Fifty-seven primary-level students completed the Detroit Tests of Learning Aptitude-Primary: Second Edition (DTLA-P:2) and the Woodcock-Johnson Psycho-Educational Battery, Part I and II. A strong relationship between the two provides evidence for the criterion-related and construct validity of the DTLA-P:2 test scores. (Author/JDD)

The Cognitive Levels Test (CLT) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) were administered to 30 freshman college students at a small state college in the mid-Atlantic region. Significant correlations indicate that the PPVT-R measures a component of the CLT. Mean PPVT-R scores were significantly higher than CLT means. (Author/PB)

Rasch calibration procedures were applied to item-response data for the 1,262 infants and toddlers comprising the standardization sample for the Mental Scale of the Bayley Scales of Infant Development. Analyses tend to confirm the psychometric integrity of the instrument. (Author)

Thirty-two preschool children were administered the Cognitive Levels Test (CLT) to evaluate its temporal stability and concurrent validity. Results indicated good temporal stability for the CLT-Cognitive Index and high correlations between the CLT-Cognitive Index and the Stanford-Binet: Fourth Edition. (Author/JDD)

This study, involving 70 intermediate grade students, found that scores on the Matrix Analogies Test-Short Form (MAT-SF) were significantly lower than all of the Comprehensive Test of Basic Skills (CTBS) composite scores. The MAT-SF correlated significantly with all areas of the CTBS composite and spelling scores. (Author/JDD)

This study, with 66 regular classroom children and 52 children with learning disabilities, found high correlations among the Cognitive Levels Test, the KeyMath-Revised measure, and the Woodcock Reading Mastery Tests-Revised. Overall, 81 percent of subjects were correctly classified using the three-instrument battery. (Author/DB)

Twenty-two children with mild mental retardation, 27 children with learning disabilities, and 49 nondisabled peers (ages 4-5) were presented with a battery of eight cognitive tasks being considered for inclusion in a new screening test. Results found the components measured different cognitive tasks and led to accurate individual classification…

The Stanford Binet Intelligence Scale measures four areas of cognitive abilities (verbal reasoning, abstract/visual reasoning, quantitative reasoning, and short-term memory), providing a continuous scale for appraising cognitive development from age two to adult. This paper describes the test's administration, standardization, reliability, and…

The Woodcock-Johnson Psycho-Educational Battery-Revised is a set of tests designed to measure cognitive abilities, scholastic aptitude, and achievement in the areas of reading, mathematics, and written language, in individuals aged 2-95 years. This paper describes the test battery's administration, scoring, standardization, reliability, and…
