A large nonprofit trade group, the National Association of Mold Inspectors, certifies inspectors for mold detection. As part of the certification process, 60 hours of formal education must be completed. Another part of the certification process is taking and passing exams at various locations.
As of early 2011, no federal certification standards exist for mold inspectors. Therefore, the possibility of fraudulent schools and inspectors is present. Anybody can call himself a "Certified Mold Inspector," but the title is questionable. You have to look around for a school that provides professional references, such as belonging to trade associations or approved by local health departments.
Your state may have requirements for mold inspectors and mold inspection schools. This can vary widely from state to state. For example, the state of Texas has formal license requirements for Mold Inspectors. Find out what your state requirements are for licensing. Then inquire at schools regarding training to pass the state licensing exams. Any reputable school should be able to do this.
Most mold inspectors are self-employed, charging per inspection. You must present yourself in a very professional manner to real estate agents, home inspection agencies and to buyers and sellers of a home. This includes having the correct equipment and having the collected samples sent to a professional lab for a report. Work closely with local health departments, and find out what the criteria are for buildings.
