Nurse Practitioner Credentials: What Do All of Those Titles & Letters Mean?

Becoming a nurse practitioner may feel like eating a bowl of alphabet soup. With so many degrees and titles represented by all-caps acronyms, people wonder: what do all these letters mean? Understanding the nursing profession requires some familiarity with nursing degrees, specializations, certifications, and professional organizations, all represented by acronyms. 

This jargon aims not to confuse people but to make short work of lengthy titles and accurately display credentials. This guide decodes common nurse practitioner (NP) credentials, including the display order, designations, degree and certification programs, specializations, and fellowship award titles.

How to Display Nurse Practitioner Credentials – The Proper Order

Nursing titles aren’t to be thrown about – there are rules on how to display them correctly. For example, Indeed.com provides guidelines for displaying nursing credentials (see examples in parentheses):

  • Highest-earned degree (e.g., MSN, DNP)
  • Licensure (e.g., LPN, LVN, RN)
  • State designations or requirements (e.g. APRN, NP, CNS, CNA, CNM)
  • National certifications (e.g., FNP-BC, PMHNP-BC)
  • Awards and honors (e.g., FAAN or Fellow of the American Academy of Nursing)
  • Other recognitions (e.g., EMT, cardiopulmonary resuscitation [CPR], basic life support [BLS], or advanced cardiac life support [ACLS])

The principle behind these guidelines is this: permanent credentials come first, and more voluntary credentials are last. For example, if a family nurse practitioner has an MSN, state licensure, and board certification, their title would be Janice Doe, MSN, APRN, FNP-BC.

For legal purposes, nurse practitioners need only display the APRN credential next to their names when writing, prescribing, or presenting. For example, if a nurse practitioner is authoring a research paper, presenting at a conference, or providing legal testimony, they should address themselves as Janice Doe, APRN.

All nurse practitioners have advanced degrees, but those with two advanced degrees need only display their highest level of education. Also, if an NP has a master’s or doctoral in a non-nursing field, those degrees are listed first. For example, suppose a family nurse practitioner has a master’s of public health (MPH), a master’s of science in nursing (MSN), a doctorate of nursing practice (DNP), and board certification. In that case, the ANCC recommends they write their title in this order: Janice Doe, MPH, DNP, APRN, FNP-BC (note the MSN is omitted).

NP Degree Abbreviations

All nurse practitioners have a minimum of a master’s of science in nursing (MSN) degree, and some have a doctor of nursing practice (DNP). However, many MSN and DNP degree programs are advertised with the level of education an applicant has and the final conferred degree. For example, a BSN-to-MSN program requires applicants to have a bachelor of science in nursing, which results in an MSN degree. 

When searching for NP degree programs, knowing all the degree abbreviations in the nursing field is helpful. Here’s a list of degree abbreviations, listed from lowest to highest levels of education, and a general time-to-completion.

LPN: Licensed Practical Nurse

DNP: Doctor of Nursing PracticeTwo to six years

NP Awards Fellowships

Earning an award is a high honor for any professional and nurse practitioners are no exception. Awards can be very high-profile and worthy of inclusion in a professional title. Here are three examples of awards and fellowships that nurse practitioners can earn. 

The American Academy of Nursing (AAN) honors 2,900 Fellows who are nursing leaders in education, management, practice, and research. NPs with this award can use the FAAN designation in their title. 

The Society of Hospital Medicine offers three levels of awards to physicians, healthcare administrators, nurse practitioners, and physician associates:  

  • Fellow in Hospital Medicine (FHM)
  • Senior Fellow in Hospital Medicine (SFHM)
  • Master in Hospital Medicine (MHM)

Clinical healthcare professionals can use these designations in their titles if awarded. 

The American Association of Nurse Practitioners (AANP) awards Fellows through the Fellows of the American Association of Nurse Practitioners (FAANP). Award winners can display the FAANP credential should they be nominated for and receive this award. For example, the 2022 winner’s name and designations were: William E. Rosa, PhD, MBE, AGPCNP-BC, FAANP, FAAN.
