Background: Dyslexia is a specific reading disability characterized by word recognition difficulties that can qualify a student for special education services under the "Individuals with Disabilities Education Act" (IDEA; 2004; Yudin, 2015). As of 2024, 49 US states have legislation defining dyslexia and enumerating for schools…

After considering the relationships between (a) reading fluency and reading rate and (b) reading rate and sight vocabulary, this study addressed a very practical question. Can a cut score on a sight vocabulary task (1-min) predict level of reading fluency 4+ months into the future? The prediction was tested at multiple times point across grades…

The current study was completed through a retrospective analysis of school records of elementary school students in the Northeast Region of the Philadelphia School District (PSD) who have participated in the Fast ForWord (FFW) Language program. The data requested from student records included: demographic information (e.g., gender, grade, age,…

In the present study we examined the processing demands of three reading comprehension tests, namely the Woodcock-Johnson Passage Comprehension (WJPC), a Curriculum-Based Measure test (CBM-Maze), and a Recall test, in the early elementary years. Our investigation was theoretically motivated by Perfetti's Verbal Efficiency Theory and examined the…

In a sample of 195 first graders selected for poor reading performance, the authors explored four cognitive predictors of later reading comprehension and reading disability (RD) status. In fall of first grade, the authors measured the children's phonological processing, rapid automatized naming (RAN), oral language comprehension, and nonverbal…

A significant body of research exists on the development of early literacy skills and their relationship to the development of literacy as a whole. Phonological awareness, orthographic processing, rapid automatized naming, phonological memory, and receptive vocabulary have all been shown to be predictive of early reading outcome measures. What is…

Data analysis of 134 twin pairs from the Colorado Reading Project found that approximately 40 percent of the deficit observed in disabled readers is because of genetic factors, 35 percent because of environmental influences shared by twin pairs, and 25 percent because of environmental factors unique to the individual and/or error variance.…

This study investigated the relative importance of semantic, grammatical, phonological, and rapid naming abilities in predicting word identification skills in 200 children (grades 1-6) using correlation, factor analysis, multiple regression, and predictive outcome analysis techniques. Composite measures of these abilities correlated significantly…

The Minnesota Child Development Inventory (MCDI) was used to describe the developmental status of 59 children before the start of kindergarten. A number of variables from the MCDI were highly correlated with this continuum of difficulty in mastering reading, with parental report of the child's general development and knowledge of letters and…

This study, involving 54 first-grade children, found that correlations between decoding and phonological awareness were generally much higher than correlations obtained for measures of decoding and verbal and nonverbal intelligence. Several phonological awareness tasks identified good and poor decoders, with approximately 80-90% accuracy. (DB)

The study was designed to determine the best combination of tests or subtests in a research battery which, when administered to beginning first grade students (N=1,052), would enable the most efficient prediction of reading achievement. (Author/SBH)

The relationship between reading ability and recognition of four kinds of perceptual stimuli for purposes of reading disability diagnosis was investigated. The sample consisted of 84 male grade-3 pupils who were matched on intellectual ability but who differed in reading proficiency. Three groups, based on a 6-month discrepancy either above or…

The prereading and reading performance of 370 predominantly Hispanic, bilingual school children was followed for 6 years. A 5-test Screening Index misclassified many failing readers but accurately identified children who eventually read well. Predictor tests administered at beginning of first grade showed significant correlations with reading at…

This study examined the development of phonological and reading skills in 171 students from the beginning of first grade (Time 1) to the end of second grade (Time 4). The study found that reader group membership (nondisabled, reading disabled, or poor reading) at Time 4 could be very accurately predicted from students' Time 1 scores. (Author/DB)

This study examined possible early predictors of reading problems in at-risk children (ages 53 to 77 months). Results indicated that early measures of language awareness are good predictors of later reading performance but that different measures are good predictors for different children. (Author/DB)
