The certification is valid for a period of 2 years, at which point renewal is required.  Renewal does not require a retest, just a proof of ABAA and AIA LUs/CEUs. After that, every six years a Certified Air Barrier Specialist must recertify to confirm continued compliance of the certified person. This will require a written exam, among other requirements.

We recommend a minimum of 5 years of industry experience, along with ABAA Continuing Education units (CEU).

To best prepare for the certification exam, we recommend extensive industry readings and a thorough review of the ABAA CABS Study Manual and Program Handbook.
