A summary report of the available literature on research in the principal components of Higher Educational Opportunity Programs, (HEOP) i.e. curriculum, instructional techniques, admissions policies, and others. This paper focuses on the discussions of HEOP's organizational format, materials, innovative educational techniques, and philosophies or theories of learning which have significant impact on student performance. A secondary focus is the identification of studies that have been done on the parts of the HEOP programs, individual counseling, tutoring, testing, and other supportive services aimed at academic development of the students. This report also identifies evaluative studies of Higher Educational Opportunity Programs which explore the degree of success and effectiveness of the program. Bibliographies are provided for sections on curriculum and instruction, tutoring, counseling, testing, and instructional program policies. The dilemma for these programs is held to be in how to produce substantial evidence of their contribution when their funding does not provide for this sort of research. (Author/AM)
