Notifications & Family Decision Deadline

After the admission checklist has been completed, apps have been processed, and assessment results have been gathered, the Admission Committee will mail notifications on March 20, 2019 and post them online via admission portals on March 21, 2019. Families will have until 10 a.m. on March 28 to accept or deny admission offers.

Tuition determinations will be available online on March 21. If you need to discuss your tuition offer between March 21 and March 28, please contact Kara Diaz, Associate Director of Admission and Indexed Tuition, directly.


Traditional entry points for admission are kindergarten and sixth grade. Admission to all other grades is based upon attrition, and therefore difficult to predict if and when spaces may become available. We encourage you to apply if you feel MCDS would be a good fit for your child and family; should space become available we admit students from the current applicant pool.

  • Kindergarten Applicants

Children who are not age five by August 1 in the year they would enroll are not encouraged to apply; however there is not an absolute cut-off date. We have a developmental program that is appropriate for a range of children and waiting an extra year is not necessarily an automatic benefit.

  • Sixth Grade Applicants

As students move from fifth to sixth grade, the program shifts from self-contained classrooms to a departmental structure and grade-level advisor groups. This format allows us to admit approximately twenty new students, expanding the size of the grade which broadens the social dynamic of the class.

  • We do not accept applications to eighth grade.
