System Development Corporation conducted an extensive project of conceptualization and planning of models for compensatory educational intervention for disadvantaged youth at the secondary and postsecondary levels. One of the initial steps in the planning process was the identification of components in programs presently being implemented in the Upward Bound and Special Services for Disadvantaged Students programs. Over 100 programs were examined. This index of currently successful components is intended as a reference guide, and will be updated. Categories of components in the index include: needs assessment, remedial language arts, remedial mathematics, support for high school study, postsecondary education orientation, guidance and counseling, and financial assistance.
