Hi Michael, it should be alright to provide one reference if they can attest to your entire experience. But if you are doing this, please make sure you speak with your reference ahead of time and verify that their information (email, contact number, etc.) are all updated correctly. You want to avoid submitting incorrect information especially when you are dependent on only one reference.

Micheal,

A single reference for each of those projects is fine as long as they can vouch you did all of that work. Ultimately, it is up to you as to who you find trustworthy and can reliably vouch for each project you've done. If you get audited, they will send a sealed envelope to that person and have them affirm that they are reliable and that they confirm you performed those projects. If they don't back you up, you could be barred from testing or applying for a significant amount of time.

Hello, I wanted to apply for PMP and started the Udemy course. I wanted to put a reference and was wondering how many references I need to provide for my projects? I worked for 10 years in a company. Is it okay to provide only 1 person? Thanks
