How this list was compiled: Our own questions, written to the domains and weights of the EPPP (Part 1-Knowledge) on ASPPB's page Current Examination for Professional Practice in Psychology (EPPP) Content Areas (https://asppb.net/exams/asppb-examination-for-professional-psychology-eppp/eppp-exam-topics/, read 2026-10-12), which match Appendix A of the EPPP Candidate Handbook, September 2026 (https://asppb.net/wp-content/uploads/EPPP-Candidate-Handbook-Sep-2026.pdf, read 2026-10-12). The eight domains and their weights: biological bases of behavior 10%, cognitive-affective bases of behavior 13%, social and cultural bases of behavior 11%, growth and lifespan development 12%, assessment and diagnosis 16%, treatment, intervention, prevention and supervision 15%, research methods and statistics 7%, ethical, legal and professional issues 16%. The bank holds 8, 10, 9, 10, 13, 12, 6 and 13 questions in that order. Every fact was read on 2026-10-12 in the public text the question names: the National Institute of Mental Health, MedlinePlus, the National Institute on Deafness and Other Communication Disorders, Wikipedia, the APA Ethical Principles of Psychologists and Code of Conduct (a copy of apa.org/ethics/code archived June 2, 2025, cited by standard number) and the Canadian Code of Ethics for Psychologists, Fourth Edition.

How it works
These EPPP practice tests draw on 81 questions of our own for Part 1-Knowledge. They are unofficial: this site is not affiliated with, endorsed by or sponsored by the Association of State and Provincial Psychology Boards (ASPPB).
Read the full guide
Eight domains, in the exam's shares
The bank follows the weights on ASPPB's content areas page, read October 12, 2026. Its 81 questions split 8, 10, 9, 10, 13, 12, 6 and 13 across the eight domains, from biological bases to ethics and law.
The exam's pace on the clock
Exam mode asks 60 questions in 68 minutes, the pace of the real 225 questions in 4 hours 15 minutes.
Where the answers come from
Ethics answers cite the APA Ethics Code by standard number, and the Canadian code. Clinical answers cite NIMH, NIDCD and MedlinePlus. Theory, psychometrics and statistics answers cite Wikipedia. No review book and no paid practice exam was used.
Questions and answers
Are these EPPP online practice tests free?
Yes. They are free EPPP practice tests, with no account to open. Every question shows the right answer, a short reason and a link to the public page where the fact can be checked.
How many questions are on the EPPP?
Part 1-Knowledge has 225 multiple-choice questions, each with three or four choices. Only 175 are scored; the other 50 are pretest questions. By ASPPB's candidate handbook of September 2026, candidates get 4 hours 15 minutes for them.
What is a passing score on the EPPP?
Scores are reported on a scale of 200 to 800. ASPPB recommends 500 for independent practice, 450 for supervised practice, and each licensing board sets its own standard. The number of right answers needed changes with each form.
Is this the official EPPP practice test?
No. ASPPB sells its own sample exams, online and at Pearson VUE centers, to candidates a licensing authority has approved. This bank is separate and unofficial: every question is our own, written from the public source it names.
Do I have to take EPPP Part 2?
It depends on where you apply. By ASPPB, all 66 member jurisdictions require Part 1-Knowledge and some also require Part 2-Skills, which is taken only after Part 1 is passed. Ask your licensing board. This page covers Part 1 only.
