The NACNS reports that clinical nurse specialists are educated and trained to partner with other providers in the leadership role for the coordination of care and care transitions. The coordination of care and promoting a seamless care transition, is often identified as being integral to the CNS role.

Education Requirements

Clinical nurse specialists are registered nurses (RNs) and graduate-prepared APRNs. The typical route to becoming a clinical nurse specialist involves earning an RN through a pre-licensure program (nursing diploma, Associate Degree in Nursing (ADN), or baccalaureate degree), earning valuable experience as an RN, and then achieving a Bachelor of Science in Nursing (BSN) and Master of Science in Nursing (MSN).

Because the majority of RNs complete a pre-licensure nursing diploma or ADN, enrolling in RN to MSN programs, which allow students to earn both a BSN and MSN at an accelerated pace, has become a popular option for RNs looking to become clinical nurse specialists. RN to MSN programs take into consideration the experience and pre-licensure education of an RN, thereby allowing students to transfer a large number of their undergraduate requirements and completing both their BSN and MSN in just 2 to 3 years.

Many of today’s RN to MSN programs are available as distance learning programs, allowing students to complete their didactic coursework through online study. This type of curricula delivery accommodates the busy schedules of today’s working student. Both online institutions and campus-based institutions offer this type of online learning experience.

Clinical nurse specialist programs may feature different specialty tracks, which require the completion of specific specialty courses. For example, one RN to MSN program may be focused on acute care, while another may be focused on oncology or gerontology. However, core courses in a CNS program are generally similar, as they include:

  • Epidemiology
  • Nursing concepts and theories
  • Ethics for health professionals
  • Research for health professionals
  • Advanced health assessment
  • Advanced pharmacology
  • Advanced physiology/pathophysiology
  • Health policy issues
  • Health care financing

Certification Requirements

Upon completion of a CNS graduate program, graduates must achieve national certification through a national certifying body recognized by their state board of nursing.

The following certifying bodies offer national certification examinations for clinical nurse specialists, although not all state boards of nursing recognize all national certifying bodies/certifications:



  • American Nurses Credentialing Center
    • Adult health clinical nurse specialist
    • Adult psychiatric and mental health clinical nurse specialist
    • Child/adolescent psychiatric and mental health clinical nurse specialist
    • Gerontological clinical nurse specialist
    • Pediatric clinical nurse specialist
    • Home health clinical nurse specialist
    • Diabetes management – advanced

Once national certification through a recognized certifying body and in a recognized CNS certification area has been achieved, candidates must apply for state certification through their state board of nursing. All states require candidates to possess a current and unencumbered RN license and national certification to achieve state certification as a CNS.

Like the RN license, clinical nurse specialists must renew their national certification designation by meeting continuing education requirements.

Salary Expectations for Clinical Nurse Specialists

According to the NACNS, clinical nurse specialists generally earn between $65,000 and $110,000 per year, depending on the region of the country in which they practice and their CNS practice specialty.

The clinical nurse specialist job earned a spot on CNN Money’s Best Jobs in America in 2013 list, with the news agency reporting a median salary of $86,500 and a top salary of $126,000 for clinical nurse specialists.
