The 4-1-4 or the interim term is used by an increasing number of colleges and universities in an effort to enrich or rejuvenate their educational program by providing a special new kind of learning experience for the entire college community. Generally a brief period between semesters or quarters, the interim term can take several forms: (1) it can have a program built around a single theme; (2) it can have different themes for each class; (3) it can have a special program for freshmen and varied programs for others; (4) it can place primary emphasis on independent study; or (5) it can be a combination course - independent study program; This digest lists all the colleges (for which information was available) that have adopted or are considering an interim term, and the colleges following each of the different approaches to the interim term.
