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…

Using Otis-Lennon Mental Ability Test, Elementary II Level and WISC Verbal Performance and Full Scale IQs of 40 white children, correlations of .71, .57 and .73, respectively, were computed. Results suggest IQs and should be interpreted with caution when used as criterion for identifying mentally retarded white children. (Author)

This study was concerned with determining the validity of the Slosson Intelligence Test (SIT) using the Stanford-Binet Intelligence Scale (S-B), Form L-M as the validity criterion. The sample consisted of 724 students enrolled in 10 public school systems in northeastern Massachusetts. Using the Pearson-Product Moment formula a coefficient of…

Because WISC users will inevitably need to shift from the WISC to the WISC-R, further research is needed to demonstrate the comparability of these two forms (and norms) of basically the same test. The present study provides data on EMR child children in the 12-1/2 to 14-1/2 year age range. (Author)

The paper reviews WISC/WISC-R comparison studies which have been conducted with a wide variety of samples. Caution is advised in the interpretation of a WISC/WISC-R difference, as a discrepancy of one SD may not be meaningful. (Author)

The impact of the Stanford Binet Fourth Edition was compared with the Stanford Binet L-M on the identification of gifted children for a university affiliated preschool. The fourth edition test composite identified fewer preschool age children as gifted when the criterion was set at 1.5 standard deviations above the mean. (Author/JDD)

Timed and untimed scoring methods were employed with five WAIS subtests administered to 40 young and 40 old subjects matched for verbal intelligence. Elimination of bonuses for rapid performance differentially improved the scores of older subjects but did not raise those scores to levels achieved by the young. (Author)

Reappraises the validity and reliability of Vocabulary and Block Design (V-VD) as a short form of the Wechsler Adult Intelligence Scale (WAIS), the Wechsler Intelligence Scale for Children (WISC), and the Wechsler Preschool and Primary Scale of Intelligence (WPPI). Presents a table for converting the sum of scaled scores into an estimate of Full…

Analysis of the variables measured on the General Aptitude Tests Battery and the Metropolitan Achievement Tests indicates that while achievement ratings are related to in-school and post-school success, aptitude testing may not be as effective a method as believed for vocational placement. Extensive literature review. Data tables. (CJ)

Reviews some better known Piagetian scales; analyzes and compares Piagetian-based and conventional intelligence measures. Reviews research comparing the two methods and examines whether racial groups' performance differs on Piagetian measures. Discusses the implications of Piagetian assessment procedures for school psychologists. (Author/RC)

Children and adolescents who had positive Dye Tests for toxoplasmosis had lower performances on all verbal subtests than those with negative Dye Tests. The impairment was comparable to subjects with brain damage. Subjects with congenital sight deficiency and positive Dye Tests showed progressive intellectual impairments. (Author/CM)

Findings do not reveal clinically significant differences between intellectually delayed and primary reading disabled children. Further exploration into cognitive and learning processes that relate more specifically to the child's difficulties is recommended. (Author)

A comparison of bilingual Puerto Rican students' scores showed no significant differences between the Full Scale and the Verbal Scale scores on both tests, but significant differences between the Verbal and Performance Scale scores on both tests. Caution in testing bilingual children before determination of bilinguality is recommended. (Author)

Correlations of WPPSI IQs with concurrently administered subtests from the WRAT were compared with analogous WISC-R/WRAT correlations in a group of children referred by regular classroom teachers for school psychological services. Results support the use of the two instruments as equivalent predictors of achievement. (Author)

Assessed test bias on the Wechsler Intelligence Test for Children-Revised (WISC-R) and Bender-Gestalt. On the Bender, evidence of bias was infrequent and irregular. On the WISC-R, group differences were most discernible for age, sex, family structure, and race. Consistent patterns of bias were not apparent among comparison groups. (Author)
