Certified Commissioning Technician (CxT)


AABC Commissioning Group (ACG)


The Certified Commissioning Technician (CxT) is a second-tier certification for those who do not yet possess the technical, industry, or commissioning experience to qualify for the CxA. CxT candidates must work for an ACG member company, under the supervision of a CxA. Additional prerequisites for CxT certification include a minimum of two years field testing experience, at least 6 months working for the ACG member company at which the candidate is presently employed, and endorsement by a CxA at that company.


Candidates must attend an ACG workshop or webinar before becoming certified. See ACG CxA description for training details.


The multiple-choice exam is closed-book and lasts 3 hours. It is based on material in the ACG Commissioning Guideline and the CxT Study Guide (PDF). Candidates can schedule the exam at testing centers in most metropolitan areas or sit for it immediately after a workshop or seminar. The passing score is 70%.
