Fifteen data tables are presented, indicating the average scores of college-bound seniors from Massachusetts on several College Board tests: the Scholastic Aptitude Test (SAT), Test of Standard Written English, Achievement Tests, and Preliminary Scholastic Aptitude Test/National Merit Scholarship Qualifying Test (PSAT/NMSQT). Selected data on student characteristics and a comparison of Massachusetts students to the national average are also included. Ten conclusions are reached, including: (1) Scholastic Aptitude Test scores have declined from 1971-72 to 1976-77, with greater decline in the mathematics than verbal tests; (2) males scored slightly higher than females on the SAT-verbal and 40-50 points higher on SAT-mathematics; (3) a higher percentage of Massachusetts and New England students registered for the Admission Testing Program than the nationwide sample; (4) grade point averages of the top ten percent of state and nationwide students have risen; (5) Massachusetts students scored lower than the national sample on achievement tests, but all scores have risen; and (6) there were slight declines on the Test of Standard Written English and the PSAT/NMSQT. A one-page bibliography resource guide and a list of Massachusetts school systems and community types are appended. (GDC)
