The Interim Advantage & History


Founded in 1980, the Center for Interim Programs ("Interim") is the first and longest-running independent gap year counseling organization in the United States. At Interim we have always believed that the process of personal expansion and creative risk-taking is relevant to people of all ages, at any stage of life. Through our own personal explorations and professional experiences, we know first-hand that the perspective, knowledge, and skills gained through a well-planned gap year are critical to one's growth and identity, and as such are a tremendous complement to further personal, academic, and career pursuits.

Our counselors are accredited through the Gap Year Association, having demonstrated excellence in the field of gap year consulting and passed all required standards for ethical, responsible, and risk-managed placements in gap year education.

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 USA. 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.
