Nurse practitioners are registered nurses (RNs) who hold a master’s or doctoral degree in nursing, as well as a license from an approved national licensing body, such as the American Nurses Credentialing Center (ANCC) or the American Academy of Nurse Practitioners (AANP), and state licensing board. Certification is available for a variety of specialties and each licensing body has its own requirements, but they typically include the aforementioned post-graduate degree in nursing, a certain amount of nursing experience and a passing score on a certification examination. Individuals should check with their state boards of nursing to determine which certifications are accepted in their area, as the requirements for becoming licensed vary state by state.

The nurse practitioner’s scope of practice encompasses direct patient care, including diagnosing and treating illnesses. As stated, many nurse practitioners hold specialty licenses, specializing in areas such as acute care, adult care, pediatric care, gerontology and family nurse practitioner. Nurse practitioners also have varying degrees of prescriptive authority.

Nurse practitioners generally earn higher salaries and more generous benefit packages than those received by registered nurses. According to the U.S. Bureau of Labor Statistics, the average nurse practitioner salary in May 2016 was $104,610. Due to newly insured patients, aging populations and greater emphasis on preventative care,  the job outlook for nurse practitioners is better than ever. BLS projects that nurse practitioner employment will grow by 35 percent from 2014 to 2024.
