Peer reviewed Peer reviewed
Direct linkDirect link
Miciak, Jeremy; Taylor, W. Pat; Stuebing, Karla K.; Fletcher, Jack M. – Journal of Psychoeducational Assessment, 2018
We investigated the classification accuracy of learning disability (LD) identification methods premised on the identification of an intraindividual pattern of processing strengths and weaknesses (PSW) method using multiple indicators for all latent constructs. Known LD status was derived from latent scores; values at the observed level identified…

Miciak, Jeremy; Taylor, W. Pat; Denton, Carolyn A.; Fletcher, Jack M. – School Psychology Quarterly, 2015
Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability of LD classification decisions of the concordance/discordance method (C/DM) across different psychoeducational assessment batteries. C/DM criteria were…

Miciak, Jeremy; Fletcher, Jack M.; Stuebing, Karla K.; Vaughn, Sharon; Tolar, Tammy D. – School Psychology Quarterly, 2014
Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability and validity of two proposed PSW methods: the concordance/discordance method (C/DM) and cross battery assessment (XBA) method. Cognitive assessment…

Intelligent Testing and the Discrepancy Model for Children with Learning Disabilities.
Peer reviewed Peer reviewed
Fletcher, Jack M.; Francis, David J.; Shaywitz, Sally E.; Lyon, G. Reid; Foorman, Barbara R.; Stuebing, Karla K.; Shaywitz, Bennett A. – Learning Disabilities Research and Practice, 1998
Reviews the historical basis and rationale for identifying children as learning disabled due to a discrepancy between scores on measures of intelligence and achievement. Discusses the validity of such classifications and the role of IQ testing in the designation of children as learning disabled for research and public policy. Alternative…

The Validity of Distinguishing Children with Language and Learning Disabilities According to Discrepancies with IQ: Introduction to the Special Series.
Peer reviewed Peer reviewed
Fletcher, Jack M. – Journal of Learning Disabilities, 1992
This article, which introduces six papers on the validity of distinguishing subgroups of children with language and learning disabilities based on discrepancies between academic attainment and intelligence test scores, comments on the papers' diversity in samples, measurement characteristics, and statistical approaches and outlines the studies'…

Fletcher, Jack M.; Coulter, W. Alan; Reschly, Daniel J.; Vaughn, Sharon – Annals of Dyslexia, 2004
Recent consensus reports concur in suggesting major changes in the federal regulatory approach to the identification of learning disabilities (LD). These reports recommend abandoning the IQ-discrepancy model and the use of IQ tests for identification, and also recommend incorporation of response to instruction (RTI) as one of the identification…
