If you are audited the first time, it’s highly likely that your next applications will be audited too. We sometimes hear from students who have had a second, third or fourth application rejected during the audit process.
You need to spend some time working out why your application was rejected. Then, if you still believe you do meet the eligibility requirements, you need to prepare your application again. Having someone read over your application form before you submit it might help, and talk to the audit team at PMI if you can.
Ultimately, you need to try to make your experience and education requirements match what PMI is looking for, in terminology that makes it easy for them to understand your achievements. It should go without saying that you cannot stretch the truth, exaggerate your involvement or embellish your achievements in any way. Your application must be completely honest. If your participation on a project doesn’t show what you are truly capable of, can you use a different project where you were actively leading and managing the work instead?
Check the Handbook for details about when you can apply again.
Note: If you were declined for lying on your application, then you can’t apply again for any of PMI’s certifications. Ever.
