Data derived from the administration of the Canadian Chiropractic Examining Board (CCEB) examinations for a nine year period, 1987-1995, were used to evaluate the reliability and validity of the subject tests: anatomy, chemistry, chiropractic practice, diagnosis and symptomatology, microbiology and public health, neurology, pathology, physiology, and x-ray interpretation and physics. Nearly two-thousand candidates from more than eighteen chiropractic colleges have written the CCEB exams over this nine year period. The results indicate that the exams have adequate alpha reliabilities (.69 to .80) and theoretically appropriate statistical properties and item characteristics. There is also substantial evidence of content validity. Results from stepwise multiple regression and factor analyses provided evidence for the criterion-related and construct validity of the exams. The implication of these results for the continued refinement and development of the CCEB exams, together with suggestions for on-going research of their reliability and validity, are discussed.
