What an assessment for MEM24043 must cover

44 assessable components: 5 elements (21 performance criteria), 8 performance evidence and 15 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

1.1Comply with relevant WHS and regulatory requirements, codes of practice, standards, and standard operating procedures for ultrasonic thickness testing
1.2Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.3Identify job requirements from specifications

2 Prepare for testing

2.1Assemble all specified testing equipment, materials and containers and safety equipment
2.2Identify inspection area and determine if special access requirements are required
2.3Clean and prepare inspection areas for testing using appropriate test procedures and materials
2.4Assess inspection areas visually to identify obvious discontinuities and faults

3 Conduct ultrasonic thickness tests

3.1Use the test technique specified in work instructions or standard operating procedures (SOPs)
3.2Conduct system verification checks and operate thickness gauge in accordance with manufacturers’ specifications and work instructions
3.3Use appropriate calibration blocks to calibrate the gauge for the expected thickness range in the material being tested
3.4Record thickness data and any relevant observations about the signal waveform, test piece and/or site conditions
3.5Review conduct of the test and confirm test procedures were applied correctly
3.6Recognise thickness results that indicate possible discontinuities and faults
3.7Perform additional measurements to determine the extent of possible abnormalities

4 Report the results of ultrasonic thickness tests

4.1Confirm thickness results and presence of possible abnormalities for test pieces in accordance with relevant standards and SOPs
4.2Seek advice for problems outside technical competence or knowledge
4.3Report test results and relevant observations and complete all job records in accordance with relevant standards and SOPs

5 Maintain a safe work environment

5.1Use established safe work practices and personal protective equipment to ensure personal safety and that of others
5.2Minimise environmental impacts of testing and generation of waste
5.3Restore test site, clean inspection area and equipment and dispose of all waste in accordance with enterprise procedures
5.4Store and maintain ultrasonic thickness testing equipment in accordance with standard operating procedures and WHS requirements

Questions about assessing MEM24043

What does an assessment tool for MEM24043 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM24043 needs to address all 44 unit components: 5 elements with 21 performance criteria, 8 performance evidence requirements, 15 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 MEM24043?

Auditori pulls the current release of MEM24043 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 MEM24043 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM24043 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 MEM24043, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
