Hi Kila,
Referring to PMI PMP handbook on page 6, to apply for PMP certification you will need a minimum of 36 weeks and at least 4500 hours of non-lapping professional project management experience leading and directing the project in all 5 process groups (initiating, planning, executing, monitoring and controlling, closing). If you have all the above-mentioned, you are eligible. You may want to download the handbook from PMI website at
www.pmi.org/certifications/types/project-management-pmp
to check your eligibility. The handbook also show you how to record your experience on the application (see page eight). Most importantly, bear in mind that in the event that you are randomly selected for audit, you will have to provide supporting documentation (see page 14). Hope this helps!
