Each year, six to eight students from WRA spend three weeks at the Caterham campus in Surrey attending classes and participating in sports and extracurricular activities. The school's proximity to London, with easy access by train, offers Reserve students an opportunity to attend a variety of Caterham-sponsored activities, including an afternoon at Wimbledon, an evening in London's theater district, museum visits, day trips to Oxford or Cambridge and other cultural and educational opportunities.

In the fall, six to eight Caterham students visit Western Reserve Academy for two weeks, attending classes, participating in sports and taking advantage of trips to Cleveland, Washington, D.C. and other points of cultural and historical significance.

The exchange program is open to WRA juniors, who apply for selection in the spring of their junior year. Selections are made by history department faculty based on student essays and in-person interviews.
