MSS024033 — Identify environmentally significant organisms

1 Obtain biological samples

• 1.1Locate and read site or project information to determine background and context of work
• 1.2Review work request to identify required samples and procedures, materials and equipment to be used
• 1.3Identify hazards and workplace control measures associated with collecting samples, preparation methods, reagents and equipment

• 1.6Log samples using workplace procedures
• 1.7Record sample description, compare with specification and note and report any discrepancies
• 1.8Apply traceability protocols from receipt of sample to reporting of results

2 Prepare samples and grow cultures

• 2.1Use aseptic techniques to prepare media for microbiological analysis
• 2.2Prepare samples for microbiological analysis according to procedures
• 2.3Identify contamination pathways for both samples and media and apply relevant controls
• 2.4Perform simple chemical tests to identify morphology of environmentally significant bacteria
• 2.5Use aseptic techniques to manipulate samples and bacterial cultures
• 2.6Use standard techniques to grow cultures of environmentally significant microorganisms
• 2.7Use disinfection and sterilisation to control the growth of microorganisms

3 Prepare microscope for use

• 3.1Select microscope and attachments for examination and measurements to meet work request
• 3.2Check that all microscope components are clean and fit for purpose
• 3.3Mount sample in accordance with specified method
• 3.4Adjust settings and alignment of optical and mechanical components to optimise performance

4 Perform microscopic examination in accordance with test methods

• 4.1Identify microorganisms, cell structures and components of animal and plant tissues in biological samples
• 4.2Measure organisms and structures
• 4.3Enumerate microorganisms in biological samples

5 Classify organisms

• 5.1Select and use dichotomous key to classify organisms into hierarchical structures
• 5.2Record all observations and measurements used to determine classifications according to workplace procedures

6 Determine environmental significance of organisms

• 6.1Identify cell structures of organisms
• 6.2Associate biological functions with cell structures
• 6.3Associate cell physiology and enzyme cycles to environmental adaptation relevant to site or project
• 6.4Identify important biochemical pathways associated with environmentally significant organisms

7 Maintain a safe work environment

• 7.1Use personal protective clothing and safety equipment to ensure safety and minimise cross-contamination
• 7.2Handle all samples and equipment in accordance with workplace safety procedures
• 7.3Clean up spills using techniques to protect personnel, work area and environment
• 7.4Minimise generation of waste and environmental impacts
• 7.5Collect and dispose of all waste safely
• 7.6Report hazards and incidents to designated personnel using workplace procedures

8 Maintain workplace records

• 8.1Record approved data into workplace system
• 8.2Maintain confidentiality and security of workplace information and data

What does an assessment tool for MSS024033 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MSS024033 needs to address all 60 unit components: 8 elements with 36 performance criteria, 1 performance evidence requirements, 20 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 MSS024033?

Auditori pulls the current release of MSS024033 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 MSS024033 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MSS024033 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 MSS024033, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
