When a sibling attends a magnet, language immersion, or other application program at the elementary level, a COSA may be approved to the regular school program for other siblings on a case-by-case basis. Such approval requires consideration of available classroom space, grade-level enrollment, staffing allocations, or other factors that impact the schools involved.
These Students Do Not have to Submit a COSA If Requesting Another School Within Their Consortium:
Please Note: By accepting a COSA, the parent or guardian must provide transportation.
Parents and Guardians can now submit a Change of School Assignment (COSA) Request for the 2025-2026 school year in ParentVUE.

Schools Over Capacity Will No Longer Accept COSA Requests, After July 1
MCPS is committed to supporting schools that are overenrolled. As a result, beginning on July 1, 2025, schools whose enrollment is 10 percent or more over their identified building capacity will be closed to Change of School Assignment (COSA) requests. Parents who believe they have a unique hardship may still complete a COSA request, but they will be asked to request a school that is not over capacity. Enrollment and building capacity will be reviewed monthly.
Students in Montgomery County are expected to attend the school within the established attendance area in which they reside (home school) or assigned in accordance with their Individualized Education Program (IEP). Students may apply for a COSA based on certain criteria.
According to Board of Education Policy JEE, Student Transfers, a consideration for approval or denial of a COSA includes, “school capacity, including grade level and cluster capacity, and other issues that implicate the ability of the school to admit new students.”
