Optometry Admissions Test

The Optometry Admissions Test (OAT) is a standardized examination designed to measure general academic ability and comprehension of scientific information. The OAT is sponsored by the Association of Schools and Colleges of Optometry (ASCO) for applicants seeking admission to an optometry program.

The OAT consists of four tests: Survey of the Natural Sciences (Biology, General Chemistry, and Organic Chemistry), Reading Comprehension, Physics and Quantitative Reasoning. At least one year of college education, which should include courses in biology, general chemistry, organic chemistry and physics, is required prior to taking the OAT. Most students, however, elect to complete two or more years of college prior to taking the exam. The OAT exam is computerized, and examinees are allowed to take the OAT an unlimited number of times but must wait at least 90 days between testing dates. However, only scores from the four most recent attempts and the total number of attempts will be reported. You can submit your application for the OAT examination and/or request additional copies of score reports online.
