Steps to Become a Public Health Nurse 

There are several steps to become a public health nurse. Students usually start by pursuing a nursing degree, and move on into a public health nursing specialty. 

Here are common steps to become a public health nurse.

Step 1. Attend an accredited nursing program

Students should seek out a program accredited by the Accreditation Commission for Education in Nursing (ACEN) or the Commission on Collegiate Nursing Education (CCNE). Attending an accredited nursing program allows students to:

  • Attend a graduate nursing program
  • Compete in the job market 
  • Receive federal financial aid
  • Transfer credits to the program

 Degrees to pursue a career as a public health nurse include an Associate Degree of Nursing (ADN) or a Bachelor of Science in Nursing (BSN). 

Step 2. Study and pass the NCLEX-RN exam

The National Council Licensure Exam-Registered Nurse (NCLEX-RN), developed by the National Council of State Boards of Nursing, is a standardized exam that tests you on the practical application and analysis of everything you’ve learned at nursing school. It helps determine whether you have the knowledge and skills to work in the field of nursing.

Step 3. Gain experience in nursing

After getting a license, it is recommended that nurses gain at least two years of experience before beginning the process of becoming a public health nurse. 

Step 4. Obtain certification as a certified public health nurse

There is one general public health nurse certification for nurses just obtaining licensure. The Certified in Public Health designation is available through the National Board of Public Health Examiners.

To be eligible for a CPH, these criteria must be met:

  • Student of a school or program of public health accredited by the Council on Education for Public Health (CEPH)
  • Alumni of a school or program of public health accredited by CEPH
  • Public health work experience, including: 
    • A bachelor’s degree, in any concentration, and at least five years’ public health work experience OR
    • A relevant graduate degree, and at least three years’ public health work experience OR
    • A certificate from a program or school of public health accredited by or in applicant status with CEPH, and at least three years’ public health work experience.

Step 5. Get continuing education and training

Continuing education and training are recommended for all public health nurses. This ensures that nurses are well-versed in new studies, innovation and ideas within healthcare and public health. This is also a good way for nurses to open up new career opportunities.

All nurses with a CPH certification must report at least 50 recertification credits every two years. Extensions are available in three-month increments.

Another way to gain more knowledge is with a Master of Public Health-Master of Science in Nursing dual degree. Find out more about obtaining an MPH-MSN degree.

Where Do Public Health Nurses Work? 

Because public health nurses focus more on entire communities than individuals, they work in a variety of public settings. Here are five places public health nurses might work and their responsibilities:

Community Clinics

Public health nurses work closely with the community in clinics, dealing with a variety of health concerns. Because of these experiences, they will be on the front line in developing educational programs to teach the community how to improve overall health. This advice can be individual-based or community-based. 

Government Organizations

County, state or national health departments rely on public health nurses. They will focus on policy development to improve the overall health of entire populations. These positions often focus on administration and paperwork and less on individual patients.

Outpatient Clinics

People often go to outpatient clinics with health concerns. While public health nurses can address their immediate concerns, send out for tests and perhaps even prescribe medication, they can also take a leadership role in public health education. 


Public health nurses will help children and their parents address issues in schools. They will help educate children how to maintain their own health and prevent illness, plus address personal hygiene, sexual health and other issues. These nurses will also monitor at-risk children, watching for signs of abuse or neglect.

Voluntary Organizations

Numerous organizations help deliver health solutions to those in need with the aid of public health nurses. These groups include Doctors Without Borders, the Peace Corps and the Red Cross. Among the duties of public health nurses are disaster relief, drinking water safety, education, family planning, hygiene, sexual health and more.

Public Health Specialist vs. Public Health Nurse

Learn about the differences between a public health specialist and a public health nurse.

Public health nurses can perform many of the job functions of public health specialists. Perhaps the biggest difference is that nurses have the educational background and clinical experience to be able to provide care to patients. Public health nurses may focus on treating a group of people, whereas other types of nurses treat individuals.

Some entry-level public health nursing roles may only require a BSN, but those who want to become a public health nurse must be registered nurses. Given the leadership that is often required in this position, having an MSN is recommended.

Public health specialists are focused on improving health outcomes through research, education and prevention. This can include areas such as environmental health, disease etiology, occupational health, nutrition and more.

A public health specialist may have these job responsibilities, depending on their role:

  • Organize and implement research studies to improve public health outcomes.
  • Study and report on disease patterns and infection data.
  • Analyze data using applied statistical and qualitative methods.
  • Provide feedback to organizations seeking to improve employee health and safety.
  • Communicate research findings to clinicians and stakeholders.
  • Design, implement and manage public health programs.

While a public health specialist may design and develop interventions, a public health nurse may help to carry out the interventions, especially if they involve administering care.
