Membership and certification are open to independent commissioning companies that meet the requirements for membership and pass the ACG Certification Examination. The applying company must submit a completed membership application, and the ACG Examining Board will evaluate the application for acceptance.

Upon approval of the application, the company’s designated individual will be permitted to take the ACG certification exam at the next available offering. If the candidate passes the examination, the individual and company for which he or she works is granted certification as an ACG Certified Commissioning Authority (CxA). Certification is issued in the name of the company and designated individual, who must be a registered engineer, licensed architect, or certified test and balance engineer.

Associate Membership is available to individuals who subscribe to the goals and objectives of ACG, but are not actively engaged in providing services as a commissioning authority. Associate membership does not require or imply ACG Certification.
