The School Implementation Scale is a newly developed online survey designed to capture the personal adoption and level of individual implementation of school staff. The survey is designed to be deployed school-wide (all staff) as a way to measure levels of implementation over time. Presentation Abstract: Models of Response to Intervention (RTI) have been widely developed and implemented, and have recently expanded to include integrated academic/behavior RTI models. With so many RTI models incorporating their own process and evaluation measures, many schools find implementation of both academic and behavior models to be overwhelming. It is necessary to develop fidelity of implementation tools that reliably measure implementation across academic and behavior RTI models. In this presentation, we will report current research on RTI implementation measures and describe the School Implementation Scale, a measure successfully tested within three separate RTI models. This cost-effective, online measure shows high reliability across multiple models in elementary, middle, and high schools. Additionally, school personnel report that the results inform their action planning and data-based decision-making processes.#2012Conference #Instruments #Prek-12EducationalEvaluation #Cluster,Multi-SiteandMulti-LevelEval
