### NES Math: Exponential & Logarithmic Functions Objectives

Five states require passing the NES Math test as a condition for certification to teach the subject at the secondary level. The test is administered by computer, and all its questions are multiple-choice. Because our lesson quizzes and the chapter exam are also computer-based multiple-choice tests, they can familiarize you with what you'll encounter on test day in addition to assessing your knowledge.
