Mold Certifications Explained

The first thing that is important to understand is that mold is not regulated by the State of California. Unlike lead and asbestos which are regulated by the state, there is no license that is required to perform mold testing. This creates a paradox of sorts because many people suffer terribly from mold exposure, but the industry is for the most part not being regulated, which allows for scams and unqualified companies to exist within the industry without much recourse for consumers.

Why is NCET's certification "prestigious"?

The "CIE" Certification is prestigious because it is geared specifically towards indoor environmental testing. If one desired to be an expert in mold testing this is the certification they would aspire to earn. In order to earn this certification one must demonstrate an in-depth knowledge of mold related tests and inspections as well as the ability to interpret laboratory data, and create protocols for mold remediation.


There are companies who charge substantially more money for their mold tests and/or site visits because they employ Certified Industrial Hygienist's (CIH). The CIH is not geared towards mold testing per se. A CIH is a professional who specializes in work place safety. They deal with lighting issues, carpal tunnel, ergonomics, chemical exposure, work place noise related matters, etc. The CIE is a mold and indoor air quality expert. The CIE certification is regarded as an expert by various lawyers, judges, insurance companies, and doctor's across the USA.

What about the other mold testing certifications?

The majority of other certifications are online certifications. Essentially, to earn one these certifications one must pay a required membership fee and take an open book online test. In order to earn the CIE certification one must have a minimum of 2 years field experience, pass a closed book test at a certified testing facility, and fulfill the annual continuing education requirements to maintain the certification.

The other strategy employed by some is to join various organizations and put their logo on their website. These are just membership's, which anyone who is willing to pay can join. NCET is by no means saying that joining industry related organizations is a bad thing. We really just want to educate consumers on what all of the certifications actually mean.
