Summer Program

The Keystone Montessori School Summer Program is an extension of Keystone’s standard academic year.  We offer care for our Infants through Children’s House students. Students who attended the CH program during the school year are eligible to attend the CH Summer program. The Summer Program is staffed by Keystone Montessori teachers and trained assistants. The KMS Summer Program begins during staff work week, and continues until school resumes for returning students. The Summer Program runs Monday through Friday from 7:00 am-6:30 pm. Full and half days are available. Sign up for weeks, sessions or entire summer. Please call (978) 251-2929 for questions about this program.
