Sligo Creek Elementary School and Silver Spring International Middle School (SSIMS) share a single campus and building, the former Montgomery Blair High School. The closure of SSIMS in July 2030 and the conversion of both SSIMS and Sligo Creek ES into holding schools has been proposed. This proposal is currently under consideration by the Board of Education, with action scheduled in 2026.

A site selection process will be initiated in Spring 2026, and the Board will request an FY 2027 appropriation to begin planning for a replacement school on a separate site, with anticipated completion in August 2029. If the Board elects to maintain the existing configuration of the two schools, no Capital Improvements Program (CIP) project for Sligo Creek ES will be requested.
