What an assessment for AHCSOL304 must cover

43 assessable components: 4 elements (18 performance criteria), 12 performance evidence and 11 knowledge evidence requirements, plus 2 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare and collect soil samples for testing

1.1Identify purpose and method of soil sampling and testing
1.2Select tools, equipment and materials required for safely collecting soil samples according to testing procedures
1.3Collect representative soil samples for testing
1.4Package and label soil samples ready for testing according to laboratory procedures

2 Determine physical characteristics of sample

2.1Conduct tests to determine the physical characteristics of soils according to laboratory procedures and safe work practices
2.2Identify depth of topsoil and assess suitability for cultural requirements of plants to be grown
2.3Assess soil physical characteristic test results to determine drainage and water holding performance
2.4Identify and select soil improvements required to meet cultural requirements of plants to be grown
2.5Prepare a soil improvement plan for improving physical characteristics

3 Determine chemical characteristics of sample

3.1Conduct tests to determine chemical properties of soil according to laboratory procedures and safe work practices
3.2Assess soil chemical properties test results to determine effect on cultural requirements of plants to be grown
3.3Identify and select soil chemical improvements required to meet cultural requirements of plants to be grown
3.4Update soil improvement plan for improving chemical characteristics

4 Prepare soils for planting or replanting

4.1Select tools, equipment and materials required to safely incorporate soil treatments according to soil improvement plan
4.2Calibrate equipment to ensure application of soil improvement material complies with improvement plan
4.3Implement soil improvement plan for garden and turf areas
4.4Adjust soil levels and consolidate ready for planting
4.5Record and report work outcomes according to workplace procedures

Performance evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.
There must be evidence that the individual has collected soil samples, including:
• determined the purpose for collecting and testing soil samples
• collected representative soil samples for testing and packaged and labelled them according to workplace and laboratory requirements
• collected samples of at least three different soil types, and:
• conducted tests safely to determine soil physical and chemical properties according to industry standards
• assessed test results and prepared soil improvement plan to meet the requirements and conditions required for the plant species to be cultivated.
There must also be evidence that, on at least one occasion, the individual has, according to workplace procedures:
• selected tools, materials and equipment required for implementing soil improvement plan
• calibrated equipment prior to application of soil improvement materials
• adjusted physical and chemical properties according to cultural requirements of the plants to be grown
• maintained records and reported soil test outcomes.

Knowledge evidence

physical properties of soils and media and methods for testing, including: colour, organic matter, texture tests using field and sieve analysis techniques, structure, air filled porosity, moisture holding capacity, soil bulk density, infiltration rate and drainage properties, including hydraulic conductivity, perched water tables, wettability
chemical properties of soils and media, and methods for testing, including: pH using colorimetric and pH meters, salinity, total dissolved salts and electrical conductivity, types of nutrient tests and their purpose
soil sampling, collecting and testing procedures, including: tools and equipment required, procedures for testing, procedures for sampling, securing, packaging and labelling
soil and media improvement strategies for physical and chemical characteristics, including: products and processes for improving soil and media physical condition, soil ameliorants and improvement techniques, bio-stimulants, organic matter and effect on soil and media, water holding capacity and readily available water, including wetting agents and penetrants, soil biological organisms and their impact, effect of pH, salinity and fertilisers on availability of nutrients
soil profile both natural and constructed
Australian standards AS4454:2012 Composts, soil conditioners and mulches, and AS4419:2018 Soils for landscaping and garden use
assessment and interpretation of soil test results for physical and chemical properties and their relationship to cultivated plants relevant to workplace
basic mathematics for calculating rates of application of soil additives, water holding capacity, air filled porosity and measuring and weighing materials to perform accurate soil tests
using test results to determine soil improvements
safe field and laboratory practices when collecting and testing soils and media
record keeping and reporting procedures for soil collecting, testing and planning procedures

Foundation skills

Writing: Complete workplace documentation accurately and clearly using industry terminology, correct spelling and required format
Numeracy: Perform weight and volumetric measurements when preparing and assessing soil tests; Calculate soil improvement materials to include in the soil improvement plan, including distance, area, volume and ratio

Questions about assessing AHCSOL304

What does an assessment tool for AHCSOL304 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AHCSOL304 needs to address all 43 unit components: 4 elements with 18 performance criteria, 12 performance evidence requirements, 11 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 AHCSOL304?

Auditori pulls the current release of AHCSOL304 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 AHCSOL304 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AHCSOL304 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 AHCSOL304, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
