I understand your surprise; many people only notice at the very end that renewal isn’t automatic once the 60 PDUs are completed. The reality is: yes, it’s worth renewing. If you let it lapse,
you’d have to go through the exam process again, and nobody wants that. The renewal fee is small compared to the time, cost and effort it took to earn the certification.
And if you’re a PMI member, the benefits and discounts usually pay off by themselves. I always tell my students and clients that the PMP is more than a paper, it’s a signal of commitment.
Keeping it active saves you a much bigger headache later. So yes, press that button.
