The Annual Test Report, 1981-82 has been developed as a reference on the results of the California Achievement Tests (CAT) in the Montgomery County Public Schools (MCPS). The report contains several analyses of the results from the CAT administration in Grades 3, 5, 8, and 11. Overall countywide results are presented and they are also broken down by racial/ethnic and sex classifications. School results are presented in four forms: (1) average subtest scores, (2) total battery interquartile ranges, (3) longitudinal trends (average score change for students tested in the same elementary school twice), and (4) nonlongitudinal trends (difference between average scores for students transferring into and out of each school). There are two appendices. The first one contains tables with detailed summary data. The second one is a glossary of technical testing terms which provides the definition, use(s), and some interpretive precautions to be observed for each term. (Author)
