The Guaranteed Student Loan Program, authorized by the 1965 Higher Education Act (Title IV-B) is intended to provide students with a means of financing part of the cost of education. The principal of the loan is provided by commercial lending institutions or state lending agencies. An increasing number of issues have surfaced regarding the program as a whole and certain specific aspects of it: (1) federal costs have increased steadily; (2) the extent of future federal liability implicit in new or issues loans is not precisely known; (3) default rates have increased to a level far beyond those that had been expected; (4) because lenders are reducing or eliminating their financial participation, it is not clear that GSLP can fulfill its objective of providing a major part of the financial assistance to college students; and (5) the program's social efficiency and equity are questioned by the high default rate for certain demographic groups and types of schools. Two questionnaires were developed, one concerning individual borrowers and one concerning lenders. Data collected add considerably to the limited base of knowledge about the student/lender process.
