The Psychological Services Bureau (PSB) became involved in designing entry-level examinations for health profession education programs in 1955 when nursing education professionals identified and communicated their need for these examinations. There was no fully satisfactory measurement or assessment tool then available to assist in determining if an applicant had the necessary readiness, competence and prerequisite knowledge to successfully meet the learning challenge of the program of study ahead, or the standards of performance in the health career choice.

PSB has expanded the product selections offered for entry-level examinations to provide virtually any program of education in the health occupations field assistance in predicting applicant success.

The Psychological Services Bureau endorses the principles for technical quality of psychological and educational tests as established by the standard for educational and psychological testing prepared by the American Psychological Association, American Educational Research Association, and the National Counsel on Measurement in Education. PSB fulfills a commitment to maintain a high standard within the test publishing community as a founding member of the Association of Test Publishers and membership and participation in various professional organizations.
