I think it took about 1 week for my work experience to be reviewed. It also depends on how fast your supervisor responds to the email confirming your experience.
Edit: I'm in NC, I don't know if that makes a difference through NCEES though.
I submitted mine April 30th..... Still waiting. I received an email shortly after submitting saying that my application was administratively complete and ready for board review, but still no word on the boards decision. I called them last week and they told me that there is not an official board...
I just wanted to introduce myself and say hi to everyone. I am an certified EIT patiently awaiting approval from the board on my North Carolina PE license. Its a brutal wait. How long did it take your state to approve your license once you submitted all your paperwork?
