Assessing higher-level verbal repertoires of individuals with autism and related intellectual disabilities is crucial due to the language and cognitive deficits experienced by this population as well as is the need for valid assessment tools for data-driven and individualized treatment. In addition to, curricula or instructional protocols that…

This article examines the validity of IQ-achievement discrepancy and low achievement as criteria for the identification of disabilities in Spanish-speaking English-language learners (ELs) and the factors that moderate the validity of these approaches as bases for identification. While there has been a long history of examining the validity of…

This article examines the validity of IQ-achievement discrepancy and low-achievement as criteria for the identification of disabilities in Spanish-speaking ELs and the factors that moderate the validity of these approaches as bases for identification. While there has been a long history of examining the validity of different approaches to…

This study assessed the reliability and criterion-related validity of teacher ratings on the Adapted Skillstreaming Checklist for a sample of 133 children, aged 6-11 years, with autism spectrum disorder (without intellectual disability). Internal consistency for the total sample was 0.93. For a subsample, test-retest reliability was very good (r =…

Asperger syndrome (AS) patients show heterogeneous intelligence profiles and the validity of short forms for estimating intelligence has rarely been studied in this population. We analyzed the validity of Wechsler Intelligence Scale (WIS) short forms for estimating full-scale intelligence quotient (FSIQ) and assessing intelligence profiles in 29…

The aim of this work is to develop and investigate the model for assessing learning management on the enrichment science classrooms in the upper secondary education of the Development and Promotion of Science and Technology Talents Project in Thailand. Using the research methodologies with the four phases: to investigate the background of the…

In recent years, models of giftedness have incorporated personal and social variables which influence IQ, rather than taking IQ into account exclusively. Among the various options presented in this context, authors have proposed dynamic assessment techniques as a method for revealing the potential capacity in different groups, independently of the…

The purpose of this study was to examine the construct and predictive validity of a dynamic assessment (DA) of decoding learning. Students (N = 318) were assessed in the fall of first grade on an array of instruments that were given in hopes of forecasting responsiveness to reading instruction. These instruments included DA as well as…

Based on data from a sample of 106 students in grades 2 through 8, we explored the psychometric integrity of the Universal Academic, Cognitive, Creativity, Emotion Screening Scale (Universal ACCESS; R. S. McCallum & B. A. Bracken, in press). We obtained Cronbach's alphas ranging from 0.95 to 0.98 across the eight scales of the Universal…

A meta-analysis of the stability of low IQ (IQ less than 80) was performed on IQ tests that have been commonly used--tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997) and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-mean stability coefficients of 0.77 and 0.78 were found…

Robert J. Sternberg often writes about a lecture-style psychology course he took as a college freshman in which he got a C. "There is a famous Sternberg in psychology," the professor told him at the time, "and it looks like there won't be another." To Mr. Sternberg, the vignette illustrates that conventional assessments do not measure all the…

To promote efficient clinical practice, interest has been growing in brief assessment scales to replace full-scale versions in some circumstances. In nonclinical populations, the Wechsler Abbreviated Scale of Intelligence (WASI) has substituted for the Wechsler Intelligence Scale for Children--Third Edition (WISC-III). Agreement between these…

Because persons with mental retardation cannot be executed for murder, the diagnosis becomes a life and death matter. The American Association on Mental Retardation (now the American Association on Intellectual and Developmental Disabilities) and other associations agree that IQ alone is an insufficient criterion and adaptive functioning also…

This study, involving 1,069 children (ages 9-14) referred for evaluation of learning disability, used 3 definitions of reading disability to provide criteria for 5 groups of children based on discrepancy between intelligence quotient (IQ) and academic achievement. Results question the validity of segregating children with reading deficiencies…

This study analyzes the standardization sample of a new teacher rating scale designed to assist in the identification of gifted students. The Gifted Rating Scales-School Form (GRS-S) is based on a multidimensional model of giftedness. Results indicate no age or race/ethnicity differences on any of the scales and small but significant differences…
