All students must complete a major. The major programs approved by the Faculty Assembly are called standing majors. Most of these are in a single field and are also called departmental majors (e.g., History, Philosophy, Physics). Others, called multiple-field interdisciplinary majors, combine two or more fields (e.g., International Business).

Standing majors, whether single-field or interdisciplinary, eligible for a B.A., B.S., or B.S.N. degree typically consist of 40 to 60 required credits, including prerequisites and supporting courses. Most single-field majors have a minimum of 30 and a maximum of 40 credits within the field. For a multiple-field major, each of the constituent core fields normally consists of 15-30 required credits.

Some majors require the completion of one or more courses which do not count toward the maxima indicated above.

A student must earn a minimum cumulative GPA of a 2.000 in the courses required for completion of the declared major(s) unless a higher minimum is specified by the individual program. At least 15 of the credits required for a major must be earned at Linfield.
