Answer keys for self-check quizzes, free-response questions (FRQs) and more are located in an appendix of the Instructor Guide associated with the course.
In most cases, you will find the questions and the answer keys in Appendix A of the Instructor Guide. Appendices are separate folders containing multiple documents. Please check the primary Instructor Guide document for a Table of Contents, which will explain where to find the answer keys and many other resources.
Members can download the Instructor Guide bundles by logging in at http://NROCNetwork.org and selecting the course from the "Courses" menu. Look for the "Instructors" tab. If you do not have secure access to the NROC Network, ask your project manager to tell you who does. Most often, your project manager or LMS administrator will have access to download resources for instructors.
