WHO:  Students entering grades 3-9 in Fall 2026. We also have a counselor-in-training (CIT) program for older high schoolers. Sometimes, we also admit very advanced rising 2nd graders (see our Evaluations Policy below). We reserve the right to deny admission to any rising 2nd grader for any reason.

​

WHAT:  Our summer program features a variety of fun, STEAM-related activities, including building challenges, number games, logic puzzles, and activities with our phenomenal guest instructors, many of whom are musicians, artists, architects, mathematicians, physicists, or engineers. Activities reflect the weekly theme (listed above).

​

COST:   $800 per week plus our $50 registration fee, with the option for an extended day until 5:15PM for an additional $200 per week per child. The registration fee is applied per student per summer once enrollment is confirmed, and is nonrefundable. Tuition costs are prorated for week 1, which runs a day shorter than the other weeks.

FINANCIAL AID: We offer need-based financial aid to low-income families, with priority given to families from Cambridge and Somerville, though everyone is welcome to apply. The $50 registration fee is still required of all families on financial aid; the fee will be refunded after the Summer Program ends. If a student on financial aid fails to attend during their enrolled week(s), the registration fee will not be refunded.

​

EVALUATIONS POLICY:  If your child is a rising 2nd grader, they must first undergo an evaluation before they can be admitted to our summer program. To schedule your evaluation, simply fill out our application and wait for a CMC staff member to contact you. 

​

SUMMER REFUND POLICY:   The one-time $50 registration fee is nonrefundable and is applied once per child, per Summer. Full Summer tuition refunds will be made if a family withdraws before May 1st. Withdrawals after May 1st will NOT receive a refund. (Families on financial aid will receive the $50 fee after the program's completion, or if they withdraw before May 1st).
