REL Mid-Atlantic supported the Office for Leadership Development and School Improvement at the Maryland State Department of Education (MSDE) in identifying and sharing research and practices for high school turnaround. MSDE identified 21 high schools as Comprehensive Support and Improvement (CSI) schools under its Every Student Succeeds Act accountability system because of low graduation rates. MSDE found there was a gap in resources, information, knowledge, and experience for staff in turning around high schools. REL Mid-Atlantic staff developed and delivered a two-session virtual workshop to the leaders of the 21 CSI high schools and the district and state staff who support them.
