Considerable attention and legislation are currently focused on developmental dyslexia. A major challenge to these efforts is how to define and operationalize dyslexia. In this article, we argue that rather than defining dyslexia on the basis of an underlying condition, dyslexia is best viewed as a label for an unexpected reading disability. This…

The science of reading should be informed by an evolving evidence base built on the scientific method. Decades of basic research and randomized controlled trials of interventions and instructional routines have formed a substantial evidence base to guide best practices in reading instruction, reading intervention, and the early identification of…

Purpose: In this study, we examine how well kindergarten letter identification and phonological awareness predict 2nd grade word reading and dyslexia in children with developmental language disorder (DLD) and their age- and grade-matched peers with typical language (TL). Method: We employ (a) logistic regression to determine how letter…

Participants were administered multiple measures of phonological awareness, oral language, and rapid automatized naming at the beginning of kindergarten and multiple measures of word reading at the end of second grade. A structural equation model was fit to the data and latent scores were used to identify children with a deficit in phonological…

The simple view of reading proposes that reading comprehension is the product of word reading and language comprehension. In this study, we used the simple view framework to examine the early prediction of reading comprehension abilities. Using multiple measures for all constructs, we assessed word reading precursors (i.e., letter knowledge,…

Early and accurate identification of children at risk for reading disabilities (RD) is critical for the prevention of RD within a response to intervention framework. In this study, we investigated the use of universal screening and progress monitoring for the early identification of RD in kindergarten children. A total of 366 children were…

Screening for early reading problems is a critical step in early intervention and prevention of later reading difficulties. Evaluative frameworks for determining the utility of a screening process are presented in the literature but have not been applied to many screening measures currently in use in numerous schools across the nation. In this…

Multiple studies have shown that kindergarten measures of phonological awareness and alphabet knowledge are good predictors of reading achievement in the primary grades. However, less attention has been given to the early predictors of later reading achievement. This study used a modified best-subsets variable-selection technique to examine…

This longitudinal study used piece-wise growth curve analyses to examine growth patterns in oral reading fluency for 1,991 students with speech impairments (SI) or language impairments (LI) from first through third grade. The main finding of this study was that a diagnosis of SI or LI can have a detrimental and persistent effect on early reading…

Response to intervention (RTI) holds great promise for the early identification and prevention of reading disabilities. The success of RTI rests in part on the accuracy of universal screening tools used within this framework. Despite advancements, screening instruments designed to identify children at risk for reading disabilities continue to have…

Purpose: This study examined the reading achievement growth of children with language impairments (LI) across the school grades. The authors sought to determine whether children with LI demonstrate a delayed, deficit, or cumulative pattern of reading achievement growth when compared with children with typical language (TL). Method: A group of 225…

Reviews the language basis of reading disabilities and provides a checklist of language deficits frequently associated with reading disabilities. Areas assessed include: word retrieval, verbal memory, speech production, comprehension, expressive language, and speech sound awareness. The checklist is designed for early identification of reading…

The article reviews research on the language basis of reading disabilities and draws implications for early identification. The article considers language problems in reading-disabled children, follow-up studies of language-impaired children, and phonological processing and reading disabilities. Implications include the value of preschool…

Current research supporting the language basis of dyslexia is reviewed, suggesting that phonological processing deficits are at the core of dyslexia and less pronounced reading problems. The role of higher-level language functioning and phonological processing is considered in an expanded view of the language basis of reading disabilities.…

Fifty-six children with speech-language impairments were identified in kindergarten and followed in first and second grades. Subjects' performance on standardized measures of language ability in kindergarten was closely related to reading outcome, especially reading comprehension. Measures of phonological awareness and rapid automatized naming…
