Types of Nurse Practitioners – What Kinds of NPs are There?

The two-year path to becoming a nurse practitioner (NP) is the same for everyone: earn an accredited master’s degree (or higher), get a state license, and pass a national certification exam. However, at the degree and certification stages, NPs can choose to specialize in a specific area to provide care to general and niche patient populations.  

Most nurse practitioners start with a general certification in primary care. In addition, most nurse practitioner certifications focus on primary care for families, adults, and older adults, with nearly 88 percent of NPs holding at least one of these certifications. As proof of point, in 2021, the American Nurses Credentialing Center (ANCC) awarded 277,550 certifications for nurse practitioners in primary, acute, specialty, and psychiatric-mental health. 

Other organizations offer more specialized certifications, such as the American Association of Critical-Care Nurses (AACN), which has more than 130,000 members and offers four nurse practitioner certifications for neonatal, pediatric, adult, and gerontological patients.

The good news is that NPs need not limit themselves to only one certification. NPs can earn multiple certifications from different professional organizations to serve a wide range of patient populations and increase job prospects. Eligibility requirements vary but typically include several clinical hours in a specific patient area. One can earn these hours during or after completing a master of science in nursing (MSN) degree, a doctorate of nursing practice (DNP), or a post-master’s certificate program.

The American Association of Nurse Practitioners (AANP) is the largest professional organization for nurse practitioners. The AANP includes more than 355,000 advanced practice registered nurses (APRNs) members. The AANP, as an umbrella organization, recognizes five certification boards:

  • American Academy of Nurse Practitioners Certification Board (AANPCB)
  • American Nurses Credentialing Center (ANCC)
  • American Association of Critical-Care Nurses (AACN)
  • Pediatric Nursing Certification Board (PNCB)
  • National Certification Corporation (NCC)
