This annual report describes the activities of the four Individuals with Disabilities Education Act (IDEA) Partnerships created by the Office of Special Education Programs to provide reliable information on IDEA. The Partnerships include: (1) the Associations of Service Providers Implementing IDEA Reforms in Education (ASPIIRE) Partnership; (2) the Families and Advocates Partnership for Education (FAPE) Partnership; (3) the IDEA Local Implementation by Local Administrators Partnership (ILIAD); and (4) the Policymaker Partnership (PMP). These four partnerships were expected to build a collaborative of organizations committed to implementing IDEA that, in turn, would support its constituents at the local and state levels in doing the same. A Partnerships Coordinating Committee has also been created to forge relationships across stakeholder groups. The report discusses the milestones the partnerships have reached in Year 4 in the areas of creating opportunities to learn together about IDEA, creating opportunities to form relationships, and creating opportunities to improve practice. Achievements of the partnerships include providing user friendly and reliable information about IDEA to all stakeholders, sponsoring the first national summit on IDEA, and creating the IDEA National Resource Cadre. Contact information for each of the partnerships is provided. (CR)
