The CPH Study Guide was developed by public health subject matter experts and does not guarantee a passing score on the Certified in Public Health (CPH) Certification Examination. The CPH Certification Program is governed by the National Board of Public Health Examiners (NBPHE). The NBPHE Board of Directors and NBPHE certification staff are not involved in the development of any preparatory resources, and no preparatory resource is endorsed by NBPHE nor is a prerequisite to earn the CPH certification. The NBPHE Board of Directors and NBPHE certification staff are solely responsible for the policies and administration of the CPH Certification Program. Learn more about CPH certification.
