Since 1960, the American Board of Industrial Hygiene® (ABIH®) has been the world's largest, organization for certifying professionals in the practice of industrial hygiene. ABIH is not a member organization, therefore it does not provide services typically offered by member organizations; neither does it call for involvement in any member organization as a requirement for certification. ABIH understands the importance of impartiality in carrying out its certification activities, so the board and staff manage conflict of interest and ensure the objectivity of all certification activities.

The purpose of ABIH is to administer the Certified Industrial Hygienist® (CIH®) and the Qualified Environmental Practitioner® (QEP®), which are a means to objectively assess and measure the professional knowledge and understanding of practitioners engaged in industrial hygiene and environmental practice professions.  

ABIH Mission
The American Board of Industrial Hygiene® is the premier credentialing organization for professions based on the science of protecting and enhancing the health, safety, and environment of people at work and in their communities.  It serves its credentialed practitioners by establishing and administering a valid, reliable, and rigorous credentialing process to protect the public and meet the needs of employers.

ABIH Vision
ABIH®-credentialed practitioners are globally recognized as the epitome of professional competence and ethics in professions based on the science of protecting and enhancing the health, safety, and environment of people at work and in their communities.

ABIH Overview
The ABIH is an independent not-for-profit 501(c)6 organization, incorporated in 1960 by the State of Pennsylvania.  AT that time, it was devoted solely to the purpose of certification of industrial hygiene professionals, today, its certifications also include environmental practitioners. ABIH is governed by its own set of By-Laws. There are no formal relationships with any other organization to nominate or appoint people to serve on the ABIH Board of Directors. From time to time, ABIH enters into agreements or collaborative efforts with other organizations (e.g., AIHA, OHTA) where there are common interests (e.g. ethics awareness, IH promotions, certification research) but at no time does ABIH relinquish its decision-making authority for matters involving the operation of the ABIH.

In order to become a CIH, each Applicant must satisfy all educational, experience practice and other eligibility requirements established by the ABIH Board of Directors, and then must pass the Comprehensive Practice examination, based on actual practice through a Job Task Analysis.  Once certified by ABIH, Diplomates maintain their certification by successfully participating in the Certification Maintenance (CM) program which includes an on-going commitment to follow the ABIH Code of Ethics.

ABIH will evaluate all applicants, examinees, Diplomates and former Diplomates using the criteria set for CIH eligibility or certification and will not discriminate on the basis of race, creed, national origin, religion, age, disability, political affiliation, sex, sexual orientation, or marital, parental, military, or any other legally protected status. ABIH requirements for eligibility, certification, recertification or reactivation are applied fairly, impartially and consistently in accordance with ABIH policies and applicable laws.  ABIH policies and programs for initial certification, recertification and reactivation will be administered without regard to individual membership or non-membership in any organization, association or other group. 

ABIH's staff, volunteers and contracted-for services are committed to upholding the policies and procedures of ABIH to the best of their abilities. To demonstrate this commitment, these individuals are required to sign the ABIH Statement of Confidentiality, Assignment and Conflict of Interest form unless alternately covered by their own organization's confidentiality commitments and their legal contract with ABIH.  Exam Reviewers and Writers are required to sign a separate Security Agreement form. (Both forms are in the Document Library).

Documentation and information submitted to ABIH in support of its certification programs are treated as confidential, as specified in the ABIH Privacy Policy. All reasonable precautions are taken to prevent unauthorized access to individual information. ABIH does not disclose personal information obtained to third parties, except when authorized by the individual or if necessary to complete an ABIH process, e.g., arranging for an examinee to sit for the exam.

Questions or comments regarding the ABIH can be directed to the Chief Executive Officer.
