Policy changes at the federal and state level are endeavoring to improve student achievement at schools serving children from lower-SES homes. One important strategy is the focus on using evidence-based core reading curricula to provide a consistent framework for instruction across schools. However, rarely have these curricula undergone rigorous…

Administered the Stanford-Binet, Fourth Edition, to 31 mentally retarded adolescents who had previously been tested with the Stanford-Binet, L-M, with a mean interval between testings of 17.3 months. Found an intertest correlation of .86 and a median intelligence quotient change of three points in either direction. Compatability of scores supports…

Administered Stanford-Binet Intelligence Scale: Fourth Edition and Kaufman Assessment Battery for Children to 40 referred children. Correlation coefficients computed between two tests were strong, suggesting consistency in underlying global construct being measured; however, no compelling evidence supporting theoretical structure of two scales was…

Administered the Slosson Intelligence Test (SIT) to 92 preschool children. Administered the Stanford-Binet Intelligence Scale to a sample of the group, and the results were compared to the results from the SIT. Results indicated the SIT overestimated the performance of average preschool children. (Author)

Investigated factor structures of Wechsler Intelligence Scale for Children-Revised (WISC-R) and Kaufman Assessment Battery for Children (K-ABC) for 212 normal children. Findings suggest correspondence between: (1) WISC-R Verbal Comprehension and K-ABC Achievement; (2) WISC-R Perceptual Organization and K-ABC Simultaneous Processing; and (3) WISC-R…

Examined concurrent validity of Nonvocal Cognitive Quotient (NVCQ) of Cognitive Abilities Scale (CAS) and Stanford-Binet Intelligence Scale: Fourth Edition (Binet IV) for two and three year olds. Found adequate concurrent validity for CAS NVCQ and Binet IV Verbal Comprehension at both age levels as well as for Nonverbal Reasoning/Visualization…

Compared the Wechsler Intelligence Scale for Children (Revised) and the Woodcock-Johnson Psycho-Educational Battery (W-J) for 142 children with regular and learning-disabled (LD) class placement. The W-J and WISC-R evidenced low to moderate correlations and significant mean differences. W-J/WISC-R correlations for the regular students exceeded…

Examined concurrent validity of Stanford-Binet Intelligence Scale, 4th edition (SB IV) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) in a homogeneous, nonexceptional sample of 32 early elementary school children. Findings suggest that SB IV has significant positive relationship with WISC-R. The tests displayed a moderate level…

A study was conducted to ascertain whether use of an interpreter and/or a regular examiner in administering the WISC would affect test results of a group of Mexican-American children. Spanish administration of some scales of the performance test are likely to elicit optimum performance. (Author)

Examined whether common factor structure was evident in Wechsler Intelligence Scale for Children-Revised and Adaptive Behavior Scale-School Edition for 171 children referred for evaluation of learning and behavior problems. Results indicated no common factor structure in instruments, Verbal Comprehension, Perceptual Organization, Independent…

Investigated the external validity of the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) in learning disabled (LD) elementary school children (N=60). Results suggested that the WJTCA's achievement emphasis jeopardizes its validity for assessing and classifying LD students within the currently accepted and mandated ability-achievement…

Examined the relationship between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and Wechsler Intelligence Scale for Children-Revised (WISC-R) in a referral sample of 52 elementary students. Results showed comparable WJTCA/WISC-R global ability estimates, contrary to lower WJTCA scores found in recent studies with learning disabled…

Investigated validity of Stanford-Binet Intelligence Scale-Fourth Edition and Kaufman Assessment Battery for Children with 89 preschool Head Start children from low-income families, using Stanford-Binet Intelligence Scale-Form LM as criterion measure. Found some support for concurrent and construct validity of both instruments for use with…

The Peabody Individual Achievement Test was factor analyzed at five grade levels. Subtests composing each factor changed from the lower to upper grade levels, but abilities measured by each factor appeared constant. A close similarity between the two factors and Cattell's concept of fluid and crystallized intelligence was noted. (Author)

Investigated use of revised Slosson Intelligence Test (SIT) for screening public school students (N=131) for giftedness. Found revised SIT intelligence quotient (IQ) mean to be significantly lower than old ratio SIT IQ mean, significantly higher than Wechsler Intelligence Scale for Children-Revised and Stanford-Binet means. Advises caution in…
