The results of this study indicate that the WISC-R IQs are good predictors of achievement. They predict general achievement as represented by the PIAT total score and achievement in specific areas including reading recognition, mathematics, and spelling as measured by the PIAT. (Author)

Compared were subtest scores and full scale results on the Wechsler Intelligence Scale for Children of 197 retarded (IQ 30-69) 7-to 15-year-old children. (CL)

The problem investigated in this study was to determine the best combination of tests or subtests in a research battery which, when administered to beginning first-grade students, would enable the most efficient prediction of reading achievement. A total of 1052 children were randomly selected from first-grade classrooms within the State of…

Data from a variety of infant intelligence scores make clear that it is not possible to consider (1) that infant intelligence is a measurable, stable and unitary construct, (2) that there is a general g factor easily discernible in infancy, (3) that there is stability of scores both within and across scales, or (4) that there is predictability…

The article describes a kind of intelligence testing which assumes that the potential of a "retarded performer" may be greater than his demonstrated knowledge, and therefore tests him in the process of learning. (CD)

Discusses the difficulties that arise when tests designed for one purpose are used for another. Points out that tests reflect the characteristics of the institutions that use them and emphasizes the need for more careful design of actual instructional programs as well as of the tests intended to assess learning. (Author/GC)

The Learning Potential Assessment Device and Instrumental Enrichment are two much needed improvements in education. Used in tandem, they rectify previous problems of testing and teaching by providing an unbiased assessment device which does not rely on labels for categories of learners. (VM)

The relationships between classroom performance, ability measures, paired-associate tasks, problem solving tasks, and CART scores are investigated for Grade 5 students. The test is standardized on Grades 5-8. (DG)

Revision of a paper presented at the National Convention of the Council for Exceptional Children, St. Louis, April 1967. (Author)

Investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test using the factor scores of the Wechsler Intelligence Scale for Children-Revised as potential predictors. Results indicated that the freedom from distractibility factor score significantly aided in the prediction of reading and spelling…

We evaluated the predictive accuracy of short forms of the Wechsler intelligence scales for individuals with high functioning autism. Several short forms were derived from participants who had received the full procedure. Stepwise multiple regression analyses were performed to determine the strength of association between the subtests included in…

This study analyzed and tested the equivalence of Forms A and B of the California Critical Thinking Skills Test (CCTST). In designing the CCTST, Form A was composed of 34 items from a bank of 200. To develop a parallel measure, Form B was developed by rewriting 28 of the 34 items and rearranging their order. Study participants were all entering…

The claim that tests of intelligence and abilities are the best predictors of academic success fails to examine closely the important moderator variable as test and criterion characteristics rather than as person characteristics. (EH)

The general ability factor (G), as enunciated by Charles Spearman in the model of cognitive functioning, has been the foundation of psychometric theory and test making practices for 80 years. Through these decades, some psychologists disagreed with this theory, especially Godfrey Thompson and E. L. Thorndike. Nevertheless, various aptitude tests…
