The OAT consists of four separate tests: Survey of the Natural Sciences (biology, general chemistry, and organic chemistry), Reading Comprehension, Physics and Quantitative Reasoning.
The test takes between 275 to 300 minutes depending on the number of pretest questions to complete.
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 test.
The Optometry Admission Test is computerized and examinees are allowed to take the test 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 test and/or request additional copies of score reports online and view the Optometry Admission Testing Program–Online Candidate Guide by visiting www.opted.org.
