Evaluated correlations between Wechsler Intelligence Scale for Children-Revised, Woodcock-Johnson (W-J) Achievement clusters, Woodcock-Johnson Aptitude clusters, and Broad Cognitive Ability Score in 60 Behavior-Disordered male adolescents. Aptitude cluster scores had insufficient validity to justify computation for population; Broad Cognitive…

This study examined the performance of 48 students (mean age 10 years, 6 months) referred for evaluation of learning disabilities with the Wechsler Individual Achievement Test (WIAT) and the Woodcock-Johnson Psychoeducational Battery-Revised Tests of Achievement (WJ-R). The student sample consisted of 33 males and 15 females, all attended schools…

Thirty elementary students referred for possible learning disability were administered the achievement sections of the Woodcock-Johnson Psycho-Educational Battery and several traditionally used school district tests. Identical student placement decisions were reached on 23 out of 30 students. (Author/GDC)

The adequacy of the Woodcock-Johnson Psycho-Educational Battery, Part II: Tests of Achievement, for identifying and diagnosing learning disabled college students was examined using 68 subjects. Results indicated that ceiling effects were less pervasive than with regular college students. Cluster and subtest reliabilities proved adequate for use in…

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)

Comparison of scores of 35 third- and fourth-grade students with learning disabilities on 3 major achievement tests found high positive correlations among the reading subtests. Agreement across all 3 tests for learning disability eligibility in the basic reading skills area was found in 20 of 35 cases and 9 of 35 cases in reading comprehension.…

Performance of 100 college freshmen on the Woodcock-Johnson Psycho-Educational Battery, Part II, Tests of Achievement, were analyzed by subtests and cluster scores to determine appropriateness for assessing achievement of handicapped students. Minor inversions in item order and pronounced ceiling effects on all subtests yielded lowered subtest and…

The Woodcock-Johnson Psycho-Educational Battery is a wide-range comprehensive set of individually administered tests, with norms provided from the preschool to the geriatric level. Part one contains twelve subtests of academic ability and aptitude. Part two contains ten subtests measuring academic achievement. The final section measures scholastic…

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…

This study developed a normative core profile taxonomy of the four scholastic aptitude and corresponding achievement scales of the Woodcock-Johnson Psycho-Educational Battery (Revised). Cluster analysis was used to sort 2,620 students from the standardization sample. Results of internal and external validity analyses provided support for eight…

A two-dimensional, compensatory item response model and a unidimensional model were fitted to the reading and mathematics items in the Woodcock-Johnson Psycho-Educational Battery-Revised for a sample of 1,000 adults aged 20-39 years. Multidimensional information theory predicts that if the unidimensional abilities can be represented as vectors in…
