Education. The only way to become a nurse practitioner involves earning a master's degree in nursing or higher. Students need to have a bachelor's degree prior to applying to a Master of Science in Nursing (MSN) program. Although individuals with a bachelor's degree in another field may apply, a BSN is the recommended background.
