3 Years


NITC’s Mechanical Acceptance Test Technician Certification is based on the California Code of Regulations 2013 or 2016, Title 24, Part 1, Sections 10-102-103-B and Part 6, Section 120.5. Title 24 mandates Acceptance Tests to ensure that the mechanical equipment that was specified is installed and operating as intended.

Acceptance Tests can only be performed by Acceptance Test Technicians (ATT), who are building specialists trained and certified by an Acceptance Test Technician Certification Provider (ATTCP). They are hired by Acceptance Test Employers (ATT Employers) to conduct the required test, and submit the results and certificates to enforcement agencies. Their employers are also required to have specialized training by an ATTCP.

A Mechanical Acceptance Test Technician certification candidate is a qualified individual who (1) meets the eligibility requirements, (2) can demonstrate competence within their scope, and (3) will be experienced in the inspection procedures and functional performance test procedures that serve to determine whether specific building mechanical systems conform to the criteria set forth in the California Building Energy Efficiency Standards. Acceptance Test Technicians (ATT) are also referred to as “Field Technicians” in the Standards.

The intention of the National Inspection Testing Certification (NITC) accreditation is to establish that NITC certified technicians are skilled craftsmen proficient in successful completion of the Mechanical Acceptance Tests mandated by the Standards.
