This pre-registered systematic review and meta-analysis aimed to answer if K-2 students at risk (Population) for reading impairment benefited from a response to tier 2 reading intervention (Intervention) compared to teaching as usual, (Comparator), on word decoding outcomes (Outcome), based on randomized controlled trials (Study type). Eligibility…

Within a three-tiered intervention framework, such as School-Wide Positive Behavioral Interventions and Supports, Tier 2 interventions were initially conceived as employing a standard protocol across all at-risk students. Research and practice, however, suggests advantages to adapting interventions so they are tailored to individual student needs.…

To prevent academic failure and promote long-term success, response-to-intervention (RtI) is designed to systematically increase the intensity of delivering research-based interventions. Interventions within an RtI framework must not only be effective but also be implemented with treatment fidelity and delivered with the appropriate level of…

This meta-analysis systematically reviewed the most up-to-date literature to determine the effectiveness of reading interventions on measures of word and pseudoword reading, reading comprehension, and passage fluency, and to determine the role intervention and study variables play in moderating the impacts for students at risk for reading…

Purpose: Specific language impairment (SLI; see also developmental language disorder) and dyslexia are separate, yet frequently co-occurring disorders that confer risks to reading comprehension and academic achievement. Until recently, most studies of one disorder had little consideration of the other, and each disorder was addressed by different…

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…

This meta-analysis extends previous work on extensive Tier 3 type reading interventions (Wanzek & Vaughn, 2007; Wanzek et al., 2013) to Tier 2 type interventions by examining a non-overlapping set of studies addressing the effects of less extensive reading interventions for students with or at risk for reading difficulties in Grades K-3. We…

This meta-analysis extends previous work on extensive Tier 3 type reading interventions (Wanzek and Vaughn "School Psychology Review," "36", 541-561, 2007; Wanzek et al. "Review of Educational Research," "83", 163-195, 2013) to Tier 2 type interventions by examining a non-overlapping set of studies…

This article synthesizes reading intervention research studies intended for use with struggling or at-risk students to determine which studies adequately address population validity, particularly in regard to the diverse reading needs of English language learners. An extensive search of the professional literature between 2001 and 2010 yielded a…

Although Response to Intervention (RTI) has been generally studied in relation to student outcomes, the system itself requires further study, particularly for culturally and linguistically diverse (CLD) students. CLD students have consistently suffered inequities in the educational system, including over representation in high incidence disability…

Special education disproportionality for culturally and linguistically diverse (CLD) students persists as a controversial and intractable problem in our educational systems. Response to intervention (RtI) and culturally relevant pedagogy (CRP), both independently and collectively are considered to offer promise for mitigating conditions of…

The purpose of this review was to update previous reviews on factors related to students' responsiveness to early literacy intervention. The 14 studies in this synthesis used experimental designs, provided small-group or one-on-one reading interventions, and analyzed factors related to responsiveness to those interventions. Participants were…

Response to intervention (RTI) is a framework in which interventions are implemented mostly in general education classes to resolve academic difficulties and help to mitigate contextual variables (i.e., lack of instruction, socio economic status, cultural differences, etc.) as an explanation for academic failure. The implementation of…

This review provides an introduction to response to intervention (RTI), including how it is defined, reasons for its growing popularity, an introduction to an emerging body of research, a brief discussion of what it all means, and suggestions about directions for future research. [This was originally published as part of a larger study, "The…

Response to intervention (RTI) has actively been used for identifying reading difficulties and providing supplemental instructions for students with disabilities. Recent developments of RTI show that the method expands its applicability to other areas and populations. In particular, it is difficult to distinguish learning disability (LD) from…
