Project Discovery, Trinity Rep's pioneering educational outreach program launched in 1966, annually introduces over 15,000 Rhode Island, Massachusetts, and Connecticut high school students to live theater through matinees as well as in-school residencies and workshops (See: YASI).

Incorporated as "The Foundation for Repertory Theater of Rhode Island, Inc." on March 21, 1963,[6] the group hired Adrian Hall, a New York-based director originally from Texas.
