All programs run for the academic year beginning in late August. We also have a summer program which is put out in January for the following Summer. Summer programs are for enrolled children only. School classes are held Monday through Friday. Classes for children participating with their caregiver are currently held in the afternoons as they are taught by our wonderful 0-3 trained guides who are in class in the mornings.

Montessori Parenting Center Classes:

Classes for children participating with their caregiver are held in 5 or 6 week sessions. We are so excited to welcome people back to campus! These classes have been on hold during the Pandemic, so please be patient as we cautiously bring the first class back. We will follow with more offerings soon.

Please register for the Infant Parent Class below or call or email for more information.

Infant-Parent Classes (Infants from 6 weeks to "walking well" (able to carry objects) and a parent or other special adult)
We are very excited to be able to welcome younger siblings and families from the wider community back to our adult participation classes. We brought back our infant-parent series this summer and now have opened the first 2022-2023 Infant-Parent Series. It begins on September 14, 2022. Additional six week sessions begin October 26, January 18, March 1, and April 26. Times and dates will be adjusted based on feedback. Registration for the later sessions and other classes will be posted in late August and September.

The Infant-Parent class is a great way to get to know Montessori for the young child. Since the class is currently taught by our experienced Young Children's Community teachers, it is only available in the afternoons. We realize this is not ideal for naps. Feel free to use the registration form to give us feedback. We will take this into account for subsequent classes or if we add a second class.

Walking Child - Parent Classes (Young children from "walking well" to 3 years old and a parent or other special adult)
     This class replicates what happens in our Young Children's Community and is a great introduction to the class for our new students as well as any children of families interested in how to set up a home Montessori environment at home. Please click here for more information. We are working on new space for this class. Our registration will be posted on August 26th.
