Refer to IAC2 Mold Inspection Standards of Practice prior to performing any visual examination.
I am impressed, the standards looks great. It appears more like the IESO standard that we use than the ESA standard does. We perform radon testing for dozens of home inspectors that are not certified in Florida for radon; we see some sad mold “inspections” being performed by home inspectors (some interNACHI, some not). This should help, since most are too cheap to spend $25 for the IESO standard we suggest they read. You have provided a much needed service with your free standard. (13 home inspectors in our area collect their outside sample on the porch)
Now all is needed is for the home inspector pretending to do mold inspections is that they read it.
Question: Why would you use a Z5 when performing a real mold inspection?
"The Z5 sampling cassette is a cost effective, first-line mold screening tool that efficiently and reliably collects mold. It can be easily used by home inspectors to get preliminary information on whether a mold problem may exist and further investigation is warranted."
