EPPP Study Plan: How Long to Study and 8-, 12- and 16-Week Schedules by Content Area
ASPPB doesn't set a study length for the EPPP. Size yours from your weekly hours and testing window, weight it by the eight Part 1 content areas, and follow an 8-, 12- or 16-week schedule that ends in full-length timed practice.
Short answer
ASPPB doesn't publish a recommended study length, so size it from your weekly hours, how recently you finished coursework, and your board's testing window. As a practical range, not an ASPPB rule: about 8 weeks at 20 to 25 hours a week, 12 weeks at 12 to 15 hours, or 16 weeks at 8 to 10 hours around a full-time job. Weight the hours by ASPPB's eight content areas, give extra time to areas where you and national averages run low, and finish with full 225-question timed rehearsals.
How long to study for the EPPP
ASPPB doesn't recommend a number of weeks or hours. What it does say, on its Which Exam Should I Take? page, is that it's best to take Part 1 as soon as possible after academic training, while the knowledge is fresh. Your study length depends on four things:
- Weekly hours you can protect. This drives the calendar more than anything else.
- Distance from coursework. Recent graduates often need review; candidates years out often need to relearn.
- Your baseline. A mixed diagnostic across all eight areas shows how much ground you have to cover.
- Your testing window. After you pay in Clarus, you have 12 months to sit, or less if your board's window ends sooner. ASPPB's handbook also warns that EPPP slots at Pearson VUE are limited, so book early once you've picked a date.
Here are three schedules built from those inputs. The weekly hours are Passy's editorial ranges, not ASPPB guidance:
| Schedule | Hours a week | Fits |
|---|---|---|
| 8 weeks | 20 to 25 | Recent graduates with a strong diagnostic and room for near-full-time study |
| 12 weeks | 12 to 15 | Most candidates studying around internship, postdoc or part-time work |
| 16 weeks | 8 to 10 | Full-time jobs, family demands, or a long gap since coursework |
Weight your EPPP hours by content area
Start from ASPPB's published weights, then shift a little time toward areas where first-time candidates score lowest. The averages below are from ASPPB's 2026 doctoral program report (accredited programs, 2021–2025); the last column is a suggested starting split, which you should adjust to your own diagnostic.
| Content area | Weight | About this many scored items | Accredited-program average correct | Suggested share of content time |
|---|---|---|---|---|
| Biological bases of behavior | 10% | 18 | 72.22% | 10% |
| Cognitive-affective bases of behavior | 13% | 23 | 71.91% | 12% |
| Social and cultural bases of behavior | 11% | 19 | 69.18% | 11% |
| Growth and lifespan development | 12% | 21 | 65.86% | 14% |
| Assessment and diagnosis | 16% | 28 | 68.89% | 17% |
| Treatment, intervention, prevention and supervision | 15% | 26 | 71.33% | 14% |
| Research methods and statistics | 7% | 12 | 65.96% | 9% |
| Ethical, legal and professional issues | 16% | 28 | 77.99% | 13% |
Item counts are Passy's approximation from the weights and the 175 scored items. Don't cut ethics below its weight unless your own practice scores there are strong: it's tied for the heaviest area at 16%, and a high average score doesn't make it optional. The difficulty guide explains why assessment and diagnosis is where the most scored items are lost on average.
Within each area, work from ASPPB's knowledge statements (KN1 to KN71) as a checklist, and test yourself as you go with domain-by-domain EPPP practice planned for launch.
The 12-week EPPP schedule
This is the default. Each content week mixes new review with a set of questions from earlier weeks, so older material doesn't fade.
| Week | Focus |
|---|---|
| 1 | Diagnostic across all eight areas; list your weak spots; confirm your testing window and book a date |
| 2 | Assessment and diagnosis |
| 3 | Research methods and statistics, linked to the psychometrics from week 2 |
| 4 | Treatment, intervention, prevention and supervision |
| 5 | Ethical, legal and professional issues |
| 6 | Growth and lifespan development |
| 7 | Cognitive-affective bases of behavior |
| 8 | Biological bases of behavior |
| 9 | Social and cultural bases of behavior; first mixed review of weeks 2 to 8 |
| 10 | First full-length timed rehearsal; review every miss by area |
| 11 | Second full-length rehearsal; targeted work on the two weakest areas |
| 12 | Light mixed review and recall drills; test-day logistics; no new full-length test in the last two or three days |
A practical weekly rhythm at 12 to 15 hours: about two-thirds on content review and practice in the week's area, one-third on mixed questions and reviewing errors. For weeks 10 and 11, the session should match the real one: 225 questions in 4 hours 15 minutes with no scheduled break. You can do that with a timed 225-question rehearsal in the planned EPPP mock exam, once full prep launches.
