This paper describes the Loyola Center for Educational Improvement's (LCEI) effort to develop a clearinghouse on mastery learning (CML) which would serve as a depository for conceptual and research documents on mastery learning, competency-based education, instructional design, and other related topics. The nature of the clearinghouse is defined and the following projected activities are identified: (1) to update and expand the database searches, (2) to acquire relevant documents, (3) to analyze relevant documents using multiple dimensions for coding and computer retrieval purposes, and (4) to generate and disseminate information analysis products.
