The criteria for the PMP Exam has gotten far more specific than it was in the past. You must have a BA/BS degree or the global equivalent of a 4-year degree, 35 hours of project management education, and 4,500 (non-overlapping) hours leading and directing projects. PMI has also done a role delineation study that shows exactly what leading and directing projects means:
Candidates perform their duties under general supervision and are responsible for the project for the life of the project.
Candidates lead and direct cross functional teams to deliver projects within the constraints of schedule, budget, and scope.
Candidates demonstrate sufficient knowledge and expertise to appropriately apply a methodology to projects that have reasonably wekk-defined requirements and deliverables.
So if you meet these criteria, you are eligible to sit for and will have a good chance at passing the PMP exam.
