Graduate Assistantship Stipends

Rates for GA stipends can be found in the link below. The established rates are minimums, individual faculty or units are permitted to use a higher rate. A graduate assistant supported by an external grant is paid the rate of the unit of the principal investigator. Units without established rates pay the rate of the unit in which the student is enrolled.

The standard graduate assistantship is one-half time (50%).OSPA budget spreadsheets should be set up to use the full-time (100%) rate at half-time (50% or 0.5) effort.

Postdoctoral Fellows are contracted through the Graduate School. Effective March 1, 2016, the salary rates for Fellows will vary depending on the level agreed upon by the unit and the post-doctoral fellow, but at no less than the federal or state minimum wage, whichever is higher.
