Information For Postdoctoral Scholar Appointments

What is a Postdoctoral Scholar?

Postdoctoral Scholars conduct research under the guidance of a Faculty Mentor. The postdoctoral appointment prepares researchers for careers in academia, industry, government, the nonprofit sector or numerous other fields. For many, especially those in the physical and life sciences, postdoctoral traineeships are a critical step in securing future employment.

A postdoc is an individual who:

  • Has been awarded a doctoral degree (or equivalent) within the past ten years.
  • Will pursue a full-time program of advanced training and research under the direction of a faculty member with an appointment in an academic department or organized research unit.
  • Will be supported by campus research grants or contracts, by fellowships administered by the campus, or by other external sources.
  • May not have had more than five years of postdoctoral experience, including at other institutions.
  • May not have held or hold a tenure-track professorial appointment (assistant professor, associate professor, or professor).

Postdoctoral Scholar Categories

Postdoctoral appointment titles differ with respect to compensation, benefits, and taxation. The source of support determines the category of the postdoc. UC Merced, postdoctoral appointments fall into four categories.

  1. Postdoctoral Scholar - Employee, Job Code 3252
    An appointment is made in the title "Postdoctoral Scholar - Employee" when: The agency funding the salary requires or permits the appointee to be an employee of the University, or whenever General Funds, Opportunity Funds or other University discretionary funds are used to support the position.
  2. Postdoctoral Scholar - Fellow, Job Code 3253
    An appointment is made in the title "Postdoctoral Scholar - Fellow" when the Postdoctoral Scholar has been awarded a fellowship or traineeship for postdoctoral study by an extramural agency and the fellowship or traineeship is paid through a university account.
  3. Postdoctoral Scholar - Paid Direct, Job Code 3254
    An appointment is made in the title "Postdoctoral Scholar - Paid Direct" when the Postdoctoral Scholar has been awarded a fellowship or traineeship for postdoctoral study by an extramural agency and the agency pays the fellowship or traineeship directly to the Postdoctoral Scholar, rather than through the university. Such appointments shall have a "without-salary" status.
  4. Interim Postdoctoral Scholar – Employee, Job Code3256
    An appointment is made in the title “Interim Postdoctoral Scholar--Employee” when UCM graduate students who recently obtained their PhD degree or equivalent who need a short-term (cumulative total of 12 months in one or multiple) appointment to complete an existing project from their graduate educational programs before moving on to other employment.

Postdoctoral Scholars may be assigned to more than one Postdoctoral Scholar title concurrently depending on university and extramural funding agency requirements.

Terms of Appointment

All postdoctoral appointments are initially for a two-year period. All postdocs are required to work and be compensated at 100-percent time. Exceptions to less than full-time appointments must be initiated by the postdoc and endorsed by the appropriate university officials.


The reappointment process must be initiated by the current Postdoctoral Scholar's PI or Faculty Advisor, and processed through the School or ORU. Make sure to speak with your PI or Faculty Advisor several months prior to termination of the existing appointment to determine if a reappointment will be offered.
