This report is designed to provide the Norwalk (Connecticut) Board of Education and the entire school community with the status of the school system testing program for the spring of 1987. From May 6 through May 15, the system administered the Comprehensive Tests of Basic Skills (CTBSs) and the Test of Cognitive Skills (TCS) to 5,113 students in grades 1 through 8 (out of a total enrollment of 5,393). The CTBSs cover mathematics, language, reading, word attack, spelling, and reference skills. The TCS assesses students' skills in recognizing patterns and relationships, classifying objects, drawing conclusions, and remembering material. The TCS also assesses the students' probable achievement on the CTBS. The report covers test instruments used; analysis of test results; spring 1987 results by grade level; measurement units; the relationship of achievement to aptitude; use of results by instructional supervisors; and mathematics, language arts, and reading test summaries. Normal curve equivalents are used to examine progress over time. The students performed above the national median in mathematics at all grades except grade 3, and a positive trend in mathematics achievement for the study sample was found. Total language scores tended to be higher than total reading scores, and results for spelling and reference skills were fairly consistent. Twenty-eight bar graphs and 14 data tables are presented.
