The following is a breakdown of the number of tenure track slots that exist in a few selected departments. Though the number of faculty who actually teach each year varies due to sabbaticals and administrative assignments, these absences are filled by visiting faculty members. Multi-disciplinary programs are staffed by existing tenure track faculty from other departments; very few multidisciplinary programs have tenure track faculty only assigned to the program. In addition to the tenure track faculty, some departments maintain other part time positions, such as lab coordinators or lecturers. —Emma White, Contributing Editor
