The way that the participation of trustees in the processes of voluntary accreditation can help them in overseeing institutional autonomy and integrity is discussed, based on the work of a subcommittee of the Association of Governing Boards of Universities and Colleges. In addition, recommendations for board participation in institutional and specialized (programmatic) accreditation are offered. It is noted that accreditation is a means of accomplishing a major part of the central business of the boards for undertaking institutional planning and periodic evaluation. Attention is directed to the need for maintenance of high standards and the safeguarding of the integrity of self-regulation. Recommendations include the following: board members should be informed of the history, current practice, and strengths and weaknesses of their institutional accrediting associations; board members should actively participate in institutional self-study; the board should be informed of the objectives and activities of the visiting team and should meet with the team; the board should review the team's final report and help implement approved recommendations; and board members should join administrators, faculty members, and representatives of the specialized agencies in the periodic review of specialized accreditation practices.
