The following is a summary of the current graduate school policies regarding course loads for all teaching assistants and research assistants. Physics and astronomy students should usually enroll in 9-10 credit hours per semester, including courses, research hours (if applicable), and seminar (PH/AY 597) when in residence, in order for degree requirements to be completed in a reasonable time.

Graduate assistants must be full-time graduate students during all periods in which they receive financial assistance from the University or associated agencies. The Graduate School imposes the following enrollment limitations:

TA/RA Award Min-Max Graduate Enrollment
0.25 FTE 9-15 semester hours
0.50 FTE 6-12 semester hours

In addition, it should be noted that immigration regulations limit international students to a maximum of 20 hours per week of employment during the academic year, including any combinations of on- and off-campus positions.

A fellowship, as a non-service award, is outside the scope of these policies. Fellows, by the terms of their appointments, are required to undertake full-time graduate study.

Enrollment during the summer is not mandatory for graduate teaching and research assistants
