In anticipation of the upcoming flu season and potential increase in restrictions related to the COVID-19 pandemic, all testing candidates planning to test during the winter months of 2021 should submit their application and schedule a testing appointment as soon as possible. There is no guarantee that appointments will not be canceled or rescheduled should restrictions increase, but this ensures the best selection of available testing appointments. 

The OAT is an optometry admission test designed to provide optometry education programs with a means to assess program applicants’ potential for success. The OAT is administered year round by Prometric test centers in the United States, its territories (including Guam, Puerto Rico and the Virgin Islands) and Canada.

The OAT is comprised of multiple-choice test items presented in the English language. The test is developed according to established test specifications. The OAT consists of a battery of four tests on the following: Survey of the Natural Sciences, Physics, Reading Comprehension, and Quantitative Reasoning. In the OAT, both the U.S. customary system and the metric system (Imperial System) of units are used.

Test Preparation

OAT Practice Tests

The OAT program offers practice tests with questions written by actual OAT test constructors.

The intent of the practice tests is to help candidates understand the types of questions that will be asked on the Optometry Admission Test (OAT). These practice tests feature the types of questions and question formats used in the actual test and will mirror the actual test specifications, although some modules/sections have fewer items.
All practice items are copyrighted property. The practice items are intended for the use of educators and students within the educational environment or for individual study and may not be reproduced in any format, whether paper or electronic, without expressed written permission.

This practice test should only be used as a personal resource when studying and preparing for an admissions examination. The number of correct answers will be reported upon completion of each module. Scores will not be provided. 
The specifications of the actual test can change over time; always refer to the current Optometry Admission Test (OAT) Guide for the most current information about the test. The OAT Guide is updated each year and is posted on the OAT web site.
Applicants may choose between the following testing options:
• Individual modules, each available for $20.
• A full practice test, for the discounted price of $100.

Individual Modules ($20 each)

1. Biology 201 (40 items)
2. Organic Chemistry 201 (30 items)
3. General Chemistry 201 (30 items)
4. Reading Comprehension 201 (25 items)
5. Quantitative Reasoning 201 (40 items)
6. Physics 201 (40 items) 

Once purchased, candidates will have 24 hours to access and complete the testing module. When the time expires, the test will end even if you are taking the test at that time.
