Course Requirements

To assure that you are ready for optometry school, ICO requires a series of college-level, pre-optometry courses prior to admission. Completion of additional science coursework, particularly human-based biological science, is strongly recommended. Only grades of C or higher will be accepted. Classes from 4-year universities are preferred. These courses may be planned or in-progress at the time of your application.

ICO will accept Advanced Placement courses for the prerequisites as long as you received the appropriate number of credit hours. These courses must appear on your official college transcript or in a letter from your registrar.

We gladly accept applicants from any and all undergraduate majors. Additionally, exceptional non-degree candidates may be considered, as long as they have completed a minimum of 90 semester hours or 135 quarter hours prior to enrolling at ICO.
