The Optometry Admissions Test (OAT) is a component of a complete application for admission to most optometry schools in the United States and Canada.

About The Oat

The OAT is likely different from any other test you have encountered in your academic career. It is unlike the knowledge-based exams common in high schools and colleges that emphasize memorizing information; optometry schools can assess your academic prowess by looking at your transcript instead. The OAT is not even like other standardized tests that focus on proving your general skills.

Optometry schools use OAT scores to assess whether you possess the foundation upon which to build a successful optometry career. Though you certainly need to know the content to do well, the focus is on thought processes. The OAT emphasizes reasoning, critical thinking, reading comprehension, data analysis, and problem-solving skills.

The OAT’s power comes from its use as an indicator of your abilities: Good scores can open up many opportunities for you. Your power comes from preparation and mindset. Scores earned by examinees are an important part of the optometry school admissions process because they provide a common factor for schools to use in comparing applications for admission. The key to OAT success is knowing what you are up against. Knowing the philosophy behind the test, reviewing the sections one by one, attempting sample questions, mastering methods for each section, and understanding what the test makers really want can help you succeed on the OAT.

The OAT should be viewed as an opportunity to show optometry schools who you are and what you can do, just like any other part of your application. Take control of your OAT experience.

The OAT: A Computer Based Test

The OAT is administered exclusively on the computer and can be taken almost any day of the year. To check in for your testing session, you will need your admission ticket (emailed to you as confirmation of your registration) and two forms of valid, nonexpired identification with signature, one of which must be government-issued and contain a photograph of you, such as a driver’s license, passport, state ID, or military ID.

The first and last names on your admission ticket must match your personal IDs exactly; however, IDs with only middle initial or with no middle name included will be accepted. At the testing center, additional security procedures such as photos or digital fingerprints may be taken to confirm and record your identity.

During the test, time is kept via a countdown timer in the corner of the screen. You will not be allowed to wear a watch and may not have access to a clock. One 15-minute rest break is scheduled for the middle of the test. You may take additional breaks with the permission of the proctor, but the test timer will continue running, and you will lose that time. Even if you are not at the computer, the test will continue to run itself, and successive sections will start automatically if time for the previous section has elapsed.

An on-screen periodic table is provided for only the Survey of Natural Sciences section, and an on-screen calculator is provided for only the Quantitative Reasoning section. The testing center provides a noteboard and marker to use for taking notes and writing out calculations. If you need to replace your noteboard or marker, you may ask the proctor for a new set any time during the test (although if this is during a section, your time will continue to elapse). You will not be allowed to bring your own calculator, writing utensils, or paper.
