The following five standardized achievement test batteries commonly administered to pupils in grades 7-9 were…

This study attempts to detect the presence of either of 2 different categories of large-scale bias in 4 widely used mathematics achievement tests: induced bias and norming bias. Subjects were 407 eighth graders. (IAH)

When a program evaluation is conducted on the basis of gains made in standardized achievement test scores between a pretest and a posttest, serious bias can result where a floor effect exists on one or both of the test levels. Based upon the expanded standard scores on the Comprehensive Tests of Basic Skills from three successive regular spring…

It is unsafe to estimate achievement test norms for fall testing by linear interpolation between norms for the previous spring testing and norms for the following spring. Second grade students were tested in reading and arithmetic in the fall and in the spring to provide pre-test and post-test data for evaluation of academic growth. Three…

The Anchor Test Study (ATS) yielded equating tables for vocabulary, reading comprehension, and total reading scores for eight commonly used reading tests at the 4th, 5th, and 6th grade levels. Because of the original ATS sampling design which resulted in a nationally representative sample of school children at those grades, the equating tables…

American school officials almost invariably compare local and national achievement through one of the following norm-referenced tests: (1) the California Achievement Test; (2) the Stanford Achievement Test; (3) the Metropolitan Achievement Test; (4) the Science Research Associates Test; (5) the Comprehensive Test of Basic Skills; and (6) the Iowa…

Describes a system employed by a middle school to improve performance scores on the Comprehensive Testing of Basic Skills (CTBS), through aggressive attitude changes, to ensure fiscal and other benefits. Notes characteristics of the approach, including realistic goals, student involvement, student responsibility, community involvement, student…

Fourth, seventh, and ninth grade students in Elementary Secondary Education Act (ESEA) Title I programs were tested with the reading comprehension subtests of the Comprehensive Tests of Basic Skills, at each of two levels: on-level for each respective grade, and an easier out-of-level form. Approximately half of these students were found to be…
