By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

Administered Kaufman Assessment Battery for Children (K-ABC) and Stanford-Binet Fourth Edition (Binet IV) to 32 gifted third- and fourth-graders. Binet IV scores averaged eight points higher than K-ABC scores. Concurrent validity coefficient of .70 indicated high degree of association between test performance on two tests. Results support use of…

Compared area scores from short-form version of Stanford-Binet Intelligence Test (Fourth) with those from long form for 33 gifted children. Found three of five mean difference contrasts were significantly different and correlation coefficients between corresponding area scores and Test Composite were statistically significant. Suggests that…

Investigated power of five measures to differentiate between normal children and children with Attention Deficit Disorder or Specific Learning Disabilities. Discriminant analysis revealed that Connors Parent Questionnaire was best predictor of group membership, followed in order by Connors Teacher Questionnaire, Porteus Mazes Test, and Matching…

The criterion validity of the primary, elementary, and intermediate school forms of the Otis-Lennon School Ability Test (OLSAT) in an Australian context was studied. Results with about 8,000 children in grades 1 through 8 support the criterion validity of the OLSAT for Australian samples. (SLD)

Use of the Bender Visual Motor Gestalt Test in Australia was studied by comparing it with existing research, scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R), and other attainment tests. Subjects were 142 children aged 7-11 years. The suitability of the instrument in Australia is discussed. (SLD)

A factor analysis study was conducted of the Wide Range Assessment of Memory and Learning (WRAML), a test developed from a test structure model of memory and learning. The battery is composed of nine subtests (three verbal, three visual, and three learning subsets). The sample consisted of 903 students aged 5 years through 8 years 11 months, and…

Detailed evidence is presented about the extent of generalization from high-stakes tests to other tests and about the instructional effects of high-stakes testing. Data are from grade 3 of a large, high-poverty urban district with large numbers of Black and Hispanic American students. The district's results in 1990 for two tests, designated Test B…

Test scores on the Test of Basic Concepts, a school readiness test, were compared with actual performance in school for 186 low-scoring and 133 high-scoring groups of first graders from Spain at the beginning of the school year to explore the issues of competence testing and prediction of performance. The measure of school performance was derived…
