Training, education, and certification are essential to the
development of competent test and balance personnel.


  • Once a company is approved for AABC membership by the Board of Directors and has at least one
    (1) individual successfully pass the Test and Balance Engineer (TBE) exam, that agency officially becomes
    an AABC-Certified Member Agency.
  • An Annual Membership Certificate is issued to all member companies each year that verifies that
    the agency is entitled to all rights and privileges of AABC certification, as long as the member remains
    in good standing.


  • All AABC member agencies must have at least one certified TBE on staff. The TBE is ultimately
    responsible for overseeing technical operations of the company; reviewing and certifying test
    and balance reports; and providing supervision and training of technicians.
  • To be eligible for certification as a TBE, the applying individual must have a minimum of eight
    (8) years test and balance experience. Applicants with engineering degrees will receive four (4)
    years credit toward the experience requirement.
  • The TBE examination is a rigorous, 8-hour written examination—now offered through a network
    of secure, computer-based local testing centers—that tests applicants’ knowledge and technical
    competence in air and hydronic systems balancing including fan and pump laws, psychrometrics
    and heat transfer, electrical systems, sound and vibration testing, instrumentation and TAB
    project management.
  • Candidates who pass the examination are issued a TBE certification number and Annual Certificate.
  • Certification is renewable on an annual basis, and is only valid while employed by an AABC member firm.


  • AABC requires that all eligible technicians employed by member agencies be certified. Eligible technicians
    are defined as those with a minimum of three (3) years test and balance experience who have
    been employed by an AABC agency for the past 12 months.
  • In addition, technicians must be competent in air, water, sound, and vibration testing. Technicians
    must also be able to perform all work in accordance with the AABC National Standards. The final
    requirement for certification is that technicians pass the required examination.
  • Technicians who receive a passing score on the certification examination are issued a Technician
    certification number and an Annual Certificate. Technician certification is renewable on an annual
    basis, and is only valid while employed by an AABC member firm.
  • Candidates for technician certification undergo intensive field training in addition to classroom
    instruction. Each AABC member agency is responsible for the administration of in-house training
    programs for their employees.


  • Employees of AABC member companies must be able to demonstrate their knowledge of cleanroom
    applications and testing procedures, in accordance with industry accepted standards and
  • Requirements for certification include maintaining certification as an AABC TBE or Technician
    and receiving a passing score on the cleanroom certification examination.
