The Admissions Testing Program's (ATP) Summary Reports for the 50 states on information concerning 1979 college-bound high school seniors compose this collection. Information was obtained by student descriptive questionnaires, Scholastic Aptitude Tests, Achievement Tests, and the Test of Standard Written English. Areas examined were test scores, high school records, socioeconomic characteristics, intended college majors, college plans, and type of high schools producing the students. The purpose of the reports is to aid institutions in greater understanding of the factors involved with preparing high school seniors to enter postsecondary education. Additional information about the reports can be obtained by contacting one of the six regional offices listed on the back cover of each individual report. (LC)
