Chairs are usually hired for ten-month contracts. The university does not collect information on the tenure of chairs. At ECU, chairs are not rotated.
Departments recruit their own chairs with two names being submitted to a dean who chooses.
A majority of tenured faculty must approve of this choice. Faculty and deans evaluate chairs annually. Chairs receive the data of their evaluations. While faculty vote, deans make final decisions. However, in the past some deans took some initiative when new chairs were being placed.
