The summary reporting service of the College Board Admissions Testing Program permits groups of colleges to obtain group reports for Scholastic Aptitude Test (SAT) candidates from the most recent high school class who requested that their scores be reported to at least one college in the group (i.e. public four-year, private four-year, Catholic four-year, etc.). Similarly, high school group reports based on all SAT candidates from the given class attending high schools within specified groups (i.e. small city, suburban, large city, etc.) are produced. All school and college groups for which reports were produced both in 1971-72 and 1975-76 are included. The great majority of these groups exhibited declines in mean SAT scores over this period. With only a few exceptions, those groups showing increases in either SAT--verbal or SAT--mathematical mean scores had substantially smaller numbers of students in the more recent year. (Author/EVH)
