This report has been provided to the Legislature on an annual basis since 2000 when the legislature amended the language of G.L. c. 71B to align Massachusetts special education terminology with the federal "Individuals with Disabilities Education Act" ("IDEA"). The Department is required to submit an annual report on compliance and performance to the Office of Special Education Programs (OSEP) each year on February 1. This annual state legislative report provides: (1) statewide longitudinal enrollment data on students with disabilities; (2) data on the percentage of students with disabilities by disability category, educational environment, and other special population status; (3) descriptions of programs, initiatives, improvement activities, and a brief discussion framing the most recent reports on special education in Massachusetts by Dr. Thomas Hehir and Associates, as well as the Education Development Center, Inc. (EDC); (4) an overview of improvement activities such as the Secondary Transition Conference, federally funded grants available to support targeted improvement activities throughout the Commonwealth, and the Transition Endorsement initiative; and (5) a financial summary of special education expenditures and a summary of the School-Based Medicaid program.
