What an assessment for AHCDES401 must cover

36 assessable components: 4 elements (16 performance criteria), 7 performance evidence and 10 knowledge evidence requirements, plus 3 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 Incorporate structures and features into a landscape design

1.1Identify and locate design structures and features to maximise efficient use of the space
1.2Identify and source any required preliminary specialist expertise
1.3Select materials that reflect the style and aesthetic of overall design concept
1.4Assess suitability of constructed elements in relation to physical properties of soils on site
1.5Assess effects of surface and subsurface water and drainage patterns on constructed elements
1.6Assess drainage requirements to ensure integrity of constructed elements in design

2 Determine construction requirements

2.1Evaluate factors that impact on selection and construction of elements in the design
2.2Select materials according to properties and application within the design
2.3Determine construction techniques that support design, fit timelines and meet budget requirements
2.4Identify surface treatments appropriate for selected materials and design

3 Assess the need for supplementary water in a landscape design

3.1Identify available water in the landscape
3.2Determine the feasibility of using available water in the landscape
3.3Identify appropriate irrigation methods to support the design
3.4Incorporate irrigation requirements into the design or design documentation

4 Source technical services and expertise

4.1Determine construction requirements beyond the scope of own expertise
4.2Determine and consult with technical and specialist services beyond own scope of expertise as required

Performance evidence

selected, in consultation with appropriate specialist representatives, appropriate construction methods for structures and features to suit site specific soil properties
identified and modified natural drainage patterns
determined appropriate drainage systems for the landscape design
incorporated into a landscape design constructed elements and drainage that meet the aesthetic and physical requirements of the site
assessed the need for supplementary water and suitability of available water on site to support landscape design
identified and specified where required appropriate waterwise irrigation systems
recognised limits of own expertise and sourced providers of technical services and specialist expertise when required

Knowledge evidence

landscape features and elements commonly used in landscape design projects
specialist and technical services commonly involved in the construction of landscape design projects
physical soil properties and their impact on constructed features
natural drainage patterns and modification methods
movement of water through soil
purpose and application of drainage systems
properties of construction materials commonly used in landscape design projects
construction techniques commonly required for landscape design projects
purpose and application of hydro zoning
different methods of irrigation

Foundation skills

Reading: Identify and interpret information regarding design concept requirements
Oral communication: Initiate discussions, using clear language and standard industry terminology to discuss and determine construction requirements
Numeracy: Estimate construction budget and timelines Take and record measurements Calculate quantities and cost of construction materials

Questions about assessing AHCDES401

What does an assessment tool for AHCDES401 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AHCDES401 needs to address all 36 unit components: 4 elements with 16 performance criteria, 7 performance evidence requirements, 10 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 AHCDES401?

Auditori pulls the current release of AHCDES401 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 AHCDES401 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AHCDES401 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 AHCDES401, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
