The Connecticut Assessment of Educational Progress (CAEP) is a continuing program designed to measure the efficiency of educational programs offered by public schools. During 1979-80, grades 4, 8, 11 were tested in science. The assessment goals were: to provide information on the quality of education in Connecticut; to collect and compare data with the 1974-75 science assessment information, gauge statewide progress and determine future policy; to compare Connecticut students' achievement with that of other students nationwide; for school districts to use assessment information to implement their own programs; to produce achievement tests measuring specified skills; and to produce student questionnaires which investigate attitudinal and other student variables which may relate to achievement. The first three chapters contain a summary of the design and methodology of the Science Assessment. Remaining chapters present questionnaires and achievement results for all three grade levels. Copies of the test instruments, along with computer results reports, appear in the appendixes. (Author/AEF)
