It is my understanding you need all areas to make it through the application process.
See enclosed chart.

I have a question regarding my application for PmP certification. I am a project coordinator I have worked in A LOT of projects in the past 4 years, would my application be denied if I wrote my hours per project were only in 3 out of the 5 PM process groups? "Executing, Monitoring & controlling, and Closing" or do I need to have hours in all of them? Because this would be not in my domain of work specially at Initiating or Planning.
