I love how all these websites are touting the PMP certification as a hot certification to obtain for IT right now. You cannot just wake up one day and say "I want to be PMP certified in the next 6 months" there are strict requirements you have to meet in order to even sit for the test. If you have a bachelor's degree, you still need to have 3 years of project management experience with 4,500 hours of qualifying activity and 35 hours of PDUs. If this is an activity you are not involved in currently, it takes quite a bit of commitment from your organization to get you qualified. The best site I found for the path to certification is the following;

I will say it might be worth obtaining the CompTIA Project+ certification before looking to go this route. The test (currently) does not expire, there are no requirements to test, and it will show your employer you are serious about the PMP path. When I did the test, I think the all study material and the test came in under $400.00.

Just my two cents...
