This sheet offers statistics and analysis of national data from the National Postsecondary Student Aid Study (1993) on the net costs of attending institutions of postsecondary education including tuition, fees, and living expenses minus grants, loans and work study compensation. One table shows costs of college attendance and student financial aid for dependent, full-time undergraduate students, by family income and type and control of institutions for the academic year 1992-93. This table also shows ratios of grants to tuition and fees and of net cost to total cost. These figures are provided for public four-year institutions, private four-year institutions, and public two-year colleges. A second table shows costs and student financial aid for dependent, full-time undergraduates, by type and control of institutions and family income for academic year 1992-93. Brief discussion of the statistics points out that: (1) among all dependent, full-time undergraduate students attending public four-year institution, average grant aid received was 29 percent of the average tuition and fees charged and that this ratio varied from 80 percent for students from low income families to 10 percent for those from high income families; and (2) the average net cost was 80 percent of the average total cost for dependent, full-time undergraduates attending public, four-year colleges.
