The academic structure of the college consists of five schools and the library. The Dean is the administrative head of each unit. The schools are: Administration and Business; American and International Studies, Contemporary Arts, Social Science and Human Services and Theoretical and Applied Sciences. Each unit is associated with major and minor programs called convening groups. Convenors are members of the faculty. Deans are faculty members who function as administrators. The ways in which these function vary dramatically. By their own accounts, convening groups behave in ways that are similar to departments in the Schools of Contemporary Arts, Theoretical and Applied Sciences, and to a lesser extent in the Administration and Business. Some convening groups have a large number of faculty (as many as twelve) and over four hundred majors (Communications and Psychology). Others are small (as few as three faculty) and have less than ten majors. In some units, convenors hire and evaluate adjunct faculty, make personnel recommendations and administer the curriculum; in other schools much of that responsibility falls to the Dean. In some units, the convenor position rotates every three years or so, in other schools, convenors have remained in that position for decades.
