The compact does not cover APRN roles
The Nurse Licensure Compact covers RN and LPN/LVN licenses. It does not cover APRN authorization — NPs, CRNAs, CNSs, and CNMs. That has been the case since the compact began and applies in every state.
What that means in Tennessee
Tennessee is a compact state, so your underlying RN license can be a multistate license. But your APRN authority sits on top of that RN license and is not part of the compact — to practice as an APRN in another state, you generally need that state’s APRN authorization, granted by its board. Confirm specifics with the Tennessee Board of Nursing.
The separate APRN Compact
A distinct APRN Compact has been drafted to do for advanced practice what the NLC does for RNs and LPNs/LVNs, but it is not yet operational. Until enough states join and it is implemented, APRN privileges do not cross state lines automatically.
