The U.S. Department of Education's Office of Special Education Programs (OSEP) implemented Results Driven Accountability (RDA) in 2014 to help improve the educational outcomes of students with disabilities. As part of RDA, states were required to develop a State Systemic Improvement Plan (SSIP), which is a comprehensive, multi-year plan designed to improve outcomes for children with disabilities, and to commit to a State-Identified Measurable Result (SIMR) focused on student outcomes. Beginning in 2015, states incorporated the SSIP into their Annual Performance Reports (APR) that they submit to OSEP. Many states include local assessments in their SSIP, often as a measure of progress toward their SIMR. The purpose of this Brief is to outline key strategies for the collection, analysis, and use of local assessment data to monitor progress toward the SIMR. It provides information and suggestions for state education agencies and technical assistance providers who work with local education agencies (LEAs). It highlights six strategies, and then identifies several questions that states may want to consider if they choose to use local assessment data to measure progress toward their SIMRs. It is hoped that these strategies will support improved decision making at the state and local levels.
