Registration for the Certified in Public Health (CPH) Exam is currently open but will close on September 20, 2013. CPH Exam testing will begin October 5-26, 2013. The National Board of Public Health Examiners (NBPHE) offers the CPH credential as the only voluntary core credential for public health professionals. The CPH designation demonstrates that an individual graduate from a CEPH-accredited school or program of public health has mastered foundational competencies in public health. CPH professionals raise the bar and enhance the public health profession through their exemplary academic and leadership skills.
