LVN vs. LPN: What Is The Difference Between LVN and LPN? Here is what is meant by LVN vs. LPN: licensed practical nurse (LPN) can also be called a licensed vocational nurse (LVN). As such, there is no essential difference other than in grammatical terms. It is possible for someone to enter the health industry as a LVN or a LPN. In certain states of America you would be known by either of the names, however, the role that you perform will be the same.
The major difference between LPN and LVN is the name and the geographical location where one term is used in favor of the other. In California and Texas, the state nurse licensing board refers to the position as licensed vocational nurse. In all other states, the position is called licensed practical nurse. For example, if an LVN in California or Texas moves to another state, the new licensing of the state will refer to the same person as an LPN. An LPN who moves to and becomes licensed in California or Texas will be referred to as an LVN. LPNs and LVNs perform essentially the same duties in all states.
