Earning a certification in public health demonstrates a professional’s dedication to meeting and maintaining national standards, adhering to professional values, and following a core body of knowledge. To sit for the exam, a candidate must meet one of the following criteria:

The National Commission for Health Education Credentialing (NCHEC) designed the CHES exam for health education professionals in the early stages of their careers.

  • Planning health education
  • Implementing health education
  • Conducting evaluation and research related to health education
  • Administering and managing health education
  • Serving as a health education resource person
  • Communicating, promoting, and advocating for health and the health education/promotion profession

To sit for the exam, an applicant must hold a bachelor’s degree with at least 25 credits specific to the seven key areas. Exam fees range from $220-$370 depending on student status and registration deadline.

Master Certified Health Education Specialist

The MCHES exam emphasizes public health leadership skills, such as identifying staff development training needs, developing and managing budgets, and creating strategic plans.

To qualify for the exam, a CHES-certified professional should possess at least five years of active certification. Professionals without CHES certification can qualify if they hold a master’s degree in a relevant discipline in addition to five years of experience as a health education specialist.

Exam fees range from $285-$435, depending on registration deadline.

Obtaining the PHA requires at least a bachelor’s degree and three years of administrative and supervisory experience in the public or private health sector. Each applicant must also provide evidence of fulfilling the five professional competencies through previous education or work experience.

Exam fees range from $150-$195, depending on membership and certification status.


What is the difference between a certificate and a certification?

A certificate is a document proving completion of academic or vocational education. It is conferred by an educational program. Certifications, delivered by independent organizations, provide professional credentials earned through experience and/or examination.

Do I need to renew my certifications in public health?

Typically, yes. Most professional certifications require each candidate to complete a recertification process every few years. Specific requirements vary by credential, but this process often requires continuing education, proof of active employment, and recertification fees.

What certifications do I need to become a public health nurse?

Public health nurses, also called community health nurses, are registered nurses (RNs) who promote public wellness. RNs must obtain licensure by passing the NCLEX-RN examination. RNs can also pursue other public health certifications.
