After completing the necessary education, aspiring nurses must pass a licensing examination to become a licensed nurse. For LPNs, this is the NCLEX-PN (National Council Licensure Examination for Practical Nurses). For RNs, it is the NCLEX-RN (National Council Licensure Examination for Registered Nurses). Both exams test the knowledge and skills necessary to perform safely and effectively as a newly licensed, entry-level nurse.
