Frequently Asked Questions

What are the eligibility requirements to sit for the CPH exam?

The primary eligibility pathway requires a degree (bachelor's, master's, or doctoral) from a school or program of public health accredited by the Council on Education for Public Health (CEPH). Individuals with a relevant graduate degree and public health work experience may also qualify. All candidates must submit an application and fee to the NBPHE for approval. Current students in CEPH-accredited programs can often take the exam prior to graduation.

How is the CPH exam structured and what is the format?

The CPH exam is a computer-based test consisting of 200 multiple-choice questions, of which 175 are scored. Candidates have 4 hours to complete the exam. Questions are derived from the official exam blueprint, which covers domains such as Evidence-Based Approaches, Public Health & Health Care Systems, Planning & Management, Policy, Leadership, Communication, and Interprofessional/Intersectoral Practice, in addition to the five core disciplines.

Is the CPH certification time-limited, and how is it maintained?

Yes, CPH certification is valid for two years. To maintain certification, certificants must earn 50 continuing education (CPH) credits within each two-year recertification cycle. These credits must include at least 21 credits from Category I (e.g., structured education) and at least 21 credits from Category II (e.g., professional contributions, teaching, self-study). The NBPHE provides a detailed framework for acceptable activities.

How does the CPH differ from other public health credentials, like the REHS/RS?

The CPH is a broad, cross-cutting credential validating foundational knowledge across all domains of public health. It is designed for generalist practitioners. In contrast, credentials like the Registered Environmental Health Specialist/Registered Sanitarian (REHS/RS) are specialized, discipline-specific certifications focused deeply on environmental health regulations, inspections, and enforcement. The CPH and specialized credentials can be complementary, representing different dimensions of professional expertise.

What resources does the NBPHE recommend for exam preparation?

The NBPHE considers the CPH Exam Content Outline (blueprint) the essential guide for preparation. They offer official study resources, including a Qbank with practice questions and a comprehensive Review Guide. Additionally, candidates are strongly encouraged to utilize materials from their CEPH-accredited graduate coursework, as the exam is based on the competencies taught in these programs. Many universities and professional organizations also offer review courses.
