The Human Resource Management DSST isn’t particularly difficult if you’ve worked in a corporate environment. The new hire orientation that most employees go through covers much of the material on this exam and serves as a good introduction. If you’ve ever held a management position, you’ll likely already be familiar with many of the topics. However, the Employment Law section and the part on Organized Labor (Unions) tend to trip people up. If you haven’t had any direct experience with those subjects, be sure to spend some extra time studying them. Don’t overlook the HRM overview section either—it’s foundational and worth your attention. I’ve included some free resources below that offer a brief look at how human resources has evolved over time. My test center proctor recommended taking the two management exams first—Principles of Management CLEP and Principles of Supervision DSST—and I agree. Not only are they easier than the HRM exam, which can give you a confidence boost, but they also cover some of the same material and will help you prepare more effectively. Likewise, once you take this one, the Business Ethics and Society will be a bit easier thanks to the overlap of employer/employee law and relationships.
