 days from your last test date to allow real preparation time. Worth knowing in advance: candidates who don't reach the passing standard automatically receive domain-level performance feedback as a bar graph at the test center, at no cost — and it cannot be regenerated, so keep it. It is the most useful document you'll get for planning a retake. One implication worth internalizing early: the cost of walking in unready is measured in months, not dollars. That's why our whole product is oriented around knowing you're ready before you book — starting with the free diagnostic.

The exam is changing (Fall 2027)

ASPPB is moving to an integrated exam that combines knowledge and skills assessment — a single examination with new item formats, including audio/video scenario items. If you're testing before mid-2027, prepare for the current EPPP and largely ignore the noise. If you're further out, see our 2027 Exam Changes page for what's known and how our platform is already built for scenario- and media-based practice.

This page is educational and general. Your licensing board's current requirements are the authority — always verify eligibility, fees, retake rules, and passing standards with your board and ASPPB directly.
