The purpose of this study was to document within-year fidelity growth during installation and initial implementation of School-Wide Positive Behavioral Interventions and Supports (SWPBIS). Participants included school teams from schools throughout the United States that were in years 1 to 4 of SWPBIS implementation and routinely evaluated their…

The current study explored the extent to which a common measure of perceived implementation of critical features of Positive Behavioral Interventions and Supports (PBIS) predicted fidelity of implementation 3 years later. Respondents included school personnel from 261 schools across the United States implementing PBIS. School teams completed the…

This article draws on previously employed methods for conducting fidelity studies and applies them to an evaluation of an unprescribed intervention. We document the process of assessing the fidelity of implementation of the Math Recovery first-grade tutoring program, an unprescribed, diagnostic intervention. We describe how we drew on recent…

District implementation of the response to intervention (RTI) model has occurred at a surprising rate. It appears that implementation of RTI has occurred rapidly and is being implemented with all students. Rapid implementation of RTI is occurring alongside continued controversy over the model and its intended uses. Although significant research…

Large scale longitudinal research (Morgan, Farkas, & Wu, 2009) and a meta-analysis (Duncan et al., 2007) have found that early mathematics achievement is a strong predictor of later mathematics achievement. In fact, end of Kindergarten and end of grade 1 mathematics achievement on ECLS-K and similar mathematics proficiency measures tends to be…

Multilevel modeling techniques facilitated examination of relationships between fidelity indicators and outcomes associated with a summer literacy intervention. Three-level growth models were specified to capture the extent to which students experienced instruction and to demonstrate the ways in which dosage-response relationships manifest in…

More than a decade has passed since the National Research Council described the common elements of effective educational programs for young children with autism. Since that time, few studies have attempted to understand the mechanisms of change and factors affecting the effectiveness of research supported interventions implemented in community…
