Multiple accreditation of individual institutions can involve serious duplication of efforts by accreditation agencies. Four examples of guidelines and procedures for cooperative accreditation are given: those of (1) the Western Association of Schools and Colleges and the Association of Theological Schools (a coordinating agreement with another accrediting agency); (2) The Association of Theological Schools and the New England Association Commission on Institutions of Higher Education (procedures for joint evaluations); (3) the American Home Economics Association/Foundation for Interior Design Education Research and the American Dietetic Association (mechanisms for exchanging information and scheduling joint site visits); and (4) the Council on Education for Public Health and the Accrediting for Health Services Administration Commission on Education (joint evaluation team visits). Guidelines developed by the Council on Postsecondary Accreditation's Task Force on Interagency Cooperation are also included. Suggested readings and a list of task force members are appended. (MSE)
