Becoming an optometrist, or eye doctor, requires earning a Doctor of Optometry (OD) from a school of optometry. Getting accepted to one of the 20 optometry programs in the United States requires taking the Optometry Admissions Test, or OAT.
What Is the OAT?
The OAT is a standardized exam administered by the American Dental Association (ADA) on behalf of the Association of Schools and Colleges of Optometry (ASCO). What does the OAT measure? This standardized test evaluates a test taker’s conceptual understanding and analytical skills necessary to practice optometry.
Here is everything prospective optometry students need to know about this competitive grad school test. We will go over questions including how long does the OAT take, how the OAT score is calculated, and what is considered a good OAT score.
December 2020 update
Due to the COVID-19 pandemic, Prometric, the global testing services provider, decided to close selected test centers for the OAT exam. While continuing to monitor the situation, Prometric resumed testing where possible. Reopened test centers are strictly following health measures and requiring test takers to wear a face mask during the exam.
If your appointment for the OAT exam is affected, Prometric will notify you and guide you through the next steps: you can choose to cancel or reschedule. You will receive a full refund if your exam payment was processed through Prometric. Your appointment will be rescheduled to a new date depending on when testing will resume. You are entitled to one free reschedule for your exam.
If you are unable to travel to an official testing center because of illness or travel restrictions, do not worry: you can email your concerns to firstname.lastname@example.org and request to reschedule or cancel your appointment.

What Is the Structure of the OAT?
More specifically, how many sections does the OAT exam have? How many questions are on OAT?
The OAT is a computer-administered, multiple-choice test with four sections:
Survey of the Natural Sciences: This 90-minute section includes 100 questions in three subsections: Biology (40 questions), General Chemistry (30 questions), and Organic Chemistry (30 questions). An on-screen periodic table is provided.
Reading Comprehension: test takers will have 50 minutes to complete 40 questions. There are three passages to read, then questions to answer that test comprehension and the ability to analyze scientific content.
Physics: this 50-minute section has 40 questions. Tested topics include vectors, energy and momentum, thermodynamics, magnetism, and optics.
Quantitative Reasoning: OAT’s final section takes 45 minutes to cover 40 questions. Examinees will work on algebra, geometry, trigonometry, and word problems. In the OAT, both the US customary system and the metric system (Imperial System) of units are used. An on-screen calculator is provided, as well as an eraseboard and marker. No personal calculators, writing utensils, or paper are allowed in the testing room.
You can get a more detailed breakdown of covered topics by reading the ADA’s OAT Candidate Guide.
There is no penalty for guessing, so that means you should answer every question before time runs out on the section.
How Long Is the OAT? How Long Does It Take to Get OAT Scores?
The OAT takes four hours and 50 minutes to complete, including an optional 15-minute tutorial, a 30-minute break, and a 15-minute survey after the test. After the test is finished, you will receive an unofficial score report at the test center. Be sure to take your test four weeks before your application deadlines to ensure on-time reporting.
How Is the OAT Scored? What Is a Good OAT Score?
Raw scores for each section are converted to a scale between 200 and 400 in increments of 10 points. Scores range from 200 to 400, with a median score of 300, and a good score is 350.

How Much Does It Cost to Take the OAT?
Exam fees for OAT are $490. A limited number of partial fee waivers are available if the exam fee is not affordable to you. The waiver covers 50% of the OAT fee. Cancellation or rescheduling fees are applied based on the amount of time until the test date.
How Many Times Can OAT Be Taken?
The OAT can be taken an unlimited number of times, with 90 days between tests. After three attempts, you must apply for permission for retesting, which can be done only once per year. Scores cannot be voided after the exam has begun. All scores will be reported to the test taker’s designated colleges or universities.
OAT vs MCAT
The OAT is less complex and lengthy than the MCAT. If you have taken the MCAT, a lot of the same biology and chemistry prep will be applicable, but be sure to review OAT-specific physics and math materials.
How to Study for OAT
Depending how much time you can dedicate per week to studying, plan on two to three months of preparation for the OAT. ADA sells official study materials including practice exams, and offers a list of reference texts for review. Commercial test prep alternatives that include OAT math practice tests are available from Kaplan and The Princeton Review.
