Cabin John Middle School

The MCPS 2024-2025 Change of School Assignment (COSA) transfer season opens on Monday, Feb. 3, 2025 and ends on Tuesday, April 1, 2025. The COSA process allows families to submit a request for their children to transfer out of their assigned home school.

Important changes for the upcoming COSA transfer process:
· Requests submitted after April 1, 2025, will not be considered unless there was a recent move or an emergency event that could not have been foreseen prior to April 1st.
· All COSA requests will now be submitted online through ParentVue in Synergy. Parents who need support on how to use ParentVue to complete an online COSA request will be encouraged to reach out to the Counseling Secretary & Registrar at their child’s assigned school.
· Detailed information related to the COSA process can be found in the 2025-2026 COSA information booklet, which will be available at the end of January. Hard copies will be available at Cabin John at the end of January.

If you have any questions please contact Mrs. Hardy, Counseling Secretary & Registrar  in the Counseling Office at (240) 406-1560.
