As the state of Oklahoma's public liberal arts college, USAO's mission is to provide the public with a distinctive and accessible liberal arts and sciences education.[36] The academic program centers on a required 46-hour Interdisciplinary Studies Core Curriculum, which is a prescribed set of courses that encompass history, science, art, mathematics, literature, philosophy, economics, art and theatre.[37][38] Many of these classes are team-taught by two or more instructors in order to encourage interdisciplinary learning.[37][38][39] The Core Curriculum Courses are distributed throughout a student's four years at USAO, culminating in a Senior Seminar class and completion of an interdisciplinary research project.[40] While working through the core curriculum, students simultaneously pursue traditional majors in a variety of subject areas.[36] USAO offers 22 majors and several pre-professional programs.[41] The University is organized into four divisions: Arts and Humanities, Social Sciences and Business, Science and Physical Education, and Education and Speech-Language Pathology.
