One way to measure the quality of a certification program is to evaluate its accreditation status. Accreditation is a form of certification for the certifying organization, requiring conformance with standards of validity, reliability and impartiality.
IHMM certification credentials have been granted accreditation by the American National Standards Institute (ANSI). The CHMM and CHMP credentials were accredited in 2009 and CDGP was accredited in 2015. The ANSI accreditation program is based on the International Standard ANSI/ISO/IEC 17024, Conformity assessment – General requirements for bodies operating certification of persons. IHMM credentialing programs have been reaccredited each year via a vigorous ANSI annual surveillance process. ANSI accreditation is recognized both nationally and internationally and has become the hallmark of a quality certification program.
The IHMM CHMM and CHMP certification programs are accredited by The Council of Engineering & Scientific Specialty Boards (CESB). CESB is an independent, voluntary membership body for organizations who recognize, through specialty certification, the expertise of individuals practicing in engineering and related fields. Accreditation is earned by demonstrating adherence with CESB Accreditation Guidelines, including a robust review program of compliance to those standards.
Holders of the CHMM credential who have five years of experience in hazardous substance remediation may pre-qualify for the Cleanup Star site remediation program of the New Jersey Department of Environmental (NJDEP). CHMMs in Connecticut may supervise and sign off on wastewater permits/aquifer protection plans. In Indiana, CHMMs are authorized to sign plans for soil remediation in underground storage tank (UST) closure projects. In the State of New York, CHMMs are recognized as Qualified Environmental Professionals for the purpose of certifying Institutional Controls/ Engineering Controls (ICs/ECs), for Environmental Restoration Projects, State Superfund Projects, Brownfields Cleanup Projects, and Voluntary Cleanup Program Projects. In the Commonwealth of Pennsylvania, the CDGT and CHMM and recognized as Accident and Illness Prevention Service Provider under 1001(a) and (b) of the act (77 P.S. Sec 1038.1 (a) and (b)).
Federal agencies seeking qualified personnel to fulfill their needs are also turning to professionals with the CHMM certification. The US Army Center for Health Promotion & Preventive Medicine recognizes the CHMM as a USACHPPM Professional Certification. The US National Park Service requires supervision by a CHMM in many of their requests for proposal. Contracts that include the CHMM credential have also been issued by the US Air Force, the US EPA, the US Army Corps of Engineers, the Department of Veterans Affairs, the FDIC, and other Federal and state agencies.
Corporations throughout the country have recognized the significance of credentialing their environmental professionals, and their preference is the CHMM certification. Some of the companies encouraging their professionals to attain the CHMM credential include: AARCHER, ENSR, 3E, Teris, Tetra Tech, Shaw Group, URS, Terracon, Sara Lee, Public Service Electric and Gas (NJ), Boeing, Delphi, and General Motors Corp.
Accreditation by ANSI and CESB demonstrates that IHMM's credentials meet standards for:
- Validity of the certification examination program
- Fairness of the procedures for determining applicant eligibility
- Adequacy of requirements for ensuring maintenance and enhancement of professional qualifications (recertification)
- Professionalism and independence of the certifying body
- Openness of the program to public scrutiny
