Everyone that holds a project management credential from the US-based Project Management Institute must earn Professional Development Units, i.e., “PDUs”, to maintain those certifications. You do not want to take these professional exams twice!
PDUs are self-reported through one’s account at www.pmi.org, and PMI awards 1 PDU for every 1 hour spent doing, learning about, and promoting the profession of project management.
You can earn PDUs easily, for free, and enjoyably by listening to and watching Vets2PM’s PM Pathfinder Series of podcast episodes.
