We compared the Wechsler scores of individuals with twice-exceptionality (2e) and giftedness using a three-level Bayesian meta-analysis. Ninety-five effect sizes were calculated from 15 studies (n = 2,106). Results show that individuals with 2e who have learning disabilities perform lower than individuals with giftedness in Full-Scale Intelligence…

The "Woodcock-Johnson III" Tests of Achievement grade norms versus age norms were examined in the calculation of discrepancy scores in 202 college students. Difference scores were calculated between the "Wechsler Adult Intelligence Scale-3rd Edition" Full Scale IQ and the "Woodcock-Johnson III" Total Achievement,…

Much has been written about gifted students with learning disabilities, but there have been few large-scale empirical investigations, and the concept has proven controversial. The authors reviewed the available empirical literature on these students, focusing on (a) the criteria by which the students were identified and (b) the students'…

This study examined whether a large group of postsecondary students participating in a support program for students classified as having learning disabilities (LD) met criteria for five objective diagnostic models for LD: IQ-achievement discrepancy (1.0 SD, 1.5 SD, and greater than 2.0 SD) models, a "Diagnostic and Statistical Manual of…

This study examined the validity of using teacher-administered educational and intelligence tests to screen students for learning disabilities (LDs). Twenty-seven Technical and Further Education (TAFE) students from regional Victoria who were enrolled in a program that was designed to reconnect school dropouts with education via TAFE participated…

Background: Whether the Flynn effect (the increase in the populations' IQ over time) affects the IQ scores of people with learning disability or borderline learning disability remains unclear. The issue is important as the Flynn effect should alter the number of people eligible for health service resources. A comparison of the Wechsler Adult…

This article documents the eligibility procedures and student assessment result of a project for identifying university students with learning disabilities. Many legal issues are relevant in the classification of young adults with disabilities, including the use of standardized procedures for establishing disability status which are meant to…

A study examined the identification of distinct subgroups of learning-disabled young adults based on their ability to generate written language. Two subgroups of learning-disabled college students, the language strong/visually weak (N=22) and the visually strong/language weak (N=10), were identified based on evaluation of 32 essays. Subjects were…

Professional assessment of mental retardation (MR) and learning disabilities (LD) is crucial to the implementation of P.L. 94-142 because it necessarily precedes the employment of trained teachers and because a plan for remediation depends on accurate assessment. Intelligence is a key element in the identification of MR-LD, but competent, fair…
