What an assessment for MEM48025 must cover
23 assessable components: 3 elements (10 performance criteria), 5 performance evidence and 8 knowledge evidence requirements. 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 Determine job requirements
- 1.1Follow standard operating procedures (SOPs)
- 1.2Comply with work health and safety (WHS) requirements at all times
- 1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
- 1.4Identify job requirements from specifications
2 Select surface treatment methods for specific applications
- 2.1Determine the surface preparation and treatment requirement for the specific application based on treatment properties, process routes, advantages and disadvantages
- 2.2Select the surface treatment method based on the requirement and consideration of principal properties
- 2.3Confirm selection according to standard operating procedures
3 Verify selected surface treatment methods as fit for purpose
- 3.1Identify appropriate tests for the required properties
- 3.2Arrange testing of coatings with internal or external parties based on testing requirements
- 3.3Analyse test results and confirm or modify material choices based on test outcomes
Performance evidence
- following work instructions, standard operating procedures (SOPs) and safe work practices
- identifying and interpreting specifications, charts, lists, drawings and other applicable reference documents in selecting surface treatment methods for metallic components or products
- researching the surface treatment methods by their principle properties
- selecting surface treatment process and materials to match application outcome on at least two occasions
- arranging tests appropriate to the metal or alloy and surface treatment material and analysing the results on at least two occasions
Knowledge evidence
- safe work practices and procedures and use of personal protective equipment (PPE)
- surface preparation methods
- theory of electroplating

Questions about assessing MEM48025
What does an assessment tool for MEM48025 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM48025 needs to address all 23 unit components: 3 elements with 10 performance criteria, 5 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 MEM48025?
Auditori pulls the current release of MEM48025 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 MEM48025 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEM48025 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 MEM48025, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
