    Key Takeaway

    Starting in 2022, the DAT is adding new material to the biology section. The new material falls under 5 topics:

    • Diversity of Life: Viruses, Archaebacteria
    • Genetics: Genomics, Gene Expression, Epigenetics

    Don't worry, we got your back! DAT Bootcamp has been updated to cover exactly what you need to know on these new topics so you’re prepared for 2022 DAT. By studying with DAT Bootcamp, you’ll be the most prepared to ace the changes made to the 2022 DAT biology section.

    Studying for the OAT? The ADA develops both the DAT and OAT, and the same changes apply.

    Why did the ADA make changes?

    The ADA periodically updates the DAT to make sure it matches up with what you’re learning in your college classes. They also survey dental school professors to see which topics are most important to know for success in dental school.

    During the latest Biology Readiness Survey in 2018, the ADA identified a few new areas they want to include questions on for the DAT. Namely: Viruses, Archaebacteria, Genomics, Gene Expression, and Epigenetics.

    See the current biology test specifications below, vs. the updated 2022 biology test specifications:

    Key Changes

    Topics Added

    • Diversity of Life: Viruses, Archaebacteria
    • Genetics: Genomics, Gene Expression, Epigenetics

    **Topics Removed

    • Cell and Molecular Biology: origin of life
    • Developmental Biology: fertilization, descriptive embryology, developmental mechanisms, and integrated relationships

    **Note on Topics Removed

    It may seem like some content has been removed, however, it’s just been reorganized and still being tested. For example:

    While the “Six Kingdom, Three-Domain System” has been removed from the 2022 specifications (the Three-Domain System represents 1. Archaea, 2. Bacteria, and 3. Eukarya domains), the three domain system is still the currently accepted system further subdivided into the Six Kingdom System (Plants, Animals, Protists, Fungi, Archaebacteria, Eubacteria). Its removal from the test specifications is just a reorganization of how this information is displayed.  

    “Archaebacteria” is underlined in the new 2022 specifications, however this is just a re-representation of “archae” that was present in the previous specifications.

    While the Developmental Biology section of the 2021 specifications has been removed, the Reproductive System is still present in the 2022 Structure and Function of Systems section. The Reproductive System will now cover the developmental stages of fertilization and embryology which were removed from Developmental Biology. Developmental Mechanisms now appears under Genetics. Basically, nothing changed with developmental biology. This is just a reorganization of this table.

    DAT Bootcamp Has Been Updated for the 2022 DAT Bio Changes

    We’ve done the research for you to find the highest-yield information on the new topics and what comes up most often in the DAT exams. We’ve been updating our practice tests and review material right along with the exam.

    We added over 150 new questions that cover everything that you need to know, and nothing you don't. Here’s a few sneak peeks of the new questions:
