What is a Public Health Nurse?

The American Public Health Association (APHA) defines public health nursing as "the practice of promoting and protecting the health of populations using knowledge from nursing, social, and public health sciences" (2013).

Following this definition, PHNs work to promote and protect community health by collaborating with healthcare teams to deliver healthcare education and disease prevention to groups. Instead of treating acute health conditions, they focus on long-term health, safety, disease prevention, and improving a community's access to care.

PHN Patient Populations

Public health nurses often serve underprivileged populations in the US and around the world. They deliver education and care to at-risk populations and are particularly active during public health crises. Some examples of groups PHNs work with include unhoused people, the elderly, or immigrant communities.

How to Become A Public Health Nurse

Like other nursing specialties, the first step to becoming a PHN is earning your registered nursing license. Then, you'll gain relevant working experience and earn a public health nursing certification.

Step 1. Attend an Accredited Nursing Program

You can attend a 2-year Associate Degree in Nursing (ADN) or a 4-year Bachelor of Science in Nursing (BSN) degree to become an RN.

While both degrees qualify you to take the NCLEX-RN exam, the public health nurse certification requires a BSN. So, you may start with an ADN, but you need to work up to your bachelor's before earning your PHN credentials.

Step 2. Pass the NCLEX-RN Examination

After graduating from nursing school, you must pass the NCLEX-RN exam to become a licensed registered nurse. This test assesses whether you have the clinical knowledge, critical thinking skills, and abilities needed to become an entry-level nurse.

Step 3. Gain Experience

While not necessary for many entry-level PHN jobs, bedside experience has undeniable benefits. For example, working as a staff nurse can help guide your career decisions, leading you toward public health or a specialty more suited to your interests. 

Additionally, bedside experience can help you land better public health nursing jobs. Not only will it increase your confidence, but it will also fill your resume with impressive, relevant accomplishments that give you a competitive edge. 

Step 4. Earn a Public Health Nursing Certification

Like other public health professionals, PHNs can earn the Certified Public Health credential. While not specific to nursing, this certification showcases your knowledge and skills in the public health sciences. Earning and maintaining this credential signifies your dedication to excellence in the field.

Eligibility requirements for the CPH include:

  • A bachelor's degree in any concentration and at least five years of experience working in public health OR

  • A relevant graduate degree and three years of experience working in public health OR

  • A graduate-level public health certificate from a CEPH-accredited or applicant school and three years of experience working in public health

The computer-based exam costs $385, and retakes cost $150. The exam consists of 200 multiple-choice questions, which you'll have four hours to complete.
