In this course, you will find eight lessons that will assist you in recognizing common signs and symptoms of substance and non-substance performance inhibitors. At the end of each lesson, you must complete the short quiz before you can move to the next lesson.

After you have successfully completed all eight lessons and all eight-lesson quizzes, you will be able to download and print a certificate of completion. Print a copy for your records and print a copy to give to your supervisor or the designated representative in your organization.
