What an assessment for MEM24028 must cover

53 assessable components: 5 elements (25 performance criteria), 10 performance evidence and 18 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 Establish job requirements

1.1Comply with relevant WHS and regulatory requirements, codes of practice and standards for ultrasonic testing
1.2Identify job requirements from specifications, drawings, job sheets, previous NDT results or work instructions

2 Prepare for testing

2.1Liaise with client to explain testing requirements and schedule tests to minimise disruption, as necessary
2.2Use established safe work practices and personal protective equipment to ensure personal safety and that of others
2.3Assemble all specified testing equipment, materials and containers and safety equipment
2.4Identify inspection areas and determine if special access requirements appropriate for the NDT test need to be communicated to the client
2.5Clean and prepare inspection areas for testing using appropriate test procedures and materials in accordance with WHS and regulatory requirements
2.6Assess inspection areas visually and identify obvious discontinuities

3 Conduct ultrasonic tests

3.1Select the most appropriate ultrasonic test technique for the material or application
3.2Select the most appropriate probe and instrumental set-up and prepare these in accordance with standards and standard operating procedures (SOPs)
3.3Conduct system verification checks and operate instrument in accordance with manufacturers’ specifications and SOPs
3.4Use appropriate calibration blocks to calibrate instrument for the expected thickness range in the material being tested
3.5Use appropriate reference blocks to optimise instrument response for expected discontinuities at the target depth
3.6Locate recordable discontinuities and evaluate their echo dynamics by varying probe orientation and location, as necessary
3.7Record ultrasonic test data for specified locations, angles, and depths in accordance with relevant standards and SOPs

4 Interpret and report results of ultrasonic tests

4.1Review conduct of the test and confirm test procedures were applied correctly
4.2Monitor and assess indications and determine the type of discontinuity for each relevant indication
4.3Apply acceptance criteria to discontinuities to detect defects
4.4Classify and confirm defects in accordance with relevant codes, standards and SOPs
4.5Seek advice for problems outside technical competence or knowledge
4.6Record any site observations that may affect results
4.7Report test results and complete all job records in accordance with relevant standards and SOPs

5 Maintain a safe work environment

5.1Minimise environmental impacts of testing and generation of waste
5.2Restore test site, clean inspection area and equipment and dispose of all waste in accordance with enterprise procedures
5.3Check, store and maintain ultrasonic testing equipment in accordance with standard operating procedures and manufacturer’s instructions

Performance evidence

preparing the inspection area on at least two specimens for testing and identifying discontinuities
complying with workplace procedures and WHS requirements during ultrasonic testing
identifying and interpreting specifications, standards, drawings, charts, lists and other reference material for performing ultrasonic testing on at least two specimens.

Questions about assessing MEM24028

What does an assessment tool for MEM24028 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM24028 needs to address all 53 unit components: 5 elements with 25 performance criteria, 10 performance evidence requirements, 18 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 MEM24028?

Auditori pulls the current release of MEM24028 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 MEM24028 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM24028 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 MEM24028, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
