The Optometry Admission Test (OAT) is administered by the Association of Schools and Colleges of Optometry (ASCO) to assess a graduate student's readiness for academic work required in optometry school. It is used by optometry school admissions departments to compare students by using a single, standardized test. The OAT focuses on academic ability and scientific comprehension.
The OAT is offered throughout the year and is scheduled with Prometric testing centers. Students should contact the nearest testing center for available dates.
The OAT is 3 hours and 55 minutes long.
The OAT costs $435. Low-income students can request a fee-waiver which reduces test fees by 50%.
Before you register for the test, you'll need a Personal Identification Number (PIN).
What Is On the OAT
The OAT consists of four sections: Survey of the Natural Sciences, Reading Comprehension, Physics, and Quantitative Reasoning. Each section is timed. You'll have 90 minutes to complete the Survey of the Natural Sciences section, 50 minutes each for Reading Comprehension and Physics, and 45 minutes for Quantitative Reasoning.
How the OAT is Scored
The OAT is scored on a 200-400 point scoring system. The OAT only scores correct answers. There are no penalties for incorrect answers so it is best to guess if you are unsure of an answer.
Retaking the OAT
Many students retake the OAT to improve their scores; however, students may not choose which scores to send to optometry schools. The score report will include the four most recent scores.
