Teaching Duties. Contingent faculty members in higher education are non-tenure track faculty, adjuncts, postdocs, lecturers, or instructors. R. Bowden and L. Gonzalez researched whether contingent faculty members are different from tenure-track faculty members with regards to teaching, research, and service in the article

“The Rise of Contingent Faculty: Its Impact on the Professoriate and Higher Education” (Journal of Applied Research in Higher Education, Vol. 4, No. 1, pp. 5–22). A hypothesis test was conducted to decide whether the mean number of classes taught for credit per semester was less for contingent faculty than for tenure-track faculty.
