Part 1 of the Certification Exam of the American Board of Health Physics

Coordinated through Professional Testing (PTI).

Meaning of Certification

Certification indicates that the recipient has completed certain requirements of study and professional experience, which the Board considers to constitute an adequate foundation in health physics, and has passed an examination designed to test competence in this field. Holders of ABHP certification may identify themselves as either Certified Health Physicists (CHP) or Diplomates of the American Board of Health Physics (DABHP). It should be recognized that the certificate awarded by the Board is not a license and, therefore, does not confer a legal qualification to practice health physics.

Professional Responsibilities of Certified Health Physicists

In achieving certification, the CHP recognizes and assumes the responsibilities due the profession of health physics. To uphold the professional integrity of health physics implied by certification, the relations of the CHP with other individuals and groups, including clients, colleagues, governmental agencies, and the general public, shall always be based upon and reflect the highest standards of professional ethics and integrity. Each CHP has a professional and ethical obligation to practice only in those areas in which he or she is competent. To maintain technical competence, the CHP has a commitment to remain professionally active in the field of health physics and knowledgeable of scientific, technical, and regulatory developments in the field.


Before scheduling a CHP exam, you must meet the prerequisites, apply, pay the designated fee, and receive an Authorization-to-Test email from the ABHP.   For more information, visit the  AAHP Certification Website.
