Purpose: Researchers have developed a constellation model of decodingrelated reading disabilities (RD) to improve the RD risk determination. The model's hallmark is its inclusion of various RD indicators to determine RD risk. Classification methods such as logistic regression (LR) might be one way to determine RD risk within the constellation…

The present study examined the reading comprehension and receptive vocabulary skills of children with poor reading comprehension despite adequate decoding using a regression-based matching technique. Participants included five cohorts of children who were identified as typical readers (N = 70,493 - 75,553) or as children with specific reading…

Purpose: Children who do not develop early literacy skills, especially phonological awareness (PA) and alphabet knowledge, prior to kindergarten are at risk for reading difficulties. We investigated a supplemental curriculum with children demonstrating delays in these skills.Method: A cluster randomized design with 104 preschool-age children in 39…

There is an extensive body of research establishing measures of oral reading fluency as valid and reliable predictors of important reading outcomes and performance on high stakes tests (Good, Simmons, & Kame'enui, 2001). The present study was conducted to determine whether these findings also apply to the Florida Comprehensive Assessment Test…

Recent research suggests that the etiology of reading achievement can differ across environmental contexts. In the US, schools are commonly assigned grades (e.g. "A," "B") often interpreted to indicate school quality. This study explored differences in the etiology of early literacy skills for students based on these school…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

The present study explores the longitudinal development between Grade 3 word level reading skills and higher level semantic skills to Grade 10 reading comprehension for 3,157 students. In particular, this work focused on how the developmental relations varied for subsamples of students who are English learners (EL; N = 308), students identified as…

Little is known about the early educational performance of children in migrant farmworker families. The authors examined the school readiness and early school success of 289 four-year-old preschool children of migrant families attending Redlands Christian Migrant Association centers. Children's school readiness was assessed and public school…

Children's emergent literacy skills are highly predictive of later reading abilities. To determine which children have weaker emergent literacy skills and are in need of intervention, it is necessary to assess emergent literacy skills accurately and reliably. In this study, 1,351 children were administered the "Revised Get Ready to…

This study examined the predictive validity of formative assessments embedded in a Tier 2 intervention curriculum for kindergarten students identified as at risk for reading difficulty. We examined when (i.e., months during the school year) measures could predict reading outcomes gathered at the end of kindergarten and whether the predictive…

The present study examined the amount, type, and quality of Tier 1 and supplemental reading instruction provided to fourth-grade struggling readers and whether specific elements of instruction predicted growth in reading skills. 110 students identified as having reading difficulty, receiving school-based reading instruction in 22 classrooms…

The present study examined the amount, type, and quality of Tier 1 and supplemental reading instruction provided to 4th-grade struggling readers and whether specific elements of instruction predicted growth in reading skills. In all, 110 students identified as having reading difficulty who were receiving school-based reading instruction in 22…

This study examined the predictive validity and classification accuracy of individual- and group-administered screening measures relative to student performance on a year-end state reading assessment in two states. A sample of 321 students was assessed in the areas of word-level and text fluency, as well as reading comprehension in the fall of…

A sample of 321 students were assessed in the areas of word-level and text fluency, as well as reading comprehension in the fall of…

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…
