Aspiring dentists preparing for the Dental Admission Test often ask: what is on the DAT? This question is crucial because the DAT isn’t just another academic test—it’s a comprehensive exam designed to evaluate your readiness for dental school. Created and administered by the American Dental Association, the DAT exam plays a major role in the dental school application process across the U.S. and Canada.

To succeed, it’s important to understand the test structure, content areas, and how each section contributes to your overall DAT scores. This guide provides a detailed breakdown of each part of the exam so that you can prepare with purpose and clarity.

General Overview of the DAT

Administered by the ADA

The Dental Admission Test DAT is offered year round at authorized Prometric test centers. Students register through the ADA website and receive a Dental Personal Identifier Number to complete the process. The test is accepted by all U.S. and most Canadian dental schools, and it’s a core requirement for entry.

Test Format

The DAT is a computer-based exam that includes:

  • Four main sections
  • A total of 280 multiple choice questions
  • About 4 hours and 15 minutes total testing time (plus optional breaks)

Each section is scored separately and also contributes to composite scores like the academic average and total science score.

Section 1 — Survey of Natural Sciences

The Survey of Natural Sciences is the first section of the test. It consists of 100 multiple choice questions and is divided into three subsections:

Biology

Expect questions on:

  • Cell structure and function
  • Genetics and molecular biology
  • Evolution and animal behavior
  • Integrated relationships diversity and ecology
  • Physiology and developmental biology

This part tests both factual recall and conceptual understanding, with an emphasis on basic mechanisms and systems.

General Chemistry

This portion includes:

  • Stoichiometry and reactions
  • Thermodynamics and heat transfer chemical kinetics
  • Acid-base chemistry and buffers
  • Periodic properties and atomic structure
  • Kinetic molecular theory

The focus is on calculations, reasoning, and laboratory theory.

Organic Chemistry

Topics covered:

  • Major functional groups and nomenclature
  • Reaction mechanisms and synthesis
  • Isomerism and stereochemistry
  • Integrated relationships structure, reactivity, and basic techniques

This subsection rewards strong conceptual frameworks over rote memorization.

Section 2 — Perceptual Ability Test (PAT)

The Perceptual Ability Test contains 90 questions and no reading or science content. It measures spatial visualization skills and three dimensional manipulation.

PAT Subsections

  • Keyholes: Choose the shape that fits into a 3D opening
  • Top-Front-End (TFE): Visualize 3D objects from different views
  • Angle Ranking: Order angles from smallest to largest
  • Hole Punching: Predict paper hole locations after folds
  • Cube Counting: Determine how many cubes are visible
  • Pattern Folding: Visualize how flat patterns fold into 3D figures

This section doesn’t rely on prior academic knowledge but requires mental rotation, attention to detail, and practice. Tools like DATBooster’s PAT generators can significantly sharpen your skills here.

Section 3 — Reading Comprehension

The Reading Comprehension Section contains 50 questions based on three passages related to scientific topics. Each passage is followed by questions that test your understanding, interpretation, and critical thinking.

Types of Questions

  • Main idea and summary questions
  • Tone, attitude, and purpose
  • Specific detail and inference
  • Application and integration

No prior knowledge of the topics is needed, but test takers must interpret and analyze the information efficiently. The comprehension test challenges your ability to digest and retain information from dense texts under pressure.

Section 4 — Quantitative Reasoning

The Quantitative Reasoning Section consists of 40 questions that test your problem-solving and math skills. This is the final section of the exam.

What’s Tested

  • Algebra and functions
  • Absolute value and inequalities
  • Geometry and trigonometry
  • Mathematical problems involving proportions and ratios
  • Graphical analysis and data interpretation
  • Quantitative comparison problems
  • Data analysis, statistics, and probability

While a calculator is available on screen, the emphasis remains on logic and quick mental calculations. The quantitative reasoning test challenges both accuracy and efficiency.

Scoring the DAT

Raw vs Scaled Scores

Every question you answer contributes to a raw score, which is then converted into a scaled score ranging from 200 to 600 using a statistical equating process. You receive eight standard scores, including:

  • Biology
  • General Chemistry
  • Organic Chemistry
  • Reading Comprehension
  • Quantitative Reasoning
  • Perceptual Ability
  • Total Science Score
  • Academic Average

Your official scores are sent to the schools you selected during DAT registration. A high score improves your chances in competitive admissions.

Preparing for the DAT

Practice Is Essential

Since the Dental Admission Test requires mastery across multiple subjects, strategic preparation is key. Use practice tests that reflect the real test environment, format, and difficulty.

DATBooster is one such platform that offers high-quality content aligned with the ADA’s test specifications, including realistic PAT generators and in-depth explanations. The platform’s dashboard helps you monitor performance trends and identify where your focus should be.

Review by Section

Focus on each section individually, identifying weak points. For example:

  • Use flashcards for organic chemistry reactions
  • Sketch diagrams to build perceptual ability
  • Read complex articles to improve reading comprehension
  • Solve timed sets to sharpen your quantitative reasoning

Balance review with self-testing to ensure long-term retention and improved performance.

Know Your Test Center and Date

Schedule your exam at a local testing center, ideally several weeks in advance. Select a test date that gives you enough time for content review, test-taking practice, and stress management.

DATBooster also offers a customizable study schedule tool to help you plan efficiently—especially useful for students balancing classes or work during their DAT prep.

Final Thoughts

The DAT is a rigorous, multidimensional exam that evaluates your academic background and cognitive abilities across diverse content areas. From chemical and physical properties in science to data analysis in math and spatial reasoning in PAT, it challenges how well-rounded you are as a future dental student.

Understanding what is on the DAT empowers you to build an efficient, focused study plan—one that targets high-yield areas while reinforcing your strengths. Preparation should be strategic, using tools designed to match the real testing experience.
