Due to a concern regarding the validity of Chicago public elementary schools standardized test scores on the Iowa Tests of Basic Skills, a test audit was conducted. The audit was limited to 40 schools. Two schools were selected from each of the 20 administrative districts, with each school testing one seventh- and one eighth-grade class. These…

The average grade equivalent reading comprehension scores of students in Black schools are compared to those of students in White schools under two forms of test administration. Concludes that use of grade level testing with the Iowa Tests of Basic Skills is biased in favor of low scoring subgroups. (Author)

This paper reports an investigation of inferencing in Form Five of the Reading Comprehension component of the Iowa Tests of Basic Skills. The first step in the investigation consisted of an analysis of the language of the test to determine how the inferencing strategies employed might serve to mask answers. This preliminary analysis suggested that…

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…

Three levels of a mathematics computation test were equated using the Rasch model. Sixth, seventh, and eighth graders were administered different levels of the test. Lack of consistency among equatings suggested that the Rasch model did not produce a satisfactory vertical equating of this computation test. (Author/RD)

Richard Rothstein's booklet "What Do We Know About Declining (Or Rising) Student Achievement?" claims that anecdotes about past educational practices are unreliable and difficult to relate to today's schools. Curricula and tests change; so do student populations. There are no solid historical measures, including three well-known…

When used appropriately, standardized assessments can assist education reform by tracking individual or group progress and achievement levels and indicating college readiness. Credibility and validity can be improved by preventing student exclusions, using multiple indicators, stressing year-to-year performance, monitoring consequences, and…

This research examines the effects of test format on achievement-test performances of Black children. Multiple-choice test items containing distractors (e.g., all correct, all incorrect) penalize Black children, since distractors appear to serve as blocking agents. The results also suggest that distractors encourage guessing. (Author/DOW)

A mathematics achievement test with instructions to avoid guessing wildly was given to 168 elementary school pupils who were later asked to complete all the questions using a differently colored pencil. Results showed examinees, particularly the more able students, tend to omit too many items. (CTM)

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…

Investigated the Mathematics Problem Solving (MPS) and Mathematics Concepts (MC) subtests of the Iowa Tests of Basic Skills for content and psychometric item bias at grades three, six, and eight. Identified items which favored either males or females. Found no skill classification, item content, or location trends. (Author/JAC)

Examines the extent to which kindergarten pupil and teacher behaviors during administration of the Iowa Test of Basic Skills--Early Primary Battery may compromise the meaningfulness and usefulness of the test scores. Although extensive variability in behavior was observed, most teachers followed directions exactly and most pupils encountered no…

The recent test score declines should initiate a reconsideration of basic and advanced skills, skills necessary for a rounded life, consumption, employment, leisure and political action. The importance of achievement test score declines requires a thorough consideration of these issues and questions. (JY) Aspect of National Assessment (NAEP) dealt…

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)

In certain situations, grade equivalent scores are the most appropriate statistic available for reporting achievement test data. It is noted that testing practitioners have found that raw scores, normal curve equivalents, stanines, and standard scores are very useful. However, it is best to convert to either grade equivalents or percentiles before…
