Program Payments

Each program session requires a non-refundable deposit at the time of registration. Balances for all programs are due by May 1. All deposits are non-refundable, and all payments are non-refundable after May 1.


Registration Information for Summer Studies Credit Courses

Summer Studies questions should be directed to the Director of Summer Studies, Tom Donley, at or 202-537-8173.

Please note the Summer Studies Application must be completed for Summer Studies credit courses (online registration is not available) in order to ensure that proper approval is received in advance. 

Students wishing to receive credit for a Summer Studies course must get prior approval from the school in which they are enrolled. The appropriate school official’s signature is required on the application form. For Sidwell Friends students, this is mandatory prior to submitting an application. For students from other schools, it is highly recommended that approval is received prior to submitting an application, to ensure that credit for the course will be received. In some cases, Sidwell Friends students may be given enrollment priority.

A six-week credit course meets three and a half hours daily and is the equivalent of a full year course, worth one credit. Any anticipated absence longer than two days must be cleared with the Director of Summer Studies prior to the start of classes. A student who misses more than two instructional days of class may not receive credit for the course. If a student will be unexpectedly absent, please call 202-537-8160 by 8:30am on the morning of the absence.

The school reserves the right to cancel any course or to make modifications to any course as required. Students affected will be notified immediately. 

Note for Sidwell Friends students: SFS students applying for credit courses must submit applications to the Sidwell Summer Office after receiving the appropriate signatures. Enrollment priority will go first to students who have extenuating circumstances. The remainder of the course roster will be filled based on the order in which applications are received. If enrollment in a given course reaches capacity, Sidwell Summer will maintain a waiting list for the course.

Early Risers/Camp ‘til Six Registration

Camp 'til Six and Early Risers are available for weekly registration on both the DC and Bethesda Campuses. Early Risers and Camp 'til Six weekly registration should be done in conjunction with camp program registration. Both are listed as options under each camp session, during registration.

Weekly registration must be completed no later than noon on Friday of the week prior to camp. Registration based on availability.


Registration Deadlines

Registration is on a first come, first registered basis for all programs, classes, and program workshops. Many programs fill early and, therefore, early registration is encouraged to ensure space in desired session.  If the program is not already full, the deadline for registering for Sidwell Summer programs is as follows:

For Explorer Programs (Explorer CAP, ExploreStar, Explorer Day Camp, Junior Explorers), the deadline for registration, as well as workshop changes, is 12:00pm on the Thursday before a session begins.

For all other programs, the deadline for registration (including Extended Day programs) is 12:00pm on the Friday before a session begins, if the program is not already full.

Registrations are not accepted after this deadline.


Waitlists for Programs

Once a session is filled, a waitlist for that session is begun through the online registration system. Click the “Register Now” link at the top of any page on the website and follow the prompts leading to the desired session. Select the "Waitlist" associated with the desired session and complete all requested information. No deposit or payment is required until a space is offered to a camper or student.

Should a space become available, Sidwell Summer will directly contact families on the waitlist to fill the space, in the order in which registrants were waitlisted. A family typically has 24 hours to accept the available space.
