The NLC was created by the National Council of State Boards of Nursing (NCSBN) and is an interstate agreement implemented in 2000. In 2018, the NLC was updated and is known as the enhanced NLC or eNLC. This interstate agreement enables registered nurses (RNs), licensed practical nurses (LPNs), and licensed vocational nurses (LVNs) who meet NLC requirements to practice in states that have implemented the NLC.
