NOTE: You must complete 9 of the 13 prerequisites before you apply. If you do not have 9 of the prerequisites done at the time of application, your file will not be reviewed and you will not be considered for an interview or seat in our next class. All 13 pre-requisites must be completed with a C or better by the time of matriculation, or you will lose your seat for the class.

Note: These prerequisites must be completed at an accredited, educational, English-speaking institution within the United States or Canada.

Ohio State’s course numbers for the prerequisite classes are listed below. If you are unsure whether a course at your school is equivalent to the course offered by Ohio State, you can utilize the course evaluation website. This website contains equivalencies for numerous schools.

Ohio State Required Course Numbers

Physiology 3200 or EEOB 2520 or PHR 3100
Biochemistry 4511
Biology 1113 & 1114
*Chemistry 1210 & 1220
*Organic Chemistry 2510 & 2520

Second Writing Course
Microbiology 4000
Physics 1200

*Labs: If a lab is required as part of the specific course number, then the lab IS required. If the lab is listed as a separate course number, it is NOT required.


Can I take Anatomy and Physiology together?

Yes. However, if you take Anatomy and Physiology as a combined course you will be required to complete both levels of the course (two semesters). One semester of the combined course will not meet the requirement. These are two very important courses and are often the areas where our incoming students struggle.

When should I take Anatomy?

We recommend taking Anatomy as late as you can. Our curriculum is strongly anatomy-based and many students struggle with this course. The fresher the material is in your mind, the better off you will be in Anatomy as a D1. If you are able to wait to take Anatomy, we highly recommend it.

When should I take all the prerequisites?

We recommend completing Biology, Inorganic Chemistry, Biochemistry, Microbiology before you complete the DAT. These courses will help prepare you for the material on the DAT. There are four sections on the DAT: Survey of the Natural Sciences (Biology, General Chemistry, and Organic Chemistry), Perceptual Ability, Reading Comprehension, and Quantitative Reasoning.

Do AP Credits count for the prerequisites?

As long as your institution gives you credit for AP credits and it is reflected on your transcript then yes. However, we still recommend taking the courses at your institution as it will better prepare you for the DAT.

Should I retake a prerequisite if I got a C?

We require a C or better on all prerequisites, but it would be for your benefit to retake it. You will be tested on these courses on the DAT, and having a thorough knowledge of the material will help you to test well. When retaking classes, we average the two grades. So although we will still see the C, it will help improve your GPA which will also improve your chances of being accepted. If your university does not allow you to retake a course that you received a passing grade in, please contact the Office of Admissions for further counseling.

Can I take the prerequisites at a Community College? 

Yes, however we recommend taking any course with a lab component at a 4-year institution. This will better prepare you for the rigor of the DAT and dental school curriculum.

Can I take the prerequisites online? 

No. All courses must be taken in-class.

Do I need to take a lab?

If the lab is the same course number and is required for the course, then it is required. However, if the lab stands on its own and is a different course number then you are not required to take it. For example, if you take Organic Chemistry at Ohio State, Organic Chemistry I is Chemistry 2510. Organic Chemistry Laboratory I is Chemistry 2540. Since the lab is a different course number, you are not required to take it.

Do prerequisites ever expire?

We accept all prerequisite coursework completed within the last 10 years. If you took a prerequisite greater than 10 years ago, you will need to retake the course. The only exception is English, which we will accept if it was taken more than 10 years ago.

Do you accept prerequisite courses taken outside of the United States?

We only accept prerequisite courses completed at an accredited, educational, English-speaking institution within the United States or Canada.
