The Ability-Achievement Model is reviewed for efficacy in comparison to the Response to Intervention Model when diagnosing students with possible learning disabilities. The research will address the success of Ability-Achievement Model versus the Response to Intervention Model when successfully diagnosing students with learning disabilities was…

Assessed the degree of comparability between the tests over time for two samples of referred adolescents of borderline intelligence. Results indicated that the Wechsler Adult Intelligence Scale-Revised significantly overestimated the Wechsler Intelligence Scale for Children-Revised by three to five points. Differences were most marked at the lower…

Studies of the reliability, normative data, construct validity, and concurrent validity of the Social Perception Behavior Rating Scale used with mildly learning-disabled, behavior-disordered, and nondisabled children indicated adequate reliability, marked differences in scores of handicapped and nonhandicapped children, and a logical pattern of…

This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

Ability-achievement discrepancies were analyzed using the Woodcock-Johnson Psycho-Educational Battery, WISC-R, and the Peabody Individual Achievement Test administered to a sample of low achievers. Reliabilities of difference scores were moderately high. Reliabilities of differences for devices normed on both the same and different populations…

A reliable instrument was developed to identify elementary-age children who have difficulty with time estimation, as indicated by choices on a pencil-and-paper test. The instrument was used to compare performances of learning disabled and nondisabled children. Findings provide empirical support for temporal difficulties among learning disabled…

The reliability of four measures of written expression was examined (total words written, mature words, words spelled correctly, and letters in sequence). Subjects included elementary-age students in several school districts, some of whom were learning disabled. Results revealed high coefficients for test-retest reliability, parallel-form…

The performance of disabled and non-disabled students on college admissions test were compared. Performance of learning disabled and hearing impaired students appears most discrepant from the norm. Evidence relating to validity and reliability of admissions tests for handicapped and nondisabled examinees suggests no dependable differences in…
