What Is a PDU in Project Management?
A PDU, or Professional Development Unit, is a unit used to measure ongoing development within the field of project management.
To maintain certification as a Project Management Professional (PMP), you will need to maintain a specific number of PDUs, earned by attending events or accomplishing courses. 60 PDUs are required over three years.
How to earn PDUs
- Ongoing education: Take in-person or online courses, attend seminars, webinars, and industry events, or get into self-directed learning and take it at your own pace. Just make sure the course you're taking is officially sanctioned to give out PDUs.
- Give back to the industry: Create content that can be added to the body of knowledge, volunteer to provide your project management services outside of your company, or simply do your job (practicing project management daily counts toward your credentials). More details are on the Project Management Institute (PMI) page.

Milestones help break projects into manageable phases, guide decision-making, and keep stakeholders informed of critical achievements.
