Every month I get a copy of PMI Today and I annotate 3 data points: New PMP® for the month, new PMPs year-to-date (YTD), and total number of active PMPs.
This month was a little interesting because PMI stopped reporting the New PMP monthly numbers and the YTD total, opting to report just the overall number of active credential holders. This is not a problem since I have been tracking the PMP data for over a year.
The trend continues, with the new number of PMPs in May totaling 3,985. Year-To-Date total is 23,581. There are a total of 385,096 active PMPs.
The current trend predicts PMI will hit 400,000 active PMP credential holders this year.
| December (2009) | January | February | March | April | May | |
| New PMPs (Monthly) | 5,403 | 3,714 | 3,713 | 5,344 | 4,718 | 3,985 |
| New PMPs (YTD) | 3,714 | 7,429 | 12,779 | 19,596 | 23,581 | |
| Total Active PMPs | 361,238 | 367,619 | 371,014 | 375,959 | 381,111 | 385,096 |
Though I'm still worried we're rapidly reaching a tipping point, I want to congratulate those 3,985 out there who passed the exam. It's no cakewalk and I recognize your efforts and achievement.
Of those 3,985, I've been in contact with several who passed the exam with the aid of my new product PMPrepFlashcards.com. Yes, I know, gratuitous plug.
The new data PMI did include in this months PMI Today was very enlightening. It's about the other credentials. 
As of May 2010, there were 385,096 active PMP credential holders. In comparison, there were only 11,458 Certified Associates in Project Management (CAPMs)®, 421 Program Management Professionals (PgMPs)®, 357 PMI Risk Management Professionals (PMI-RMPs)®, and 320 PMI Scheduling Professionals (PMI-SPs)®.
With the industry dominance of the PMP® credential, it makes me question if these other certifications have the staying power. Is there a demand for them or are they just a possible revenue stream for PMI? Will there other certifications for the other knowledge areas? Is Certified Scope Professional and Certified Communications Professional not far behind? If I would PMI, I would go for it. You don't know what the market will find valuable unless you try it.
