How to Prepare for the OAT: Tips and Strategies for Optometry School Applicants

/

What is the OAT? [Optometry Admission Test Explained for Students] | Study Alpha Academy Introduction: Why the OAT Matters for Aspiring Optometrists If you’ve set your sights on becoming an optometrist, one of the first major steps on the path to optometry school is the OAT Exam (Optometry Admission Test). This standardized, computer-based test is administered year-round and is a critical part of your optometry school application package.

Designed to assess scientific knowledge, critical thinking, and problem-solving skills, the OAT ensures that students are prepared for the challenging curriculum ahead in optometry school. Managed by the Association of Schools and Colleges of Optometry (ASCO) and administered through the American Dental Association’s (ADA) testing services, the OAT is widely trusted as the benchmark exam for future optometrists.

At Study Alpha Academy, we help students understand the OAT inside and out—from exam content and scoring to effective preparation strategies.

What is the OAT Exam? [OAT Overview] The Optometry Admission Test (OAT) is an admissions requirement for most optometry schools in the United States and Canada. Like the MCAT for medical school or the DAT for dental school, the OAT serves as a standardized measurement of an applicant’s readiness for a professional degree program.

Why It Exists: Ensures candidates have the scientific foundations necessary for success.

Levels the playing field by providing a common benchmark across different universities and academic backgrounds.

Predicts a student’s ability to handle the rigor of optometry coursework.

OAT Exam Format and Structure [Sections Explained] The OAT consists of four main content sections, each assessing different skills:

1. Survey of Natural Sciences Content: 100 multiple-choice questions (Biology, General Chemistry, and Organic Chemistry)

Duration: 90 minutes

Skills Tested: Foundational natural science knowledge required for optometry education.

2. Reading Comprehension Content: 40 questions based on 3 long passages from scientific or medical-related topics

Duration: 50 minutes

Skills Tested: Analyzing dense text, making inferences, and evaluating arguments.

3. Physics Content: 40 multiple-choice questions

Topics Include: Mechanics, optics, electricity, thermodynamics, waves, and light.

Duration: 50 minutes

4. Quantitative Reasoning Content: 40 multiple-choice questions

Topics Include: Algebra, geometry, data analysis, probability, statistics, word problems.

Duration: 45 minutes

Exam Timing and Length Total Exam Time: Approximately 4 hours 50 minutes (including optional breaks).

👉 The comprehensive structure of the OAT means students need strength not just in science but also in reading skills, math, and physics problem-solving.

Why Take the OAT? [Importance of the OAT Exam] The OAT is essential for aspiring optometry students because:

Admissions Requirement – Most U.S. and Canadian optometry schools require the OAT as part of the admissions process along with GPA, recommendation letters, and interviews.

Predictor of Success – High OAT performance correlates with stronger success in optometry coursework.

Foundational Skills Test – Preparing for the OAT builds the science and reasoning skills needed for optometry school.

Competitive Advantage – Scoring well (e.g., 320+) boosts your profile and improves chances at competitive programs.

How is the OAT Scored? [Understanding OAT Results] The OAT uses a scaled scoring system:

Sections Scored: Each of the four sections receives a score.

**Score Range: 200 – 400 per section.

Average Score: ~300. ** Competitive Range: Many programs look for scores above 320, particularly at top-tier optometry schools.

👉 Scores are based on correct answers only, so there is no penalty for guessing. It’s always best to attempt every question.

Best Tips for OAT Preparation [OAT Prep Strategies] At Study Alpha Academy, we recommend the following strategies for OAT success:

1. Understand the Test Format Before diving in, familiarize yourself with the structure, timing, and question styles in each section.

2. Build Solid Science Foundations The majority of the OAT focuses on Biology, Chemistry, and Physics. Review course notes, and use targeted prep resources.

3. Practice Reading Scientific Content For the Reading Comprehension section, build analytic reading skills by practicing with dense scientific and academic passages.

4. Take Full-Length Practice Tests Simulate test day conditions to improve timing and endurance for the nearly 5-hour exam.

5. Strengthen Quantitative Reasoning Practice algebra, probability, and data analysis daily to improve speed and accuracy under time pressure.

  1. Create a Structured Study Schedule Dedicate 8–12 weeks of consistent prep. Break it into daily tasks that balance review, practice, and timed testing.

  2. Prioritize Health and Focus Eat well, exercise, and get proper sleep before and during preparation. A healthy body supports sharper test-day performance.

Frequently Asked Questions [OAT FAQs] Q: How many times can I take the OAT? Up to 3 times per calendar year, with a limit of 4 attempts in 12 months and 5 lifetime attempts.

Q: When should I take the OAT? Many students aim for the spring or summer before applying to optometry school, usually after completing key prerequisites like biology and chemistry.

Q: How long should I study for the OAT? On average, students prepare for 2–4 months, committing 15–25 hours per week.

Q: Is the OAT harder than the MCAT? While the MCAT covers broader content and passage-based reasoning, the OAT is highly science-focused and integrates physics, quantitative reasoning, and optics concepts important for optometry.

Q: Do all optometry schools require the OAT? Most in the U.S. and Canada do. Always check the admissions page of your target schools.
