Because several studies have investigated student outcomes in schools implementing Response to Intervention (RtI), relatively little research has investigated the impact of implementation on students' long-term achievement outcomes (i.e., several years after exposure). The purpose of this study was to describe one elementary school's RtI…

The purpose of this study was to compare the long-term effects of 2 first-grade Response to Intervention (RTI) models (Dynamic and Typical RTI) on the reading performance of students in second and third grade. Participants included 419 first-grade students (352 in second grade and 278 in third grade after attrition). Students were classified based…

We explored the usefulness of first and second grade reading measures and responsiveness criteria collected within a response-to-intervention (RtI) framework for predicting reading disability (RD) in third grade. We used existing data from 387 linguistically diverse students who had participated in a longitudinal RtI study. Model-based predictors…

Early identification of students who are at-risk for reading difficulties (RD) is critical for successful and effective RTI implementation. A large group of students were followed for three years (grades 2 to 4) to investigate transition patterns of risk-categories across three years. Results indicated that although students identified at…

The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…

This 4-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 1-4. We compared identification rates for learning disabilities (LD) and student characteristics of 381 students the year prior to…

Identifying proper measure to monitor students' growth and understanding characteristics of growth patterns between different achieving groups are critical issues in terms of screening students at risk. To deal with this, we explored relationships of slopes and intercepts between word identification (ID) and passage reading fluency (reading aloud)…

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…

This research investigated the immediate and long-term effects of a Tier 2 intervention for beginning readers identified as having a high probability of reading failure using a randomized control trial. First-grade participants (n = 123) were randomly assigned either to a 25-session intervention targeting key reading components, including…

Great progress has been made in learning how to provide more responsive instructional and behavioral supports to students through efforts in Response to Intervention and Positive Behavior and Intervention Supports. This article presents information and data on a longitudinal study designed to accelerate first graders at-risk for reading…

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…

Reading is the most valuable skill children must master early in schooling. Unfortunately, many students struggle to read and may be identified as having a Reading Disability (RD). In this dissertation, I explored the usefulness of the Response-to-Intervention (RtI) framework for identifying children with RD by examining the use of 1st and 2nd…
