The requirements for renewing a nursing license vary depending on the state in which the license is issued. In most states, licenses must be renewed every two to five years, according to information compiled by Lippincott's NursingCenter.com.
Renewal requirements for nursing usually require a certain number of contact hours with patients during the previous licensing period, but the exact number varies by state, reports Lippincott's NursingCenter.com. Some states also have additional requirements, such as a nursing refresher course or satisfactory job reviews from a former employer. The nursing boards for individual states have the most complete list of license renewal requirements for nurses in their regions.
