Validation of the ExaminationSince the inauguration of the EPPP in 1964, every effort has been made to ensure its validity. The meticulous test development process constitutes one major facet of the validation effort devoted to the assurance of content validity. Additionally, ASPPB has conducted five sets of investigations that form the basis of the content validity of the examination. The most recent study, a 24-month long Analysis of Professional Practice with a Focus on the Validation and Assessment of Competencies, was completed in 2010 and adopted by the Board of Directors of ASPPB in January 2011.
The practice analysis resulted in revised test specifications* for the Examination for Professional Psychology (EPPP) updating the knowledge base and integrating additional relevant competencies.
* The new test specifications, that is, the categories (domains) and the subcategories(knowledge statements) that comprise the test, are found in the Appendix II of the full Practice Analysis report, as well as in Appendix A of the Information for Candidates brochure.
