Assistantships - Department of Computer Science - Purdue University Skip to main content


By the CS Department:

For 2021-2022 half-time (20 hours per week), graduate assistantships start at a salary of $19,188 for the academic year (fall and spring semester).

Tuition for graduate assistants is remitted. Fees for incoming graduate assistants in fall 2021 are about $400 per semester plus a differential fee of $562 per semester. International students pay an additional $145 per semester.

Students that are graduate assistants in the spring and fall semesters of a calendar year are eligible for tuition and fee reduction in the intervening summer even if they do not hold an assistantship in the summer. Others must be graduate assistants in the summer.

The University provides medical insurance for graduate assistants employed at least half-time for at least one semester. 

The tasks of graduate assistants usually are teaching, grading, consulting, developing software, maintaining systems, or conducting research.

The usual and expected course load for half-time assistants is three graduate courses per semester or at least equivalent thesis research credit hours.  In the summer, graduate assistants are obligated to register for a minimum of three graduate hours during at least one of the summer modules.

In semesters, the term of service begins one week before the beginning of classes and ends on the Tuesday following the end of final examinations.

Graduate students teaching for the first time in the CS department must attend all Teaching Orientation sessions (Fall semester beginners) and complete online training the week before their first semester of teaching.

Teaching assistants whose native language is not English must be certified by the Oral English Proficiency Test (OEPT), or a minimum score of 27 in the speaking section of the internet-based TOEFL (TOEFL iBT), or a minimum score of 8 on the academic International English Language Testing System (IELTS).

Teaching assistants and other graduate assistants without assurance of an assistantship in the summer must make a special request for support in the summer.

Support is contingent upon availability of departmental funds and satisfactory academic progress, as well as satisfactory performance in all duties assigned.  For students with a PhD degree objective, this includes successfully completing the Core Course Requirement by the end of the fourth semester.

All University fees and tuition are subject to change without notice.
