Understanding how to intensify an intervention is critical to implementing response-to-intervention (RtI), a tiered, problem-solving framework to deliver evidence-based interventions per student needs. Research and practice guidelines provide conflicting recommendations for delivering math interventions (i.e., treatment intensity) within RtI. The…

Some Swedish schools do not identify and support students with reading difficulties efficiently enough during the first years at school. A longitudinal design was used to examine a multitiered RtI-model for identifying and supporting students at risk of reading difficulties in a Swedish school context. The results demonstrated that the RtI-model…

This study examines the impacts of two AmeriCorps programs, Minnesota Reading Corps and Wisconsin Reading Corps, where AmeriCorps volunteers provide literacy tutoring to at-risk kindergarten through third-grade (K-3) students utilizing a response-to-intervention framework. This evaluation replicates a prior randomized controlled trial evaluation…

The main objective of this study was to evaluate the efficacy of a Tier 2 intervention within the context of the Response to Intervention (RtI) model implemented by Spanish first- to second-grade primary school teachers to improve at-risk students' transcription skills. Teachers were instructed in the administration of a writing curriculum-based…

Much is known about the role of vocabulary in reading and the instructional procedures that improve vocabulary. Relatively less is known about feasible approaches to implement vocabulary interventions for struggling readers within tiered frameworks. The current study randomly assigned at-risk kindergarten and first-grade students to a vocabulary…

The implementation of Response to Intervention (RTI) has increased over the years and provided students with the support needed to close the learning gap and succeed in school. The purpose of this study was to evaluate the perceptions of the effectiveness of the RTI framework in a rural school district in Tennessee. The study included kindergarten…

We present quantitative results from the pilot-year of a large scale Swedish educational project in reading development called LegiLexi, inspired by research within the response to intervention and formative assessment traditions. The vision of the project is that every pupil should reach adequate reading skills at the end of grade 3 in primary…

This study examined the role of initial skill in moderating intervention effects of a 50 lesson mathematics intervention program, ROOTS, for at risk kindergarten students focused on developing whole number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

Children with Developmental Language Disorder (DLD) commonly present with oral language weaknesses which disrupt the development of literacy and impede related academic progress. While there is evidence to support the delivery of manualised Tier 2 interventions with this population, little is known about the effects of Tier 1 interventions. A…

This study examined the role of initial skill in moderating intervention effects of a 50-lesson mathematics intervention program, ROOTS, for at-risk kindergarten students focused on developing whole-number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

Response to intervention (RTI) is a comprehensive early detection and prevention strategy used to identify and support struggling students before they fall behind. An RTI model usually has three tiers or levels of support. Tier 1 is generally defined as classroom instruction provided to all students, tier 2 is typically a preventive intervention…

The authors examined whether Reading Rescue continues to be an effective literacy intervention and factors that impact its effectiveness. Data were collected on 143 first-grade students, tutored by 104 tutors at 38 schools. There was significant growth on all foundational skills (ps < 0.001) and significant change in proportion of students…

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…

Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a…

Many schools identified by states as needing improvement through their Elementary and Secondary Education Act waivers have selected Response to Intervention (RTI), a three-tiered instruction program sometimes referred to as tiered levels of instruction, as one of their main strategies for improving school performance and closing achievement gaps.…
