Background: The reliability and validity of the Screener for Intelligence and Learning Disabilities (SCIL) are unknown in a population of outpatients with severe mental illness. The prevalence of mild or borderline intellectual disabilities (MBID); an umbrella term for people with borderline intellectual functioning (BIF) and mild intellectual…

The European Union has seen an increased number of asylum seekers and economic migrants over the past few years.

As a result of the upcoming Federal reauthorization of the Individuals With Disabilities Education Improvement Act (IDEA), practitioners and researchers have begun vigorously debating what constitutes evidence-based assessment for the identification of specific learning disability (SLD). This debate has resulted in strong support for a method that…

The Wechsler Intelligence Test for Children -- Fifth Edition (WISC-V) is a comprehensive intellectual ability assessment for children. The WISC-V was developed over the course of five years by an expert team including doctoral-level scientists and clinicians and an advisory panel, who provided expert advice about intellectual ability testing,…

The Culture-Language Interpretive Matrix (C-LIM) was developed to help practitioners determine the validity of test scores obtained from students who are culturally and linguistically different from the normative group of a test. The present study used an idiographic approach to investigate the diagnostic utility of the C-LIM for the Wechsler…

Students (n=210) in learning disabilities research centers were administered the Wechsler Intelligence Scale for Children-Revised and the Woodcock-Johnson Psychoeducational Battery-Revised. A model considering the reliability of each measure identified learning disabilities three times more often than a regression analysis model. The regression…

This study examined effects on 62 elementary students with learning disabilities undergoing triennial reevaluation of the change from the Wechsler Intelligence Scale for Children--Revised to the Wechsler Intelligence Scale for Children--Third Edition. Results indicate changes in the correlation with Woodcock-Johnson--Revised Tests of Achievement…

The practice of cognitive referencing to determine the presence of a specific language impairment (SLI) and eligibility for services is questioned by a study which compared the variability of the IQ scores of children with specific language impairment over time. The study found high IQ variability, suggesting that IQs reflect current abilities…
