Is there a required Intern or residency period after CRNA school?

I am currently in a BSN program and I plan to persue either a master degree for an acute care NP or CRNA. I am trying to get as much information about each as possble, so I don't make the wrong choice. One question I have is whether or not you have to be a resident or Intern or both before officially having the CRNA title. Is it like doctors where you have a residency period where you make alot less money for years or is it like the RNs who finish school, pass boards, and only have a ouple months of orientation. Please help!!
