Faculty are appointed to perform research, teaching, or service on either a nine or twelve-month basis which is referred to as the "service period."
Faculty appointments must be classified as either a nine- or twelve-month appointment, but may not be both. In either case, salary is paid and benefits are provided all twelve months of the calendar year both to provide a consistent monthly income and to enable the provision of University benefits across the full calendar year.
Certain faculty employment policies differ depending on whether an individual holds a nine- or twelve-month appointment and, in such cases, the relevant policies will often stipulate which benefits or privileges apply to nine-month faculty, twelve-month faculty, or both.
For specific policy provisions regarding either 9- or 12-month faculty members, refer to the Tenure Code or the detailed text of the relevant personnel policy.
