This article defines test bias and reviews research methods most aptly applied postpublication to educational and psychological tests. Best methods for estimating bias in criterion-related or predictive validity and determining bias in construct validity across groups are explained. (Author/JDD)

The issues of construct validity, predictive validity, and item content bias on the Wechsler Intelligence Scale for Children-Revised (WISC-R) are examined. The review concludes that most objective data have not supported the issue of bias of the WISC-R when used with children of different ethnic backgrounds. (JDD)

This study examined the construct validity of the KeyMath-Revised by testing the factorial model proposed by the test author. Results failed to confirm the proposed factorial model and suggested that the KeyMath-Revised assesses two domains that are difficult to interpret, rather than the three proposed by the test author. (Author/JDD)

Reported discrepancies between the WJTCA (Woodcock-Johnson Tests of Cognitive Ability) and Wechsler Intelligence Test for Children-Revised (WISC-R), scores of normal, learning disabled, and emotionally disturbed children (n=60) were analyzed. Results confirmed the validity of the WJTCA general cognitive ability score and indicated subscale…

The response to a previous article by Mardell-Czednowski and Lessen notes the lack of common criteria for evaluating technical adequacy of assessment instruments used with handicapped children and stresses the need to evaluate instruments with the specific populations to which they are administered. (DB)

Special education tests evaluated by M. Thurlow and J. Ysseldyke with regard to technical adequacy were reevaluated using the same criteria. There was disagreement of 11 of the 30 tests used in both evaluations, demonstrating that current test standards are vague enough that experts disagree. (Author/CL)

Fifty-one gifted children, aged 9-17, were tested with the Stanford Binet Intelligence Scale, Fourth Edition, and the Peabody Picture Vocabulary Test-Revised. Correlations indicated that the Peabody may be of value in screening students being considered for gifted placement. (Author/JDD)

Content validity is an overriding problem in all measures evaluating written expression because there is no complete model of written language. Direct atomistic measures have greater instructional utility in diagnostic assessment, grouping, monitoring and decision making, reporting student progress, and giving feedback to students than do indirect…

Evaluation of mean score differences between the Stanford-Binet Intelligence Scale (Fourth Edition) and the Wechsler Intelligence Scale for Children (Revised) (WISC-R) for 126 children with academic difficulties found the Stanford-Binet composite score was significantly higher than the WISC-R score at the lower end of the ability continuum but…

The article explains standardization procedures used for the Illinois Test of Psycholinguistic Abilities (ITPA) and some of its technical characteristics as well as how such information should influence decisions for determining a child's need for special education. (Author/PHR)

Students in a midwestern public school gifted curricula (n=39) were tested using the Stanford-Binet (SB) Intelligence Scale: Fourth Edition. Correlations with scores from the Wechsler Intelligence Scale for Children-Revised and earlier SB scales were studied. Only the correlation between the SB verbal reasoning standard age scores and the Wechsler…

The usefulness of the picture story language test (PSLT) as a standardized assessment procedure that would discriminate between 124 nonlearning-disabled and 85 learning-disabled (LD) elementary school students was studied. It was concluded that the PSLT does not allow for an accurate and complete diagnostic appraisal. (Author/PHR)

The study compared performance of 135 children of three different ethnic groups (Black, Hispanic, and White) on the Minnesota Percepto-Diagnostic Test-Revised with age and IQ controlled. Results indicated no significant differences for the rotation T-score but significant differences in favor of Whites for the supplementary scores. (Author/DB)

A framework is presented for implementing standardized achievement testing. Fundamental concepts and formats of the tests are reviewed, and useful references are listed. Standardized tests are considered and categorized in terms of administration format, functions, validity, and type (cognitive versus noncognitive). Thirteen basic recommendations…

A study involving 120 school-aged children that investigated the concurrent validity of measures of written language found that the Wechsler Individual Achievement Test Written Expression subtest correlates moderately with the Written Expression subtest of the Peabody Individual Achievement Test-Revised and the Spontaneous Writing Quotient of the…
