This four-year longitudinal research was designed to study special education determinations of students who participated in Tier 2 intervention in a Response to Intervention (RtI) model focused on reading across Grades 1 through 4. We compared identification rates for learning disabilities and student characteristics of 381 students the year prior…

We explored the usefulness of 1st and 2nd grade reading measures and responsiveness criteria collected within a Response-to-Intervention (RtI) framework for predicting Reading Disability (RD) in 3rd grade. We used existing data from 387 linguistically diverse students who had participated in a longitudinal RtI study. Model-based predictors of RD…

We examined growth trajectories of writing and the relation of children's socio-economic status, and language and/or speech impairment to the growth trajectories. First grade children (N = 304) were assessed on their written composition in the fall, winter, and spring, and their vocabulary and literacy skills in the fall. Children's SES had a…

In a randomized controlled trial, 205 students were followed from grades 1 to 3 with a focus on changes in their writing trajectories following an evidence-based intervention during the spring of second grade. Students were identified as being at-risk (n=138), and then randomized into treatment (n=68) versus business-as-usual conditions (n=70). A…

In this study, we tested the outcomes of access to a Response to Intervention (RtI) model in kindergarten or in first grade on end-of-Grade-2 reading achievement and placement in special education. Across five schools, 214 students who began having access to Tier 2 intervention in kindergarten or first grade were compared in Grades 1 and 2 with…
