The Indoor Environmental Professional (IEP) training program is a six month part time course that comprises of two nationally accredited units (NAT10913005 and NAT10913009) and is designed to certify professionals at the highest national standard. Developed in collaboration with leading industry experts including two committee members for the first Australian Standard, this advanced qualification equips restorers, remediators, hygienists, plumbers, mould testing technicians, building surveyors and building professionals with the specialised expertise to conduct pre-remediation assessments and post-remediation verification testing in accordance with national standards.
What is an Indoor Environmental Professional?
An Indoor Environmental Professional (IEP) is an independent, nationally qualified specialist trained to assess and diagnose problems within the indoor environment, including mould contamination, water damage and microbial growth. An IEP evaluates how these conditions affect occupant health, building materials and the overall safety and habitability of a property. IEPs apply advanced knowledge of building science, moisture behaviour, microbiology, indoor pollutants, and relevant Australian Standards, guidelines and insurance requirements to conduct comprehensive assessments. They select and interpret valid sampling methods, develop or review mould and water-damage remediation scopes, and confirm successful restoration through clearance testing or post-remediation verification (PRV). Acting as an independent, evidence-based authority, an Indoor Environmental Professional works with various stakeholders including insurers, builders, restoration technicians, clinicians and occupants to provide defensible reports and clear recommendations that guide effective remediation and support healthier indoor environments.
About the Course
The Indoor Environmental Professional (IEP) course is developed by leading experts including committee members of the first Australian Standard. As the only nationally accredited training program of its kind in Australia, the course equips you with the full skill set needed to assess, test, and verify mould issues in water-damaged buildings, from initial inspection through to post-remediation clearance. Aligned with the newly released Australian Standard for mould assessment and remediation (AS-IICRC S520:2025), and this course ensures your practice meets current professional expectations and emerging regulatory benchmarks.
Course Structure
This is a 6 month part time course consists of two parts:
- Part 1: Mould Testing Pre-Remediation. This is a 12 week part time course that consists of 8 live (online) sessions plus two days field training. See timetable below.
- Part 2: Post Remediation Verification Testing. This is a 12 week part time course that consists of 8 live (online) sessions plus one day of field training. See timetable below.
What You Will Learn
You’ll gain the knowledge and hands-on capability to carry out comprehensive mould investigations, including:
Stakeholders, Health and Building Science
- Causes of mould and microbial growth, and the latest research on how dampness and mould impact human health, including susceptible groups such as children and people with asthma, allergies, and chronic inflammatory response syndrome
- Understanding basics of fungi, colonisation, amplification and how this is influenced by the material it is growing on
- How to understand and respond to the needs of key stakeholders, including occupants, insurers, loss adjusters, remediators, and health professionals
- Psychrometry and building science principles that govern moisture movement in buildings, why substrates matter
Assessment, Inspection and Moisture Mapping
- How to take a comprehensive environmental exposure history to guide your investigation
- How to conduct a thorough exterior and interior inspection, integrating thermal imaging, moisture meters, and moisture mapping
- Advanced techniques for moisture mapping in complex substrates such as plasterboard, masonry, and concrete, and an understanding of Australian Standards for testing moisture in concrete
Restoration Principles, Damage Classification and Sampling Strategy
- Restoration first principles, including differentiating event-related damage from secondary damage and pre-loss conditions, and recognising pre-existing or historical damage
- How to determine recovery levels (1 to 4) and align your approach with insurer expectations and policy requirements
- The difference between PRV and clearance testing, and when to apply presumptive and predictive sampling versus forensic and diagnostic sampling
- How to design and carry out sampling for mould and bacteria, including Category 3 water, using air, surface, and other appropriate methods
Insurance, Testing, Verification and Reporting
- How to manage insurance-related claims, policies, and documentation requirements for both insurable and non-insurable events
- How to carry out robust pre-remediation testing and post-remediation verification (PRV) in a way that stands up to scrutiny from clients, insurers, and regulators
- How to accurately interpret laboratory results, compare them to relevant exposure and guidance values, and translate technical findings into clear recommendations
- How to implement workplace safety and risk management, and write clear, defensible reports for post-remediation verification and ongoing risk control
What’s included:
This program provides everything you need to build confidence and competence in the field:
- Professional report templates for both pre-remediation assessments and post-remediation verification.
- Downloadable course materials including a comprehensive 300-page manual, and the latest scientific research on dampness for ongoing reference.
- Pre-recorded PowerPoint modules allowing you to review key concepts discussed during live zoom sessions.
- Sixteen live (online) sessions with industry experts with extensive experience in testing water damaged buildings, flooring failures, remediation, building biology and insurance—ask questions, workshop cases and learn from real examples.
- Three days of supervised field training conducted over two weekends in actual water-damaged buildings, where you’ll apply the full assessment-to-verification process under guidance.
