DAT Biology Test Updates 2022: All You Need To Know

With the overwhelming content length, DAT Biology has always been a dreadful experience for aspiring dental students. Considering how much they have to cover in such a short period often demotivates them to push through the preparation. To top it all off, unwarranted changes in the syllabus are the last thing that students need to stand between their goals. However, changes are inevitable, and the DAT is no exception either.

So, the best way to deal with them is to prepare yourself early. If you are planning to take the test anytime soon, you might be aware of the recent DAT Biology Test updates. Even if the thought may seem uncomfortable at first, there is light at the end of this tunnel. The first step is to familiarize yourself with the updates and skim through the preparation tips. The article covers the details you need to know for DAT Biology proceeding 2022.

So, without any further delay, let's dive in.

Table Of Contents


  • The standardized assessment test for dental admissions is the DAT.
  • Applicants face a set of 100 questions in the DAT section. There are three categories of the paper containing Biology (40 questions), General Chemistry (30 questions), and Organic Chemistry (30 questions).
  • Each of these subsections has individual markings, so students have to meet the score criteria in each of them to do well on the test.
  • One of the toughest core subjects to crack, DAT Biology, needs significant time and energy from the students if they want to ace it.
  • Not to mention, the ADA makes certain changes in the question patterns, adding to the course content. Thereby, making the preparation a lot more daunting, especially for students taking the DAT for the first time.
  • As the 2022 DAT Biology content is revised once again, we have briefly discussed the material classification here.
  • A proper understanding of the course content and plan supported by sufficient study materials greatly helps students to take the leap of faith.

2022 DAT Biology Tests: Familiarizing With Changes

The American Dental Association, ADA makes periodic changes to the DAT. It is a common practice. This is simply to keep up with what the students are learning in college classes. The board surveys dental school professors to identify the most important topics for dental school students.

Thereon, according to these results, they make certain changes to the questions. Similarly, following the 2o18 Biology Readiness Survey, the ADA realized a few more areas that need to be included in the DAT. Thus, the 2022 Bi0logy tests now have additional concepts regarding Viruses, Genomics, Epigenetics, Gene Expression, and Archaebacteria.

The DAT biology test comprises the following elements:

  1. Cell and Molecular Biology
  2. Evolution, Ecology & Behavior
  3. Vertebrate Anatomy & Physiology
  4. Developmental Biology
  5. Diversity of Life (Added)
  6. Genetics (Added)

And this current pattern has also evolved. Earlier the ADA designed the DAT Biology section had questionnaires focused on the molecular context of life. This meant, that with a basic understanding of the concepts and the biological knowledge, you could easily do well in this section. But the stance is not the same anymore, the ADA has completely revamped the pattern. Therefore, it is important that you can substantial knowledge first, and then connect the different aspects to your other core courses. For instance, organic chemistry or biochemistry to begin with. This is a great way to not only retain the memory of the lessons but also implicate their practical correlations.

Current Vs. Updated Specifications: DAT Biology Test 2022

Given how the test updates may seem a tad bit confusing, here is a brief picture from both ends.

  • Diversity of Life: Some of the expanded areas cover Archaebacteria and viruses.
  • Genetics: This section alone takes in three categories Gene Expression, Genomics, and Epigenetics.

Shifted Topics

  • Origin of Life- Molecular and Cell Biology
  • Developmental Biology: Developmental mechanisms, fertilization, embryology, integrated relationships, fertilization, and so on so forth.

Now, you might have a misconception that the Developmental Biology section has been eliminated from the 2022 specification. However, this is a mistake. The topics have only been shifted to other sections of the Biology Test, rather than being removed.

Developmental Biology is still completely present in the updated tests. So, don't neglect the concepts of fertilization, embryology, etc under a false impression.

For example, the Six Kingdom, Three-Domain System is no longer present in 2022 specifications. Here, the Three-Domain System consists of Archaea, Bacteria, and Eukarya domains. And they are all still a part of the accepted system under the Six Kingdom System subdivision, which contains “Plants, Animals, Protists, Fungi, Archaebacteria, and Eubacteria.” The elimination of the specification is only a redistribution of the displayed information.

Likewise, the Reproductive System is still included in the 2022 Structure and Function of Systems section, despite the removal of the Developmental Biology segment. Essentially, the developmental stages of fertilization and embryology fall under the Reproductive System now. On the other hand, you can find the Genetics segment with the Developmental Mechanisms category.

Likewise, the 2022 specifications have the term “ Archaebacteria” underlined. This is only a re-representation of the previous specification term “ archae”.

Therefore, there have been no changes in the developmental biology segment. The entire proposition is a reorganization of the content present.

How Has DATPrep Reflected These Changes?

If you have been worried about missing out on key topics or updates, you are up for some good news.
