Examines practices that encourage false negatives and false positives on licensing and certification tests designed to protect the public. Recommends increasing the amount of testing or raising the required passing score for repeat test takers. (FMW)

The accuracy of 3 developmental screening tests administered to 89 young children was compared. The Battelle Developmental Inventory Screening Test was more accurate than the Academic Scale of the Developmental Profile-II and the Denver-II, identifying correctly 72% of children with difficulties and 76% of children without diagnoses.

The psychometric characteristics of 12 adults with Prader-Willi syndrome (PWS) and a group without PWS but with other similar traits were compared. Results found cognitive, behavioral and educational traits often associated with PWS to be present in both groups, illustrating the importance of control/comparison groups in research establishing…

This study used the Assessment Standards of the National Council of Teachers of Mathematics to evaluate the appropriateness and adequacy of selected standardized tests of mathematics achievement as they pertain to students with disabilities. Problems with content validity included inadequate representation of content domains, inappropriate…

This article discusses issues and difficulties encountered in efforts at the University of Birmingham (England) to standardize a new psychometric assessment tool, a tactile speed-of-information-processing test for children with blindness. The problem of defining the population on which the test is standardized is seen as particularly difficult.…

This article describes errors resulting from use of standardized language tests using a "normal" sample as the normative comparison group. Resulting errors include, among others, identifying normal children as language impaired, providing misleading profiles of verbal and nonverbal performance, and inability to determine impairment severity.…
