The Wesleyan-Trinity Summer School was a joint summer school program which took place in 1942, allowing students to accelerate their education before joining the military.

During the first year of America's involvement in World War II, though enrollment did not sharply decline, Trinity encouraged students to embrace as much of their education as possible before following their “obligations to their nation.” In order to complete this goal, the College introduced several measures to accelerate the undergraduate curricula, such as shortened vacations and exam periods, and an earlier Commencement which took place on May 17, 1942.

That summer, the College introduced the Wesleyan-Trinity Summer School, which offered a joint summer term, where from May 18 to June 27, Wesleyan faculty offered courses in Middletown, followed by six weeks of courses in Hartford taught by Trinity faculty.

The project was successful despite the original shock, with President Ogilby stating, “Trinity and Wesleyan, close neighbors and therefore naturally rivals, may be safely termed today natural friends.”

The program did not continue the following year, despite its success. Instead, Trinity followed a three-term school year.
