The National Council Licensure Examination (NCLEX) is the nationally accepted examination for nurse licensure in the United States as well as Canada. There are two types- the NCLEX-RN and the NCLEX-PN. After graduating from a certified nursing school, he or she will need to take the appropriate NCLEX in order to receive a nursing license. The NCLEX-RN is for those intending to be a registered nurse, while the NCLEX-PN is for those intending to be a vocational or practical nurse.
