The 1972 edition of the Program Classification Structure (PCS) is revised, using essentially the same framework but with additional categories and more detailed definitions. The PCS is a framework that permits the classification of a postsecondary education institution's resources and programs/activities as they relate to the accomplishment of institutional objectives. Programs may be assigned to eight categories: instruction, research, public service, academic support, student services, institutional support, independent operations, and student access. In each category, specific activities are categorized by subprograms. The PCS was intended as an instrument for organizing information, but has been used for objective-oriented planning and management at several institutional levels. (Author/MSE)
