This report highlights the Massachusetts Department of Elementary and Secondary Education's 2015-2016 achievements and continuing efforts made toward maintaining a record of meeting requirements under Individuals with Disabilities Education Act (IDEA), reorganizing their system of student and family supports, and improving outcomes for students with disabilities. In 2015, the Department experienced a significant reduction in staff, in large part due to an early retirement incentive program for staff and the end of their federal "Race to the Top" funding. The Department then launched a new initiative with the assistance of Parthenon-EY, a strategic consulting firm, to take stock of its organizational structure and identify changes that could be made to enhance coordination and planning while helping its staff and leadership work more efficiently and effectively. Parthenon-EY's recommendations, submitted to the Board of Elementary and Secondary Education in March 2016, focused on integrating and aligning work across the agency. In June 2016, the U.S. Office of Special Education Programs (OSEP) notified the Massachusetts Department of Elementary and Secondary Education ("the Department") that, for the third year in a row, Massachusetts met the requirements of IDEA.
