What is an Indoor Environmental Professional (IEP)?
IEP is an umbrella category that covers Building Biologists, ACAC certified inspectors, Mycologists/Microbiologists and Occupational (Industrial) Hygienists.

These professionals are able identify the source and extent of water damage, moisture and, if necessary, amount and location of microbial growth via sampling. They can also determine the required scope of works to return the property to pre-event condition, and after remediation,  provide post-remediation verification. They may send mould samples to micro/myco-biologists or other laboratories for analysis and quantification.

Should the mould/building inspector be different from the remediator?
Yes, ideally.

According to the IICRC S520 Mold Remediation standard, p17:

4.2.1 Assessment
When a preliminary determination indicates that mold contamination exists or is likely to exist, an assessment should be performed prior to starting remediation. An independent IEP who has no business affiliation with the remediator should be used for this purpose. In circumstances where an entire building or system is fully involved as a result of Condition 3 mold contamination or when the scope of work can be determined without sampling or independent IEP inspection and assessment, engagement of an IEP for assessment may not be necessary. Notwithstanding the foregoing, if health issues are discovered or apparent that seem to be related to the actual or suspected mold contamination, an IEP or other appropriate professional should be engaged by the property owner and the extent and Condition (1, 2 or 3) to which areas of the structure, systems and contents are potentially mold contaminated should be assessed, documented, and reported to the client.
Likewise according to the ACAC code of conduct:

Note on Conflicts of Interest:

The American Council for Accredited Certification strongly discourages its certificants from performing both assessment services and contracting services on the same project.  Certificants who offer both services to the same client create a perceived conflict of interest regardless of their integrity.  Nevertheless, as circumstances sometimes prevent the employment of multiple professionals on the same project, ACAC does not prohibit the practice, nor does ACAC make compliance with this policy a condition of continued certification.

What type of IEP does Toxic Mould Support Australia favour?
TMSA does not favor one group of professionals over another for the investigation and remediation of water damage and microbial growth in buildings. Neither can we personally vouch for any of the professionals below — do your due diligence and own research.


Environmental Relative Moldiness Index is a test that quantifies the DNA of mould spores and spore equivalents (fragments) in a sample of dust using MSQPCR (Mould Specific Quantified PCR). This is a screening test that can be done by current and prospective homeowners or ideally by IEP/BB/mycologist. ERMI tests for 36 different species of fungi. The HERTSMI-2 score can be calculated from the ERMI report or done as a stand alone test, that looks at 5 species of fungi. The HERTSMI-2 score is endorsed by Dr. Shoemaker as the most accurate building test for CIRS patients (Shoemaker & Lark, 2016).
