The Comprehensive Tests of Basic Skills (CTBS) battery are administered in New Mexico school districts as part of a state mandated assessment program. The tests are administered to students in grades three, five, and eight to measure achievement in the basic skills areas of reading, language, and mathematics. This report contains various types of test data which are to be used for the modification of the basic instructional program in the Albuquerque Public Schools (APS). The CTBS, Form U and its subtests are described. The 1984 test results for individual APS schools and average percentile ranks across the district are presented in graph format. Test scores for each grade level of APS students are better than student scores in the national norming population on every content area subtest. Average percentile scores compare the performance of APS students to the national norm group; the range of average performance is from the 40th to 60th percentiles. School by school data show the percentage of students in the below average, average and above average ranges in the CTBS major content areas. Student attendance and mobility rates for each school are included since these factors may impact group performance. (DWH)
