ENHANCING THE POSTDOCTORAL EXPERIENCE FOR SCIENTISTS AND ENGINEERS: A Guide for Postdoctoral Scholars, Advisers, Institutions, Funding Organizations, and Disciplinary Societies
How Is the Duration of a Postdoctoral Appointment Determined?
Responses to this question were divided fairly evenly. The largest number (58 percent) reported that the duration of an appointment may be determined primarily by the adviser at any time during the appointment. Almost as many (55 percent) reported that duration is determined primarily by the source of funding and/or funding availability. Some 45 percent reported that duration is determined before a postdoc 's arrival.
Many institutions reported firm limits on postdoctoral terms (typically 3, 4, or 5 years). Others allowed for extensions “in special cases, ” which sometimes required the approval of an administration officer. Other policies were 1) to appoint postdocs for a year at a time, with renewal depending on funding and performance, and 2) to allow the length of training to vary by field and source of funding, with no suggested limit.
COSEPUP Survey Results
when viewed from the perspective of citizenship for all science and engineering doctoral fields, but in the biological sciences, chemistry, and especially in physics temporary residents spend longer periods in postdoctoral positions. The 1998 Association of American Universities report11 recommended limiting the total postdoctoral experience to six years; some universities now impose five-year limits, with exceptions for such circumstances as illness, childbirth, a need for exposure to multiple fields, or a need to finish a project that is in an advanced stage. The COSEPUP survey results suggest that institutions have a wide variety of policies on postdoctoral terms, and many institutions allow the adviser to determine the length of the term at any time during the appointment (see Box).
Multiple postdoctoral positions.
In some fields, such as neuroscience, genetics, and epidemiology, more than one postdoctoral position may be useful to gain multidisciplinary expertise. In other fields, a tight job market forces some researchers to complete two or even three postdoctoral appointments while they hunt for jobs. In some cases, multiple postdoctoral appointments may bring many years of low compensation and a lack of security and stability that is demoralizing and stressful. This is of special concern for postdocs with families. In other cases, researchers may continue beyond their postdoctoral term to spend their careers in successive soft-money positions they find challenging and rewarding.
Unmet expectations.
By design, the experience of postdocs should be professionally productive and career enhancing. For many of them, however, the
