In fall 2023, MMS will become MMS@Calhoun—a Montessori program for preschool-grade 3—when we merge with The Calhoun School. Tuition for MMS@Calhoun will match tuition for The Calhoun School’s lower school. MMS@Calhoun students will also apply for tuition assistance through Calhoun. You can learn more about Calhoun tuition and financial aid here.

If you are applying for the current school year (2022-23), please contact and we will provide you with information about tuition for the current year.
