Tilden Middle School was originally built in 1967, was closed in 1986 and reopened in 1991. When the school reopened in 1991, facility improvements were done, but not a full modernization. Scheduling of this modernization is consistent with the MCPS long-range plans to renew aging facilities on a rational and periodic basis. The modernization will include an addition to this facility due to projected enrollment growth. Due to fiscal constraints, the middle school modernization program was delayed two years in the adopted FY 2013-2018 CIP. While planning funds remain on schedule, due to fiscal constraints, construction funds for this project were delayed one year in the approved FY2015-2020 CIP. The Board of Education's requested FY2015-2020 Amended CIP reinstated the construction schedule previously requested by the Board. Due to fiscal constraints, the County Council did not approve the Board's request. An FY 2016 appropriation was approved for planning funds. An FY 2019 appropriation will be requested for construction funds. The Board of Education in May 2015 approved the collation of Tilden MS with the Rock Terrace School. An FY 2019 appropriation will be requested for construction funds. This revitalization/expansion project is now scheduled to be completed by August 2020. An FY 2018 appropriation was approved to accelerate the site work for this project. An FY 2019 appropriation was approved for construction funds. This project is scheduled to be completed September 2020. An FY 2022 supplemental appropriation and transfer in the amount of $500,000 was approved from this project to the Charles W. Woodward HS Reopening project.
