The school says the graduates selected alumna Joy Harjo to deliver the address at the May 10 ceremony.
At 16, Harjo enrolled at the institute to study painting and theatre. She graduated in 1968 and went on to receive degrees from the University of New Mexico and the University of Iowa.
Harjo has published seven poetry books and has received several awards, including the New Mexico Governor's Award for Excellence in the Arts.
The institute will also award an honorary doctorate to Navajo artist Tony Abeyta.
Institute President Robert Martin says Abeyta and Harjo are examples of what IAIA's visionaries sought to create—revolutionary artists who push innovation and imagination in Native arts.
