Association of State and Provincial Psychology Boards

The Examination for Professional Practice of Psychology (EPPP) is a licensing examination developed by the Association of State and Provincial Psychology Boards (ASPPB) that is used in most U.S. states and Canadian provinces.

The Examination is multiple choice, and tests eight content areas all representing a specific percentage of the exam. These include the biological bases of behavior (12%), cognitive-affective bases of behavior (13%), social and multicultural bases of behavior (12%), growth and life-span development (12%), assessment and diagnosis (14%), treatment, intervention, prevention, and supervision (14%), research methods and statistics (8%), and ethical, legal and professional issues (15%).

It has been demonstrated that graduates of regionally accredited programs tend to get higher mean scores than those of regionally unaccredited programs. It has also been argued that clinical psychology programs whose graduates have higher EPPP scores tend to possess the following features: higher admissions standards, a higher faculty to graduate student ratio, and more research. In general, doctoral students score higher than master's students, PhDs outperform PsyDs and EdDs, and clinical psychology students outperform counseling and school psychology students.

However, in spite of the near universal use of the EPPP in North America, its validity has been questioned. Specifically, no evidence in favor of the EPPP's predictive, incremental, or criterion validities has yet been provided, and it appears to have only been evaluated in terms of content validity. Thus, there appears to be no empirical evidence demonstrating that the EPPP is associated with relevant professional performance criteria, is predictive of future professional performance, or incrementally adds to the process of licensure evaluation.

In a study using program-level national data (i.e., not individual data points per application but aggregated by program), EPPP scores were positively associated with: GRE scores, US News and World Report Scores, Research Emphasis of the program, % of faculty in the program who ascribe to a cognitive behavioral orientation, GPA, and % of students receiving an APA-approved internship. Negative predictors of EPPP score included: Rate of admittance, US News and World Report Rank, and % of minorities in the program.

Further, much remains unknown about the relationships between demographic variables and EPPP performance. In the only known study of demographic variables using individual data points. (cited in ), no score differences were found according to gender or disability status, but whites were found to pass at much higher rates that minority applicants.
