What an assessment for MEM27008 must cover

51 assessable components: 4 elements (19 performance criteria), 10 performance evidence and 22 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, drawings, job sheets or work instructions

2 Assess induction and exhaust system operation

2.1Apply principles, terminology and applications of supercharging, filtering, inter and after cooling to assess induction and exhaust system operation
2.2Obtain relevant information and interpret prior to any testing
2.3Undertake checks safely and to prescribed testing procedures
2.4Determine and record flows, pressures and temperatures
2.5Isolate faults to component level and determine appropriate corrective action using appropriate test instruments and equipment

3 Assess emission control system operation

3.1Inspect emission control system components against manufacturer specification
3.2Check fuel evaporative control system and engine crankcase ventilation
3.3Service, adjust or replace components to manufacturer specifications, workplace procedures and WHS and environmental requirements

4 Rectify faulty components

4.1Determine component wear and clearances using manufacturer recommendations
4.2Determine if faulty components should be repaired or replaced
4.3Repair faulty components where appropriate
4.4Select replacement components using manufacturers’ data
4.5Remove and refit repaired or replacement components to engine
4.6Record all test and rectification activities
4.7Ensure engine is free of air and exhaust leaks after repair work is carried out

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
identifying and interpreting specifications, charts, lists, drawings and service documents to maintain induction and exhaust systems
checking induction and exhaust system for correct operation
checking emission control system performance for correct operation against specifications
using test instruments and equipment to isolate faults down to component level and visually and dimensionally checking components for wear against specifications
undertaking calculations and numerical operations to maintain induction and exhaust systems
removing and refitting components to engines, including using replacement parts from manufacturers’ catalogues
checking induction/exhaust system for leaks
using appropriate tools, equipment and techniques for each task
recording all test and repair activities in accordance with procedures

Knowledge evidence

safe work practices and procedures and use of personal protective equipment (PPE)
principles and terminology of supercharging, filtering, inter and after cooling
performance and operational specifications of the induction and exhaust system
procedures and safety precautions for testing induction/exhaust systems for correct operation
equipment and procedures necessary to test flows, pressures and temperatures associated with induction/exhaust systems
components and applications of supercharging apparatus
maintain induction, exhaust and emission control systems
types of emissions, their relationship to standards and specifications and their effects on the environment
sources of emissions from mobile and stationary plant and equipment
exhaust gas recirculation (EGR) systems
supplementary catalytic reduction (SCR) systems
role of particulate filters, charcoal canisters, fuel evaporative control systems and crankcase ventilation in controlling emissions
supercharging apparatus such as turbo charging equipment
common faults associated with induction/exhaust systems and causes of those faults
appropriate action and procedures for correcting common faults in induction/exhaust systems
component specifications/tolerances and actions to be taken if the components are outside of specification
action to be taken if the components are ‘just’ within specification
measuring instruments to be used to carry out dimensional checks on components
the operation of the apparatus installed to balance fuel injection to boost pressure and control devices installed to prevent excessive turbocharger RPM and/or boost pressure
procedures and safety precautions for removing/fitting components to engines
procedures for recording test and repair activities undertaken on induction/exhaust systems
consequences of air/exhaust leaks on the safe operation of the induction/exhaust system and procedures for testing for leaks in induction/exhaust systems

Questions about assessing MEM27008

What does an assessment tool for MEM27008 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM27008 needs to address all 51 unit components: 4 elements with 19 performance criteria, 10 performance evidence requirements, 22 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 MEM27008?

Auditori pulls the current release of MEM27008 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 MEM27008 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM27008 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 MEM27008, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
