Mould Testing Technician

The Mould Testing Technician unit (10913005NAT) is the only government accredited training in Australia to certify mould assessors. It has been developed for building managers, trades (building and construction), loss adjusters, industrial hygienists, mould remediators, professional cleaners, building biologists, pest controllers, health practitioners and anyone who wants a career assessing water-damaged buildings (WDB).

The course is 12 weeks in duration and consists of 8 evenings of online zoom sessions PLUS 12 weeks of self-directed online learning PLUS field training (timetable below). You will learn about the principles of psychrometry; how to take an environmental exposure history; conduct a thorough site inspection for moisture and moisture-laden materials; use meters to quantify indoor air readings, moisture meters for various substrates and thermal imaging; establish a sampling plan to undertake air, surface and dust sampling; and analyse laboratory results. Numerous real-life case studies will be presented by experienced building biologists to consolidate the information in the course. Whilst the course will discuss what is required to remediate a water-damaged building, the focus will be on testing a water-damaged building, NOT mould remediation (this course does not qualify you to work as a mould remediator).

For more information, refer to the Unit of Competency: (NAT10913005) Conduct an assessment of a water-damaged home (HERE).

Entry Requirements

You must be at least 18 years of age; apart from that there are no prerequisites and we assume no previous knowledge or experience in the building or restoration industry. Candidates are expected to have a high level of language and literacy skills sufficient to analyse and interpret complex documents, be prepared to learn specialised vocabulary appropriate to the restoration industry, comprehend video lectures, participate in field training, adapt spoken language to a range of clients, analyse laboratory reports, prepare written reports to provide precise meaning which meets audience purpose, interpret graphs and tables, and use computer software.


Successful completion of the Mould Testing course will be credited towards the Advanced Diploma of Building Biology (10913NAT).

In this course you will learn

  • evidence for the impact of dampness on human health,
  • how to take an environmental exposure history,
  • conduct a site inspection for sources and sign of moisture ingress,
  • conduct moisture mapping and identify moisture-laden materials,
  • undertake biological monitoring (air, dust and surface sampling),
  • establish the boundary of fungal particulate spread,
  • analyse laboratory results and compare to relevant exposure standards,
  • implement workplace safety and risk management,
  • how to write professional reports.

What will I receive when I successfully complete this course?

Upon successful completion, you will become an ACES Certified Mould Testing Technician. You will receive a nationally accredited Statement of Attainment for NAT10913005 Conduct an assessment of a water-damaged building, a Certificate and ID card to verify you are an ACES certified Mould Testing Technician.

*Field Training Options

(Choose from ONE of the following options)

Thursday evenings (6.15pm to 9.30pm)

4th August to 15th September plus 6th October 2022

OPTION 1: attend ONE of the following field trips (9.30am to 5pm)

  • Saturday 1st October Venue: Sydney NSW
  • Sunday 2nd October Venue: Melbourne VIC
  • Saturday 12th November Venue: Gold Coast, QLD
  • Saturday 10th December Venue: Sydney, NSW
  • Sunday 11th December Venue: Melbourne, VIC
Thursday evenings (6.15pm to 9.30pm)

3rd November to 15th December 2022

OPTION 2: Restorers, hygienists or mould remediators with extensive experience in mould remediation who have their own equipment and appropriate insurances, may choose to conduct an assessment of a water-damaged home of their choice. The testing must take sufficient samples (ideally test every room in the home, subfloor and roof) to conduct a thorough assessment of a water-damaged home and you will be liable to pay out of pocket laboratory costs. If insufficient samples do not allow the trainer to adequately assess your knowledge and skills from the information provided in your report, you will need to undertake the assessment again. You will need to provide the client’s contact details to verify you conducted the assessment.


Field training and COVID

There are currently no vaccine mandates required for students enrolled in our courses. Whilst students attending onsite (field training) are not required to show evidence that they have received two doses of a COVID-19 vaccination, they are encouraged to practice social distancing, regular handwashing and use of sanitiser, and take regular breaks outside. In the likelihood this changes due to State and Federal Government directions, students will be immediately notified. QR Code check-in requirements are no longer required however trainers will continue to complete class rolls for field training. Staff and students are no longer required to wear masks. For more information, refer to our COVID Policy.


Total cost is $1,995 and includes access to all of the online learning materials (downloadable comprehensive manual, videos of the lectures, access to peer reviewed papers) from the day of enrolment, PLUS eight evenings of live ZOOM sessions PLUS field training. Students who choose to hire the equipment (as opposed to attend field training) will incur additional costs outlined HERE and be subject to the Terms and Conditions of hire (HERE). Students will be provided with the contact details of their trainer for the duration of the course. Students are not required to buy any equipment to attend this training, however you will be required to purchase two text books: ANSI/IICRC S520-2015 Standard Guide for Professional Mold Remediation ($120); and Healthy Home Healthy Family ($40). In addition it is highly recommended that students bring their own full face respirator (preferably one that has been fit tested) to the field trip. For details about this, contact the college.


The assessments are designed to ensure you have the knowledge, skills and templates to conduct an assessment of a water-damaged building. The assessments include developing a questionnaire and checklist and writing a report, and completing an online quiz. You will be provided with a mould report template that can be used in your business.
