Competency-Based Certification Project. Phase III: content validity, standard setting and criterion-related validity

This is the final article in a three-part series explaining the CAMRT's Competency-Based Certification Project--an effort to make the Association's certification process more job-relevant. The first article (Journal, August 1994) explained the job analysis process used to specify and validate the list of duties and tasks required of entry-level medical radiation technologists, the imaging and treatment procedures they perform, and the equipment they use. The second article (Journal, October 1994) explained the process for developing an examination blueprint by reviewing the CAMRT's examinations and summaries of clinical experience in the context of competency-based evaluation and the job analysis validation in each discipline. This article examines the development of assessment standards for certification examinations and summaries of clinical experience. It provides an overview of the steps necessary to develop a valid and defensible licensure/certification process after development of the examination content is complete.
