At that time the name of the test was changed to the Optometry Admission Test (OATTM) .  \nThe Optometry Admission Test (OAT) is administered under the auspices of the Association of Schools and Colleges of Optometry (ASCO) for applicants seeking admission to schools and colleges of optometry. This testing program is designed to measure general academic ability and comprehension of scientific information. While the majority of optometry schools in the United States and Canada require applicants to participate in the OAT Program, test results are only one factor considered in evaluating an applicant’s potential.  \nValidity studies conducted by the testing program have shown that test scores in , conjunction with collegiate records, are quite useful in predicting optometry school performance. The relative importance of these predictors in the admissions decision-making process is determined separately by each optometry school.  \nContent of the Optometry Admission Test  \nThe OAT is a battery consisting of four individual tests: the Survey of the Natural Sciences, Reading Comprehension Test, Physics Test, and Quantitative Reasoning Test.  \nThe Survey of the Natural Sciences is an achievement test covering content from first-year courses in Biology, General Chemistry, and Organic Chemistry. The 90-minute test contains a total of 100 items, including 40 Biology items, 30 General Chemistry items, and 30 Organic Chemistry items. The three subtests are subdivided into several topic areas.  \nThe Reading Comprehension Test consists of 50 items and three reading passages of approximately 1,000 to 1,500 words each. The subject matter of these passages is drawn from aspects of the basic sciences. Each passage is followed by approximately 15 to 20 items that examine the concepts and ideas developed in the passage. The time limit for the test is 60 minutes.  \nTh","cbCaivhJku8VT8gf","https://ap.wps.com/l/cbCaivhJku8VT8gf","pdf",597178,32,"English","# Part One: Introduction and Background\n## History of the Optometry Admission Test (OAT) Program\n## Content of the OAT\n## Test Construction\n## Interpreting OAT Scores\n## Evaluation of the OAT Program\n## Introduction to the Tables\n## References\n# Part Two: 2025 Data Tables\n## Table 1.
