What an assessment for AURTTM008 must cover

76 assessable components: 4 elements (15 performance criteria), 4 performance evidence and 51 knowledge evidence requirements, plus 6 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 Prepare to dismantle engine block and sub-assembly

1.1Job requirements are determined from workplace instructions
1.2Engine block and sub assembly dismantling information is sourced and interpreted
1.3Tools and measuring equipment are selected and checked for serviceability
1.4Hazards associated with the work are identified and risks are managed
1.5Engine is set up for dismantling using appropriate lifting equipment and avoiding fluid spillage according to safety and environmental requirements
1.6Engine block and sub-assembly are cleaned according to safety and environmental procedures and relevant Australian standards, and positions of auxiliary equipment are recorded, including photographic evidence

2 Dismantle engine block and sub-assembly

2.1Covers and ancillary components are removed, cleaned and stored according to workshop procedures
2.2Engine block and sub-assembly are dismantled according to safety requirements and laid out in a logical order using approved methods, tools and equipment
2.3Component parts are cleaned using appropriate cleaning agents for the type of material and kept in a logical order in preparation for evaluation

3 Determine repair procedures

3.1Engine block and sub-assembly are inspected, measured and tested against manufacturer specifications and tolerances and according to workplace procedures and safety requirements
3.2Engine block and sub-assembly are evaluated and repair requirements are determined and reported according to workplace procedures

4 Complete dismantle and evaluation processes

4.1Final inspection is made to ensure finished work complies with workplace requirements
4.2Bright surfaces are treated with rust prevention solution and engine block and sub-assembly are prepared for further process or storage according to workplace procedures
4.3Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
4.4Workplace documentation is processed according to workplace procedures

Foundation skills

Learning skills: locate appropriate sources of information efficiently.
Reading skills: identify and interpret engine component specifications from workshop literature interpret safe operating procedures for engine component rebuild machinery from operating manuals and signs.
Writing skills: legibly and accurately fill out workplace documentation when making recommendations.
Numeracy skills: interpret numerical information in manufacturer specifications, workshop literature, and machinery dials, gauges and computer readouts use basic mathematical operations, including addition and subtraction, to: convert metric dimensions to imperial, and imperial dimensions to metric calculate tolerances and clearances.
Planning and organising skills: select best tooling option for the work and sequence components to reduce time and material wastage.
Technology skills: use metric and imperial precision measuring equipment.

Questions about assessing AURTTM008

What does an assessment tool for AURTTM008 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURTTM008 needs to address all 76 unit components: 4 elements with 15 performance criteria, 4 performance evidence requirements, 51 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 AURTTM008?

Auditori pulls the current release of AURTTM008 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 AURTTM008 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURTTM008 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 AURTTM008, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
