This study aims to classify subtypes of mathematics disability (MD) using a novel classification method, cognitive diagnostic models (CDMs), and examine whether domain-general skills, namely, linguistic, working memory, and spatial skills, were related to the identification of the subtypes. Participants were 454 children (246 boys; age: M ± SD =…

This article reports on a study designed to determine if the lowest achieving first-grade students who were identified by their school districts as at-risk for dyslexia can be distinguished from students who have initial reading and writing difficulties but did not present dyslexia characteristics. Thirty-six first-grade students from two…

Within the Canadian context, the two major learning disability classification systems are arguably the American Psychiatric Association's (APA) "Diagnostic and Statistical Manual of Mental Disorders" and the Learning Disabilities Association (LDAC) of Canada's "Official Definition of Learning Disabilities." Several of the more…

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…

As it has become a prominent feature in the identification of students with specific learning disabilities (SLD), response to intervention (RTI) has generated significant interest and, in some respects, controversy regarding assessment and attendant procedures. In the present study, the authors surveyed state directors of special education…

Students' self-determination plays a critical role in both in-school and post-school outcomes. This study examined the self-determination of English learners with disabilities in secondary school, based on a secondary analysis of the National Longitudinal Transition Study 2012 (NLTS 2012). The NLTS 2012 youth survey, conducted in English and…

Traditionally, students with learning disabilities (LD) have been identified using an aptitude--achievement discrepancy or response to intervention approach. As profiles of the cognitive deficits of discrepancy-defined students with LD have already been developed using these approaches, these deficits can in turn be used to identify LD using the…

The present study employed data simulation techniques to investigate the 1-year stability of alternative classification schemes for identifying children with reading disabilities. Classification schemes investigated include low performance, unexpected low performance, dual-discrepancy, and a rudimentary form of constellation model of reading…

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…

This study used a statewide longitudinal sample to examine mathematics achievement gaps and growth in students with and without disabilities and to examine the impact of different methods of determining disability group membership on achievement gaps and growth. When disability status was determined on the basis of special education placement each…

In a 3-year longitudinal study, 471 children were classified, based on their performances on arithmetic tests in first and second grade, as having persistent arithmetic disabilities (AD), persistent low achieving (LA), persistent typical achieving, inconsistent arithmetic disabilities (DF1), or inconsistent low achieving in arithmetic. Significant…

Some young children show signs that they may not be learning in an expected manner, even during the prekindergarten (PreK) years. These children may exhibit learning challenges in areas such as developing language, counting objects, hearing differences in letter sounds, paying attention during story time, or learning how to write. Teachers,…

A fundamental assumption in the identification of specific learning disabilities (SLD) has been that the presence of a severe discrepancy between ability and academic achievement is a valid marker for the presence of a SLD. This assumption is based on the notion that discrepant low achievers constitute a unique group of children who are different…

Objective: There is a dearth of cross-cultural research on hyperactivity. This article aims to quantify the prevalence of hyperactivity in schoolboys residing in an Arab/Islamic country, Oman. Method: 1,502 Omani schoolboys from eight randomly selected schools representing the urban population of Oman were screened for various indices of…

This issue focuses on practices that can help improve reading instruction and includes two announcements from Southwest Educational Development Laboratory (SEDL). It begins with a look at study groups, the practice of teachers getting together to focus on instructional practices and student learning. Stacey Joyner, a staff member of SEDL's Texas…
