Potential employers may prefer a candidate with experience as a CNA, but it’s not necessarily a requirement for getting a job as an LPN (same goes for going from CNA to RN).
You aren't required to go from CNA to LPN and there is no prerequisite to be a CNA before enrolling in the Herzing University PN program.
