Each spring students in fifth, seventh and ninth grades in the San Diego City Schools complete a series of tests as part of the annual Districtwide Testing Program. The Comprehensive Tests of Basic Skills (CTBS) are used to measure student knowledge of various broad areas of the curriculum. This bulletin presents results of student achievement in reading, language, and mathematics for 1982 through 1985. The results are given in median percentile ranks and are illustrated by tables and graphs for each subject by grade level and school year. Short answers are given to the following questions which are frequently asked about testing in the district: (1) Does the CTBS measure everything taught in San Diego schools? (2) What is a "standardized norm-referenced achievement test"? (3) How does San Diego City Schools use the CTBS results to help students? (4) If a student scores below the norm in reading, does that mean he/she is a poor reader? (5) Wouldn't it be worthwhile to try to teach all students to perform at or above the national norm? (6) What test results are being reported for schools? (JAZ)
