Universal screening of very early school-age children (age 4-7 years) is important for early identification of learning problems that may require enhanced learning opportunity. In this context, use of standardized instruments is critical to obtain valid, reliable, and comparable assessment outcomes. A wide variety of standardized instruments is…

Periodic assessment and scrutiny of the discipline's measurement practices, instruments, and research findings are necessary to provide clarity and direction by revealing what we know, how we know it, and where the knowledge gaps exist. Reflective reviews have produced ample appraisals of the theory, research, and methods employed in the conduct…

Direct support persons (DSPs) often face problems in observing and determining alertness in individuals with profound intellectual and multiple disabilities (PIMD). A literature study was carried out to gather information about the problems just described. A search of two electronic databases and the references found in relevant hits revealed 42…

Summarizes state-of-the-art approaches for assessing visual stimulus same/different judgments in individuals with severe intellectual disabilities. Methodological investigations indicate that one can obtain reliable same/different judgments with a variety of stimuli in virtually anyone for whom a basal score on the Peabody Picture Vocabulary Test…

Investigates the general factor and uniqueness characteristics of the individual tests of the Woodcock-Johnson Test of Cognitive Ability-Revised (WJTCA-R). Only 2 of the 19 WJTCA-R tests examined had low general factor loadings, while 2 had low uniqueness. All other tests had medium or high uniqueness. Discusses implications for clinical…

The primary goal of this review is to acquaint developmental psychologists who have had little experience in the study of individual differences in cognition with some of the basic rules that govern this type of research. A second goal is to stimulate researchers to consider the potential benefits of studying differences among individuals whose…

This article investigates cognitive decline and depressive symptomatology among older adults with mental retardation. A pilot study of assessment instruments is reported. Findings reveal that decreasing cognitive ability is associated with higher rates of observed depression and reported behavioral problems. Cognitive decline was associated with…

Discusses changes in testing as a result of the availability of extensive inexpensive computing and some recent developments in statistical test theory. Describes the role of the Computerized Adaptive Test (CAT) and modern Item Response Theory (IRT) in ability testing tailored to each student's knowledge and ability. (JAC)

Conference speakers reviewed and analyzed the current thinking underlying the basic concepts of test norms, reliability, and validity. Roger T. Lennon's paper called for more attention to the development of norming theory and summarized current norming practices and the establishment of a system which would permit comparable norms for tests which…
