Registration Information

The following is information and guidelines for school registration.

Please note that CSS strongly discourages children under the age of 10 from registering for more than one class, and typically two classes is the maximum number that children should take.

Registration for classes for summer 2023 is now open.  Tuition for each 3-week course is $340, and each 6-week course is $680.  A non-refundable $35 fee is due at the time of registration.

COVID Policy

All CSS students, faculty & staff are required to be up-to-date on their COVID vaccinations, which means they have received the bivalent booster. Written requests for medical and religious exemptions will be considered.


The Children’s School of Science is committed to making our classes available to all children regardless of a family’s ability to afford the fee.  If you believe your child would benefit from taking a class with CSS, but feel that costs are a barrier, please use the “Apply for Financial Aid” button during registration, or send an email request.

Volunteer service

CSS is run by volunteers. All parents are asked to volunteer whenever possible, but at the minimum, all parents of enrolled children must provide transportation for at least one field trip, or work at the CSS front desk for two class periods per three-week period enrolled. For a six-week course, it is expected that a parent will drive for two field trips or work at the desk for four class periods per child. Please note, additional children are not permitted to accompany parents during volunteer duties.
