This report provides those who need to interpret scores on the Scholastic Aptitude Test (SAT) and the College Board Achievement Tests with information about college-bound seniors who have taken these tests. In addition, the report documents changes over time in the characteristics of students taking the tests. Information is based on the latest test scores and background data that these seniors have submitted. Mean SAT scores are displayed for different portions of the testing population using information from the Student Descriptive Questionnaire. Of particular interest is information on the students' academic preparation and the number of years of study in particular areas.

Information on the characteristics of students' high schools, based on a survey of high schools, is provided. Scores on the Test of Standard Written English and the Achievement Tests are summarized.
