The OTR® Content Test in Mental Health consists of 35 questions. The intent of the practice exam is to give you experience with taking an online exam, the format of the questions, and the type of content you’ll see on the certification/licensing exam. You will have 90 minutes to complete the test. You cannot reenter this test once you have submitted it for scoring. Your score on the practice exam is NOT predictive of your score on the certification/licensing exam.
