The Otis-Lennon School Ability Test, or the OLSAT, is an exam that is given in kindergarten through 12th grade in order to determine the logical reasoning ability of students. It contains both verbal and nonverbal questions. The verbal questions consist of categories such as sentence completion and logic. The nonverbal questions have categories such as picture analogies, the classification of different figures and number series. In order to interpret the Otis-Lennon School Ability Test, understand the test that is associated for each grade level, determine which types of questions will be on that exam, review information from class that is on the exam, take practice tests and evaluate your score on the actual exam.

Understand the test that is associated with each grade level. There are seven different test levels for the Otis-Lennon School Ability Test. Level A is for kindergarten; level B is for first grade; level C is for second grade; level D is for third grade; level E is for fourth and fifth grades; level F is for sixth, seventh and eighth grades; and level G is for ninth, tenth, eleventh and twelfth grades. Therefore, if you are in third grade, you will take the level D exam.

Determine which types of questions will be on the exam. Each level has different categories of verbal and nonverbal questions. It is important to know which information will be on the exam that you are taking. Online, at the Pearson Assessments website, you can find a chart that has each test level and the material that is on all of those exams. There is a black dot for each category that will be on the test. For example, number series will be on the level D exam because there is a black dot in that row.

Review information from class that is covered on the exam. When interpreting the OLSAT exam, relate the subjects that you learned in school to the subjects that will be on the test. For example, since number series will be on the test, study the portion of your math notes that relate to number series.

Take practice OLSAT tests. To interpret OLSAT tests, become familiar with the types of questions on the exam. The questions on the OLSAT test are multiple choice and consist of five possible answer choices. After you take the practice test, correct yourself and try to understand your mistakes. Resolving an error on the practice exam will help you to better interpret the questions on the actual exam.

Evaluate your score when you take the actual OLSAT exam. After you take the exam, your results will be sent to you. The results are expressed in percentiles that compare your performance to that of other students that have taken the same exam. The higher your ranking, the more proficient you are at logical reasoning compared to the other students.
