CIEIT vs. CIAQTT Certification: The Difference
Some professionals may wonder how this differs from our Certified Indoor Air Quality Testing Technician (CIAQTT) program.
While the CIAQTT focuses strictly on identifying IAQ problems and air sampling, the CIEIT course goes much deeper into the physical building itself. It trains you on structural evaluations and complex moisture intrusion tracing. If you are already a CIAQTT, adding the CIEIT certification is a must to complete your investigative skillset.
