A project was undertaken to refine an existing self-assessment system and to develop self-paced learning modules for use in the continuing education of physician assistants (PA). Included among the major activities of the project were the following: (1) modification of the existing criterion-referenced Physician Assistant Self-Assessment Examination (PA-SAE) based on internal consistency and item analyses; (2) refinement of the PA-SAE scoring system; (3) development of a profile of the PA profession based on the results of an examination of a representative national sample of physician assistants; (4) completion of 18 self-paced learning modules based on the results of the PA profile; and (5) design of a continuing competency assurance program. The project has resulted in the production of a viable model for a continuing competency assurance system for physician assistants. To date, 12 learning modules have been completed and 6 more are currently being developed. Recommendations emerging from the project included calls for further consideration of the adequacy of the examination with regard to standards-setting and for development of similar systems for other health professions.
