What are the benefits of an assistantship?

A 1/2 time graduate assistantship allows out-of-state students to be assessed Iowa-resident tuition charges. Students receive health insurance coverage and a monthly stipend. In addition, Ph.D. students with 1/2 time appointment will receive a 100% tuition scholarship, completely offsetting the cost of tuition (students are still responsible for student fees of around $700/semester). Tuition scholarships are only given to those students who have a 3.0 or higher GPA.
