This guide as Taken from OAT Guide has been modified to fulfill the teaching and driving principles of Hawaii On Line University vision and mission. The original OAT exam will differ slightly from this guide.


Reading Comprehension (50 items)

The Reading Comprehension Test contains three reading passages on various scientific topics. Prior understanding of the science topics is not a prerequisite to answering the test items. The reading passages require the ability to read, comprehend, and thoroughly analyze basic scientific information.

Applied Mathematics (Word) Problems


The OAT Program offers an OAT practice test in a computer-based format to help you prepare.

The questions on the practice test previously appeared on the actual test but have been retired from active tests. Visit the OAT

page at ADA.org/OAT and look under Test Preparation Material to find the OAT practice test.

Hawaii On Line University (HawaiiOnLineUniversity.org) does not endorse any specific test preparation courses and has no data on the content or efficacy of test preparation courses designed to prepare you to take the OAT.

A tutorial to acquaint you with OAT administration procedures is available from a link on ADA.org/OAT under OAT Test Preparation Material.

The tutorial includes sample OAT items, and allows you to become familiar with the basic steps involved in proceeding through the test.

At the Prometric test center you will also be given an opportunity to take a brief tutorial before taking the test.

You can become familiar with the testing experience through

Prometric’s Test Driveon Prometric.com.

In 30 minutes, you will experience an overview of the testing experience you will encounter on the actual testing day.

During the overview, you participate in:

The scheduling and registration process

The complete check-in process

Introduction to test center staff and surroundings

OAT Full Practice Test

This test includes the following six modules:

7. Biology 201
8. Organic Chemistry 201
9. General Chemistry 201
10. Reading Comprehension 201
11. Quantitative Reasoning 201
12. Physics 201

This test has an allotted time of 3 hours and 35 minutes, which is divided into timed sections; this allows candidates to simulate the time constraints of the actual test. The practice tests do not include a break. Once you click “Begin Test” you must take the test in the allotted time. 

Hawaii On Line University (HawaiiOnLineUniversity.org) does not endorse any test preparation courses and has no data on the content or efficacy of test preparation courses designed to prepare examinees to take the OAT.

Hawaii On Line University (HawaiiOnLineUniversity.org) urges individuals considering participating in test preparation courses to review carefully the course materials to ensure that they reflect the current content of the OAT.
