The developer of the Comprehensive Tests of Basic Skills scaling responds to Hoover's attacks on Thurstone and item response theory scales (TM 510 173). While agreeing that grade equivalent (GE) scores are presently the most appropriate developmental score for reporting elementary grade achievement tests, limitations and inconsistencies in the GE…

Extended caution indices (ECI) specify the degree of confidence that can be placed in an individual's test score by analyzing patterns of item response. Among the most promising of such indices are the standardized ECIs. Contrary to the literature, several instances were found, in a previous study, of nonnormal distributions of ECIs with samples…

Grade equivalent (GE) scores for elementary school achievement tests are defended in response to efforts to ban their use. Equal interval developmental scoring methods for the Sequential Tests of Educational Progress and the Comprehensive Tests of Basic Skills are criticized. (BS)

The author addresses issues raised by Burket (TM 510 174) about the Iowa Test of Basic Skills scaling procedures. Further reasons for his criticism of Thurstone scale scores and item response theory scale scores for elementary school achievement tests are given. (BS)

Test anxiety scores from a 15-item internally consistent instrument were correlated with performance on an aggregate science test administered to 171 fourth- and 187 eight-grade students subdivided by sex and race. The interpretation of data possibly suggest that test anxiety is operating differentially for black and white students. (Author/PN)

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…

The primary purpose of the 1983 Statewide Testing Program was to assess the achievement of 4th, 7th, and 10th grade students in South Carolina public schools. The results from the Statewide Testing Program provide educators with information which facilitates the decision-making process at the State, district, and school levels. Besides the…

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…

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…
