I have been seeing more and more searches for this as of late and being that there is so much bad or incomplete information out there when searching for this I figured I would give everyone a thorough answer.

Let's take a look at a little bit of the history of the PMP^® exam, the PMBOK^® Guide, and the scoring of the exam.

The PMBOK^® Guide 2000 was first released on 12/1/2000, The PMP^® Exam was not based upon this release until 3/4/2002
At that time the PMI^® published passing score was 68.5% (137/200)

The PMBOK^® Guide 3rd Edition was first released on 10/31/2004, The PMP^® Exam was not based upon this release until 9/30/2005
At that time PMI^® had published that the passing score was changed to 80.6% (141/175)

Just 60 days later on 11/30/2005 PMI^® announced that they were changing the passing score from the new 80.6% to 60.6% (106/175) and that scoring model would be retroactive to those that took the exam since the first test date of 9/30/2005

In Early 2006 PMI^® announced that they would no longer be publishing passing scores, so nothing new has been published since the 11/30/2005 announcement.

On 10/1/2007 PMI^® announced that they would be changing the score reports produced upon completion of the exam. Just as before, there are two levels of information provided. One is the overall examination results, which will tell you whether you passed or failed. The other is a more diagnostic representation of your proficiency level per domain. Each domain or chapter is accompanied by one of three possible proficiency levels: Proficient, Moderately Proficient, and Below Proficient.

A commonly asked question when the change in score report came out was "Does the change in the score report indicate a different score or standard to pass the examination?"
The answer published by PMI^® was "No. People who take the examination will experience the same score standard as before. This means that people who receive the new score report are evaluated the same as those who received the old score report."

The PMBOK^® Guide 4th Edition was first released on 12/30/2008 and the PMP Exam will be switching over to this new edition after 6/30/2009.

So, given the information available one could draw the conclusion that the score needed to pass the PMP^® exam is still 60.6% (106/175) as it was when the last score requirement published by PMI^® on 11/30/2005. However, that would be making a huge assumption and we all know the saying about that. In simply looking at the facts, PMI^® stated in early 2006 that they would no longer be publishing passing score information. Yes, in October 2007 they stated that when the score reporting format was changed that the score requirement was to remain the same but that does not negate the possibility that they could have changed the passing score requirement sometime later.

In addition, it is PMI's recommendation that R.E.P.'s do not publish passing score data. Given our desire to comply with PMI^® recommendations we simply recommend trying to achieve at least 80% on any practice exams you may take.
