Curriculum Inventory and Reports (CIR) is designed to serve as the premier benchmarking and reporting tool on content, structure, delivery, and assessment of medical school curricula. The Curriculum Inventory serves as the centralized database of AAMC-member medical school curricula, including content, structure, delivery, and assessment in the U.S. and Canada. Curriculum Reports provide graphical interpretations of both aggregate and historical curriculum-related data that: assist in curriculum benchmarking and continuous quality improvement; provide resources to curriculum committees and faculty; enhance medical education research; and inform legislators and the general public.