The 8-week EPPP schedule
Two areas a week, with less room for error:
| Week | Focus |
|---|---|
| 1 | Diagnostic; assessment and diagnosis |
| 2 | Research methods and statistics; treatment, intervention, prevention and supervision |
| 3 | Ethical, legal and professional issues; growth and lifespan development |
| 4 | Cognitive-affective bases; biological bases |
| 5 | Social and cultural bases; mixed review of everything so far |
| 6 | Full-length timed rehearsal; weak areas |
| 7 | Second full-length rehearsal; weak areas |
| 8 | Light review, recall drills and logistics |
Use this only if your diagnostic is already solid. If week 6's rehearsal shows several areas well below the rest, moving the date is cheaper than a second $691.88 attempt. Rescheduling at least 32 days ahead avoids Pearson VUE's $87.50 fee under both of ASPPB's published cutoffs; the registration guide explains the discrepancy.
The 16-week EPPP schedule
The same sequence as the 12-week plan, with two weeks for each of the four areas that carry the most risk:
| Weeks | Focus |
|---|---|
| 1 | Diagnostic and plan |
| 2–3 | Assessment and diagnosis |
| 4 | Research methods and statistics |
| 5–6 | Treatment, intervention, prevention and supervision |
| 7–8 | Ethical, legal and professional issues |
| 9–10 | Growth and lifespan development |
| 11 | Cognitive-affective bases of behavior |
| 12 | Biological bases of behavior |
| 13 | Social and cultural bases of behavior |
| 14 | First full-length timed rehearsal; review by area |
| 15 | Second full-length rehearsal; weakest areas |
| 16 | Light review and logistics |
On a long plan, short daily recall keeps early areas alive; flashcards for the eight Part 1 areas, planned for full prep, are meant for that kind of ten-minute session.
Where ASPPB's sample exams fit
ASPPB offers sample exams to candidates whose board has authorized them, through their Clarus account:
- Online (SEPPPO): 100 questions, $30 per attempt, 2 hours of total time. The handbook says the clock keeps running if you pause, the exam must be finished within one week of starting, and the fee is forfeited if you don't complete it within 90 days.
- At a Pearson VUE center (SEPPP): 100 questions, $82.50 per attempt, using the real test software under test-center conditions.
- Two Part 1 forms only, so the questions repeat after a second attempt in the same mode.
- Percent correct only. ASPPB says that because the items are retired or unused, it doesn't recommend using the sample exams to find areas that need more study.
So use them for what ASPPB designed them for: getting used to the screen, the tools and the conditions. One attempt in weeks 10 or 11 of the 12-week plan is a reasonable slot. The online version's pace is a little more generous than the real exam's: 72 seconds per question (100 in 2 hours) against 68.
If your EPPP date might fall after the fall 2027 switch
ASPPB's integrated EPPP replaces Part 1 for first-time candidates once it launches in fall 2027; no exact day has been announced. Part 1 study carries over, because the integrated blueprint lists the same core areas, such as biological, cognitive-affective, social and cultural bases and lifespan development, under its Scientific Orientation to Practice domain. But the format, weights and item types change, so a first-time candidate whose date could slip past the launch should read the EPPP 2027 guide before choosing a schedule.
Build your own EPPP schedule
Enter your test date and daily study time in the free EPPP study planner: it weights your days by the eight Part 1 percentages and warns you if your date falls after the integrated EPPP's fall 2027 launch. Take the 20 free EPPP practice questions as your week-1 diagnostic, then match a 30-, 90- or 180-day access period to your schedule when full prep opens.
