This resource document presents four papers that were prepared by members of the Task Force on Institutional Effectiveness of the Council on Postsecondary Accreditation concerning issues related to assessments of institutional effectiveness and the use of assessment in the process of institutional accreditation. The first paper, "Outcomes Assessment, Institutional Effectiveness, and Accreditation: A Conceptual Exploration" (Peter T. Ewell), deals with some of the basic principles and issues involved in the use of outcomes assessment in accreditation, explores some of the tensions and alternatives these create, and develops recommendations for resolution. The second paper, "Incorporating Assessment into the Practice of Accreditation: A Preliminary Report" (Ralph Wolff), reports the results of a survey of those responsible for assessment activities including their practices, their level of knowledge of assessment issues, and their perception of the effectiveness of their current outcomes assessment practices. The third paper, "Methods for Outcomes Assessment Related to Institutional Accreditation" (Thomas Hogan), reviews the various methods of outcomes assessment and discusses their advantages and limitations. The last paper, (Trudy W. Banta), represents a selected 62-item bibliography of articles and documents about outcomes assessment in higher education. (GLR)
