• 5.6Perform measurements and tests on samples and standards, if appropriate, in accordance with specified methods
• 5.7Keep accurate, complete and traceable records of field observations and test results

6 Clean, decontaminate and/or dispose of contaminated equipment and materials

• 6.1Inspect equipment to assess the degree of contamination
• 6.2Use specified procedures to remove material from the exposed outer surfaces of sampling and test equipment and PPE
• 6.3Use specified procedures and reagents to neutralise, wash and/or rinse exposed surfaces
• 6.4Collect rinsate blanks for analysis and preserve and store in accordance with specified procedure or standard
• 6.5Prepare and stow items for safe transport
• 6.6Safely collect all debris and sullage from decontamination in accordance with relevant regulations and codes

7 Finalise site activities

• 7.1Arrange for the safe disposal of hazardous wastes in accordance with relevant regulations and codes
• 7.2Ensure site observations, sampling and test data and results are accurately transferred to the workplace information management system
• 7.3Store samples in accordance with test method, chain of custody requirements and any relevant codes
• 7.4Ensure samples are dispatched for analytical testing within recommended holding times

8 Process and interpret data

• 8.1Review test and monitoring data noting atypical observations
• 8.2Calculate required quantities using relevant test method and ensure values are consistent with expectations
• 8.3Estimate and document uncertainty of measurement, if relevant, in accordance with workplace procedures
• 8.4Record processed results in accordance with workplace procedures
• 8.5Interpret trends in data and/or results and report atypical results promptly to relevant personnel
• 8.6Determine if obvious procedure or equipment problems have led to atypical data or results
• 8.7Compare results with established threshold levels or environmental quality concentration limits, as relevant
• 8.8Finalise reporting of results in accordance with workplace requirement

9 Maintain a safe work environment

• 9.1Clean equipment, instruments, containers, work area and vehicles according to workplace procedures
• 9.2Check serviceability of all equipment and instruments before storage
• 9.3Use defined safe work practices and PPE to ensure personal safety and that of others
• 9.4Minimise the generation of waste and environmental impact according to procedures

What does an assessment tool for MSS025029 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MSS025029 needs to address all 75 unit components: 9 elements with 52 performance criteria, 5 performance evidence requirements, 14 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MSS025029?

Auditori pulls the current release of MSS025029 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MSS025029 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MSS025029 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MSS025029, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
