The primary purpose of Northeastern State University Oklahoma College of Optometry's OSA (Optometric Student Association) is to promote the profession of optometry to students and encourage high professional standards within the student body. OSA is there for the students to help contribute to and enhance the educational experience of its members. OSA serves as a liason to the optometric profession at the local, state and national level. As such, OSA works closely with the American Optometric Student Association (AOSA) to help acheive it's goals.

OSA provides student-oriented activities to establish good rapport among optometry students. The leadership of OSA represents the student body to the faculty and administration of the College of Optometry through the Dean's Council. This is a forum for us to voice our concerns and ideas to the administration because anything OSA does or sponsors directly affects the College of Optometry.

By paying one set of dues, students at NSU-OCO become members of the OSA, AOSA, Oklahoma Association of Optometric Physicians (OAOP), and American Optometric Association Political Action Committee (AOA-PAC). These dues can also be paid by using points earned through participation in NSU-OCO activities.
