Please note that the Tregaron Campus (Grades 6 to 12) is a 10 minute walk from the Cleveland Park Metro station (Red Line). Residents of the District of Columbia, who attend WIS, are eligible for the Kids Ride Free program to ride the Metrorail, Metrobus, and DC Circulator for free.

Any currently-enrolled WIS student or prospective student is required to live with that individual’s parent(s) or an official legal guardian. 

The School does not offer a homestay program. However, the School recognizes that, for various reasons, a family may need to create its own version of a homestay program that is neither structured nor overseen by the School. The School will permit certain exceptions to its no-homestay policy on a case-by-case basis. Contact the Director of Admissions and Financial Aid to petition an exception to the no-homestay policy.
