The Interim Advantage, Team & History


Founded in 1980, the Center for Interim Programs is the first and longest-running independent gap year counseling organization in the United States. At Interim, we believe that the process of personal expansion and creative risk-taking is relevant to people of all ages, at any stage of life. The growth, perspective, and life experience gained through a well-planned gap year is a tremendous complement to one's formal education and work.

The Center for Interim Programs was originally founded in 1980 by the late Cornelius Bull whose career in academia spanned 28 years as teacher and headmaster. In his daily work with students, Cornelius saw the need for a complementary path of learning through hands-on, in-the-world experience. Prior to the advent of the Internet, he compiled a comprehensive database of unique program options, and the Center for Interim Programs was created as the first independent gap year counseling organization in the U.S. Its purpose was to assist students in making a more effective transition from high school to college and for college students to evaluate what they wanted to achieve in their college careers and beyond.
