Response to intervention (RTI) is a valuable framework for providing effective and equitable educational opportunities to all students; however, recent research indicates that RTI programs are not achieving their potential for promoting student learning. As schools develop, implement, and sustain RTI systems, they would benefit from the addition…

Assessing implementation allows for a better understanding of an intervention's effects and the mechanisms that influence its impact. Two main areas of implementation are: (1) the quality with which an intervention is delivered; and (2) instructors' adherence to the programmed intervention. The current study used data from a kindergarten…

Treatment fidelity refers to the extent to which an intervention is implemented as planned. If researchers do not assess and report treatment fidelity, or if treatment fidelity is shown to be low, findings from intervention studies are difficult to interpret, because the intervention may not have been implemented as planned. In this article, our…

The purpose of this study was to examine the role descriptive factors played in the perceptions of response to intervention (RTI) implementation success, challenges, and self-efficacy in a large Midwestern school district. District staff were surveyed as part of an evaluation of RTI implementation. Factors analyzed included teacher descriptive…

Multi-tiered Systems of Support (MTSS) frameworks are designed to directly support students with, and at risk for, disabilities by providing timely, aligned, and coordinated supports, with the goal of preventing or ameliorating the effects of early risk. Yet developing and implementing MTSS in beginning reading is a complex process. Many schools…

This paper presents the systems-level changes that were adopted by a school in Mumbai, India, to implement Tier 2 reading interventions. We specifically report on three areas at the micro level of change: universal screening for proactive support, systematic intervention for strategic support, and team collaboration for coordinated support; and…

We examined the effectiveness of a researcher-provided reading intervention with 484 fourth graders with significant reading difficulties. Students were randomly assigned to one year of intervention, two years of intervention, or a business-as-usual comparison condition (BAU). Students assigned to two years of intervention demonstrated…

This study was designed to determine how special education teachers (SETs) in Saudi Arabia perceive their self-efficacy in implementing social-emotional learning (SEL) practices to support students with learning disabilities (LD). The data were collected by surveying 109 SETs of students with LD who teach at elementary and middle schools in…

This article is about a school-district-initiated partnership with university faculty and their effort to implement a mathematics multi-tiered system of support (MTSS). In addition to reporting research about MTSS implementation, we describe how this district translated research into practice. We also share the perceptions of key stakeholders…

The purpose of the present article is to report on a large-scale investigation of six school districts' implementation of an initiative aimed at reducing dropout rates by improving reading achievement in the middle grades. Data for the Middle School Intervention Project (MSIP) were collected in 25 middle schools across the state of Oregon. We…

Promising findings from controlled research studies often fail to be transferred to and implemented in schools successfully. This problem is particularly apparent when considering implementation of evidence-based practices related to complex systems such as response to intervention (RTI) and other multitiered intervention frameworks in…

This study sought to provide educational researchers, policy-makers, and professionals with quantitative data on the status of RTI implementation, as well as on which leadership behaviors have been associated with successful implementation. School psychologists and other RTI professionals rated their schools on RTI implementation using the RTI…

Response to intervention (RTI) is advocated in elementary school as a system-wide, multitiered model of academic and behavioral interventions. Middle schools have begun adopting RTI models based on these existing elementary models. This investigation into current middle school RTI practices describes technical aspects as well as some of cultural…

Response to Intervention (RtI) is being implemented as a new initiative in PK-12 schools with increasing frequency. However, the model must be sustained at the school level, which is potentially difficult due to a number of challenges brought about by systems change. This article applied the Stokes and Baer (1977) framework for programming for…

In this review, we explore the extent to which researchers evaluating the efficacy of Tier 2 elementary reading interventions within the framework of Response to Intervention reported on fidelity of implementation and alignment of instruction between tiers. A literature search identified 22 empirical studies from which conclusions were drawn.…
