We aspire to improve student life at the University of Iowa by encouraging American and international students to engage with each other in productive conversations in which they broaden their communication skills and understanding of differing cultural perspectives.

The Speaking Center, housed in the Rhetoric Department in Rooms 410, 412, and 414 EPB, offers quality, one-on-one and small group tutoring and consultation to students and instructors on campus who would like to work on any aspect of oral communication.

The Writing Center assists with all writing projects, including multimedia projects, at any stage of development. Our services are free and available to anyone in the University of Iowa community. Our job is to help you become a better writer, reader and critical thinker.
