This report presents results for Montgomery County (Maryland) Public Schools (MCPS) high school students on four tests of the College Board in the 1983-84 school year. These tests, ordered by the number of MCPS students taking them, are the Scholastic Aptitude Test (SAT), the Preliminary Scholastic Aptitude Test (PSAT), the Achievement Tests (ACH), and the Advanced Placement Tests (AP). A summary of the results across all of the tests includes the following: (1) average scores for MCPS students on College Board tests were well above national averages; (2) students showed improvements from the already high score levels of the previous year; (3) White and Asian students generally averaged substantially higher than Hispanic and Black students; (4) White and Asian students generally averaged well above the overall national average for all students; (5) all major racial/ethnic groups averaged well above their national counterparts on the SAT and ACH tests; and (6) substantially higher percentages of Asian and White students took College Board tests than did Black and Hispanic students. The remainder of the report is divided into four sections, one for each set of tests. Each section is a description of the test(s) and a presentation of results for the total county and results broken down by race, sex, and grade. (LMO)
