Response to intervention (RTI) can be both a system for providing early interventions to struggling students and a special education diagnostic tool for evaluating and identifying students with specific learning disabilities. Contributing to the very limited literature on state-level approaches, this report developed by the U.S. Department of Education Institute of Education Sciences describes how nine states define and support RTI at the state level, based on data collected between June and August 2008.
