This report contains a comprehensive listing of basic student charges for academic year 1990-91 at over 4,700 4-year, 2-year, and public less-than-2-year postsecondary institutions. Typical tuition and required fees are provided for in-state and out-of-state students at the undergraduate and graduate levels, along with the costs for room and board, and the number of meals per week covered by the board charge. Tables give summary national statistics on tuition and required fees for the academic year 1990-91 at postsecondary institutions. Data are also presented on tuition and required fees and room and board charges at individual institutions. These listings are divided into three sections: (1) 4-year institutions (offering a bachelor's degree or higher); (2) 2-year institutions (offering a postsecondary award of at least 2 but less than 4 academic years; and (3) public less-than-2-year institutions (offering a postsecondary award of less than 2 academic years). Schools are listed alphabetically by state within each section. Listings for schools in outlying areas, such as Puerto Rico, follow the state listings. At the beginning of each state listing are state averages for the various charges. A glossary presents definitions for 15 key terms. (JB)
