The Comprehensive Tests of Basic Skills, Form U, is scored in two ways: number-correct and pattern. The latter makes use of the information about which particular items are answered correctly, giving more weight to the more discriminating items and making allowances for guessing. Critics have suggested that black students are penalized by pattern…

Item bias, when present in a multiple-choice test, can be detected by appropriate analyses of the persons x items scoring matrix. Five related schemes for the statistical analysis of bias were applied to a widely used, primary skills multiple-choice test which was administered in either its English- or Spanish-language version at each of the two…

Item bias in a multiple-choice test can be detected by appropriate analyses of the persons x items scoring matrix. This permits comparison of groups of examinees tested with the same instrument. The test may be biased if it is not measuring the same thing in comparable groups, if groups are responding to different aspects of the test items, or if…

Potential sources of bias in dual language achievement tests were identified and examined. Content, concepts, and vocabulary presented in monolingual English curricula may differ drastically from those presented in bilingual curricula. The Spanish or English versions of the Comprehensive Tests of Basic Skills (CTBS) were administered to 1259…

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)

The testing of bilingual students poses particular problems for analyses of performance, item bias, and test adequacy. A test administered in two languages to children selected for their language facility provides a special arena for the study of these problems. The Comprehensive Tests of Basic Skills (CTBS) was selected because the test content…

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)

The effects of the use of computer-enhanced instruction with remedial students were assessed, using 4,293 ninth through twelfth graders--3,308 Black, 957 White, and 28 Other--involved in the Governor's Remediation Initiative (GRI) in Georgia. Data sources included the Comprehensive Tests of Basic Skills (CTBS), a data collection form developed for…
