The Florida Statewide Assessment Program, defined by the 1976 Educational Accountability Act, collects and disseminates information on the effectiveness of its school systems to help its students achieve minimum performance standards (MPS) in mathematics, reading, and writing tasks. The 1980-81 regular assessment involved approximately 460,000 public school students in grades 3, 5, 8, 11, and 12. Students were tested on the State Student Assessment Test, Part I (SSAT-I), in October 1980. The State Student Assessment Test, Part II (SSAT-II), was administered to 10th grade students in April 1981. SSAT-I is a test of basic skills, while SSAT-II is a test of the application of the basic skills to practical solutions. The reliability and dependability of the tests were monitored through the use of the Kuder-Richardson Formula 20 index (coefficient) of reliability and the Brennan-Kane Index of Dependability procedures. The tests were judged to have high internal consistency reliabilities and high dependability indices. Mastery of MPS was fairly uniform across grade levels and subject areas. MPS criteria, number of skills and items, and descriptions of the raw score data are contained in the appendices. (Author/PN)
