In the U.S., many states have adopted Response to Intervention (RTI) or Multi-tiered Systems of Supports to provide early intervention. However, there is considerable variability in how states and schools implement RTI. Teachers are responsible for using student data from RTI to inform instructional decisions for students with or at risk for…

In the USA, many states have adopted response to intervention or multi-tiered systems of supports to provide early intervention. However, there is considerable variability in how states and schools implement RTI. Teachers are responsible for using student data from RTI to inform instructional decisions for students with or at risk for dyslexia, so…

Successful implementation of intervention strategies for students having difficulties with reading is highly dependent on teachers' knowledge. Curricula alone do not teach; skilled teachers know how to prioritize learning objectives. For students who are struggling, or who have reading disabilities, including dyslexia, it is vital that teachers…

This study examined and quantified the maintenance of reading comprehension effects from a 4th-grade intervention for students with reading difficulties across the summer into the fall of 5th grade. We randomly assigned 4th-grade students with reading comprehension difficulties to a multicomponent reading intervention (Passport) or to typical…

This study examined and quantified the maintenance of reading comprehension effects from a fourth grade intervention for students with reading difficulties across the summer into the fall of fifth grade. Fourth grade students with reading comprehension difficulties were randomly assigned to a multi-component reading intervention (Passport) or to…

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…

For many students at risk of reading difficulties, effective, early reading instruction can improve reading outcomes and set them on a positive reading trajectory. Thus, response-to-intervention models include a focus on a student's Tier I reading instruction as one element for preventing reading difficulties and identifying students with a…

The present study used a randomized control trial to examine the effects of a widely-used multi-component Tier 2 type intervention, Passport to Literacy, on the reading ability of 221 fourth graders who initially scored at or below the 30th percentile in reading comprehension. Intervention was provided by research staff to groups of 4-7 students…

Purpose: The relations of phonological, orthographic, and morphological awareness and vocabulary to word reading and spelling were examined for 304 first-grade children who were receiving differentiated instruction in a Response to Intervention (RtI) model of instruction. Method: First-grade children were assessed on their phonological,…

This randomized control study compares the efficacy of two response-to-intervention (RTI) models: (1) Dynamic RTI, which immediately refers grade 1 students with the weakest skills to the most intensive intervention supports (Tier 2 or Tier 3); and (2) Typical RTI, which starts all students in Tier 1 and after 8 weeks, decides whether students who…

Two primary purposes guided this quasi-experimental within-teacher study: (a) to examine changes from baseline through 2 years of professional development (Individualizing Student Instruction) in kindergarten teachers' differentiation of Tier 1 literacy instruction; and (b) to examine changes in reading and vocabulary of 3 cohorts of the teachers'…

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…

This randomized controlled experiment compared the efficacy of two response-to-intervention (RTI) models--typical RTI and dynamic RTI--and included 34 first-grade classrooms (n = 522 students) across 10 socioeconomically and culturally diverse schools. Typical RTI was designed to follow the two-stage RTI decision rules that wait to assess response…

The purpose of this study was to use a mixed methods approach to learn about inadequate response to a year-long multi-tier response to intervention (RTI) model that allowed first-grade students to move up and down tiers. Participants were 156 students who received supplemental intervention services during a larger multi-tier RTI study involving…

We examined growth trajectories of writing and the relation of children's socioeconomic 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…
