This toolkit provides an overview of the public reporting requirements in IDEA Section 616. SEAs and Part C lead agencies (LAs) must report on the annual performance of their LEAs and early childhood local programs on the targets in the SPP. The toolkit includes the Section 616 legislation and provides information about the why, what, who, and how of state reporting of local performance data. The user-friendly, web-based toolkit allows Part B state directors, 619 coordinators, Part C coordinators, data managers, and other internal and external stakeholders to better understand the scope of what states must report annually about local programs. The resource goes beyond the basic requirements for reporting and offers suggestions for ways to present local performance information in easy-to-understand formats for various audiences.
