The Optometry Admission Test (OAT) is developed by the American Optometric Association (AOA) and sponsored by the Association of Schools and Colleges of Optometry (ASCO). It is an important examination for those wishing to have a career in optometry. The AOA is an advocacy group representing over 30,000 optometrists in the United States. Beginning in 1987, the exam changed to a format that included four components. They are as follows: a survey of the natural sciences, reading comprehension, physics, and quantitative reasoning.[1]


OAT Study Guide

The OAT is taken by college students seeking admissions to optometry schools. It is used by admissions committees as a component of selection. Every optometry school in the United States mandates this test for applications. The test measures general intellectual ability and understanding of scientific information. Those students interested in this test should seek out an academic advisor who can provide more information regarding the exam. Typically, students must have already gone through one year of college and have taken biology, chemistry and physics classes prior to sitting for the exam. Most students do not take the test until after two years of undergraduate training.[2]

OAT Flashcards

There are several necessary steps one must take when applying to for the OAT exam. First, read the OAT guide which clearly outlines eligibility requirements, rules of conduct, and testing procedures. Next, apply to take the test through the ASCO and pay the $270 exam fee. In your application you are allowed up to 5 schools to receive official scores.[3] Once your application has been processed and accepted, you will receive an email notice giving you instructions for scheduling your test. The OAT is administered by Prometic Test Centers and the exam is given throughout the year. Please be advised that if you must reschedule your test date, additional fees will apply. If you cancel the appointment, no refund will be given. Test-takers are allotted a total of 4 hours and 40 minutes (including pre-test questions and breaks) to complete the computer-based examination. There are a total of 220 multiple-choice questions and each subsection of the test differs in the number of questions and the time allotted.

Test Structure

The Optometrist Admission Test is made up of 220 multiple choice questions. These questions consist of four major content areas: Survey of the Natural Sciences, Reading Comprehension, Physics, and Quantitative Reasoning. Each of these content areas will be scheduled sections during the testing period. There will also be optional tutorial, break, and survey periods. All of these together make up a testing period of four hours and forty minutes.[4]

Test Environment

Each candidate must arrive at the testing center at least half an hour before the test begins. The Prometric Testing Center requires at least two forms of ID, one of which needs to be a photo ID. Food, electronics, outerwear (jackets and gloves), and bags are not allowed in the testing area. For the Quantitative Reasoning section, an on screen calculator will be provided. Two note boards, a marker, and other supplies will be provided by the testing center.[5]

Unofficial scores are available immediately after taking the test, while official scores will be automatically sent within several weeks of the testing date to any school listed on the initial application. If a person desires more scoring reports, additional fees are required. Test scores range between 200 to 400 and are calculated in increments of 10.[6] They are based on the number of correct answers, so educated guesses will not count against a person’s score. While there is no set score to determine passage of the exam, some schools do list what range they expect. For example, the College of Optometry at the University of Missouri-St. Louis states that a score of 270 or above on most sections, and an overall average of 300, is likely to earn a test-taker an interview for admission. Ohio State University lists that a score between 320 and 340 is needed for admission.[7] If a person wishes to retake the exam, they are required to submit a new application and pay the testing fee again. A 90 day wait period is in effect for retests. Anyone wishing to take the exam beyond three attempts must submit in writing. This request must include evidence that you are planning on applying to an optometry school. The OAT does provide reasonable accommodations for those with disabilities. When initially filling out the application form, check the box requesting testing accommodations. Then an applicant must email a completed accommodation request form and an evaluation report from a licensed professional attesting to the disability. Very importantly, do not schedule your test time until you have received approval for specials accommodations.[1]
