The recent special report, "Indiana's Vision of Response to Intervention" issued by the Center for Evaluation & Education Policy (CEEP) was the first of a three-part series aimed to build a fundamental understanding of a Response-to-Intervention (RTI) framework in Indiana's schools to aid in the prevention and intervention of both academic and behavioral problems for all students. The report also discussed the impetus for implementation of RTI, as well as what the state of Indiana is currently doing to respond to and guide schools through this new initiative. Specifically, Indiana's Department of Education (IDOE) has developed a framework of RTI that addresses six core components on which to focus: (1) evidence-based curriculum, instruction, intervention and extension; (2) assessment and progress monitoring; (3) data-based decision making; (4) leadership; (5) family, school, and community partnerships; and (6) cultural responsivity. According to a statewide RTI survey of Indiana educators administered by CEEP in January of 2009, 85.2% of respondents indicated that their school is either conceptualizing their RTI framework or in the initial stage of implementation. Thus, the current report examines in greater depth the first three core components of the RTI framework to support schools in their implementation and understanding of: evidence-based core curriculum, instruction, intervention and extension; assessment and progress monitoring; and data-based decision making.
