MSL974028 — Classify soils

1 Prepare to classify soil samples

• 1.1Review job request and any accompanying documentation to identify purpose of soil classification and client’s information needs
• 1.2Identify any hazards and relevant safe work procedures associated with the types of site samples
• 1.3Inspect supplied samples and test data, compare with specifications and record and report any discrepancies
• 1.4Liaise with client when supplied samples, test data and/or job request forms do not comply with workplace procedures and resolve any problems
• 1.5Assemble required equipment/materials and check that they are fit for purpose

2 Examine properties of soil samples

• 2.1Assess appearance and feel of soil to determine moisture condition
• 2.2Use moulding/indentation tests, penetrometer and/or density index data to determine soil consistency
• 2.3Identify the soil’s major, secondary and minor components and the proportion of each
• 2.4Assign a soil colour based on own observations and review of field log sheets
• 2.5Determine soil structure based on own observations and review of available zoning, defect and cementing data recorded for undisturbed field samples
• 2.6Review any additional observations and test data that may identify soil origin

3 Analyse available test results

• 3.1Compare supplied mechanical test data with standard classification values for different soil types
• 3.2Compare particle size and percentage composition data with standard classification values for different soil types
• 3.3Compare other laboratory test results with own observations to confirm assignment of plasticity, grading and strength of soil samples
• 3.4Recognise anomalies or unexpected results and, if necessary, recheck specimens and test results and conduct repeat tests to ensure reliable results

4 Record soil classification

• 4.1Use standard symbols and descriptors to assign a valid soil classification
• 4.2Record and store client’s soil classification, samples and test data in accordance with workplace procedures
• 4.3Maintain confidentiality of client information in accordance with workplace procedures

5 Maintain a safe work environment

• 5.1Use safe work procedures and personal protective equipment (PPE) to ensure personal safety and that of other personnel
• 5.2Clean work area and collect, recycle or dispose of all waste in accordance with workplace procedures
• 5.3Clean and check serviceability of test equipment before storage

What does an assessment tool for MSL974028 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MSL974028 needs to address all 32 unit components: 5 elements with 21 performance criteria, 2 performance evidence requirements, 8 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 MSL974028?

Auditori pulls the current release of MSL974028 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 MSL974028 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MSL974028 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 MSL974028, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
