Maintain & Renew Your Certification
Maintaining your certification means investing in your professional development. That’s why professional development units (PDUs) are required to maintain every PMI certification. They help drive better business outcomes and develop in-demand skills, while helping you maintain your certification status. PDUs are one-hour blocks of time you spend enriching your certification through educational resources and giving back to the project profession.
Make the most out of your maintenance with these PMI tips:
- Understand the PDU requirements for your specific certification (requirements differ)
- Choose ways of earning PDU hours that pique your interest
- Log your PDUs in the Continuing Certification Requirements System (CCRS)
- Or, get the PMI Official mobile app, your one-stop source for tracking your certifications
