### ORELA Middle Grades Math: Exponents & Exponential Expressions Chapter Objectives

To pass the ORELA Middle Grades Mathematics test you will need to score 225 or higher on the scaled score system ranging from 100-300. The primary content domain where these types of questions will fall is the Number Sense and Operations domain, which is 17% of the whole and evaluates competencies 0001 and 0002. You certainly can expect to see problems involving all sorts of exponents throughout the exam, however, so this will be useful practice for the entire test. The lessons in this chapter are built to help you fly through exponential expressions during the exam.

This test is one of the available subject-matter exams as part of the Oregon educator's licensure process. You will have four hours and 15 minutes to complete the 150 multiple-choice questions, completed entirely on computer. The computer will have an on-screen calculator to help you solve more complicated problems. It will take about two weeks to receive the NES score report and the Oregon score report, but you will get your scaled score immediately after the test.
