Appropriate interpretation of assessment data requires an appreciation that tools are subject to measurement error. School psychologists recognize, at least on an intellectual level, that measures are imperfect--that test scores and other quantitative measures (e.g., rating scales, systematic behavioral observations) are best estimates of…

The aim of the present study was to investigate the reliability and validity of a brief standardized assessment of children's working memory; "Lucid Recall." Although there are many established assessments of working memory, "Lucid Recall" is fully automated and can therefore be administered in a group setting. It is therefore…

This article is a one-year review of available research and an appraisal of the Revised Peabody Picture Vocabulary Test (PPVT-R). This instrument consistently demonstrates adequate alternate form equivalence across samples and consistently evidences significantly lower standard scores than its earlier version and traditional cognitive tests…

This assessment of the usefulness of the "Wechsler Preschool and Primary Scale of Intelligence-Revised" and the "Wechsler Intelligence Scale for Children-Third Edition" for gifted children found that both are technically superior instruments with sensitive items, exceptional standardization, strong construct validity, and…

Examines misclassification of Native Canadian students' abilities with standardized intelligence test results. Wechsler Intelligence Scale for Children-Revised (particularly verbal scale) results often reflect extent of acculturation, not personal capabilities.

Scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal, Performance, and Full Scales were compared for 26 adolescents with educable mental handicaps. The WAIS-R, while strongly correlated with the WISC-R, provided higher scores on all three scales. Several WISC-R…

The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…
