DAT Biology Test Specifications to be Updated in January 2022

Updates to the DAT Biology test specifications will be implemented in January, 2022. Students who plan to take the DAT during or after January, 2022 are encouraged to review the updated specifications provided at the link below. The updated Biology test specifications include several new topics that were not previously covered on the examination.

DAT Practice Tests

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

The intent of the practice tests is to help candidates understand the types of questions that will be asked on the Dental Admission Test (DAT). 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 than the actual test. 

All practice items are the copyrighted property of the American Dental Association. 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 of the ADA.

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 Dental Admission Test (DAT) Guide for the most current information about the test. The DAT Guide is updated each year and is posted on the DAT 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 101 (40 items)
2. Organic Chemistry 101 (30 items)
3. General Chemistry 101 (30 items)
4. Reading Comprehension 101 (25 items)
5. Perceptual Ability 101 (30 items)
6. Perceptual Ability 102 (30 items)
7. Perceptual Ability 103 (30 items)
8. Quantitative Reasoning 101 (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.

The individual modules for DAT are identical to the modules included in the Full Practice Test, except that there are two additional modules provided for the Perceptual Ability Test that are not in the Full Practice Test. 

DAT Full Practice Test

This test includes six modules ($100 for all six):

1. Biology 101 
2. Organic Chemistry 101
3. General Chemistry 101
4. Reading Comprehension 101
5. Perceptual Ability 101
6. Quantitative Reasoning 101

This test has an allotted time of 3 hours and 5 minutes, divided into timed sections 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. 

Please refer to the DAT reference texts below for helpful resources while studying for the test.
