What an assessment for MEAMEC0055 must cover

33 assessable components: 4 elements (16 performance criteria), 3 performance evidence and 11 knowledge evidence requirements, plus 3 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 for shot-peening task

  • 1.1Obtain and interpret process documentation requirements
  • 1.2Prepare shot-peening equipment in accordance with the applicable process

2 Apply shot-peening process to Almen strip

  • 2.1Select and fit the correct Almen strip and set up equipment with the correct stand-off distance and regulated air pressure or spindle speed in accordance with the process documentation
  • 2.2Implement applicable work health and safety (WHS) provisions, including the use of material safety data sheets (MSDSs) and personal protective equipment (PPE)
  • 2.3Apply the process to the Almen strip
  • 2.4Measure the Almen strip distortion to ensure that it is within the specified tolerance
  • 2.5Adjust equipment settings and repeat the Almen strip test when required
  • 2.6Record settings that produce specified Almen strip distortion and present the test strip for inspection

3 Apply shot-peening process to component

  • 3.1Clean and mask the component in accordance with process documentation
  • 3.2Apply shot-peening in accordance with the process documentation using equipment settings derived from Almen test strip and while observing all WHS requirements, including use of MSDSs and PPE
  • 3.3Check the shot peened surface for required density and coverage and re-peen, when required
  • 3.4Check the shot-peened component for cleanliness to ensure that all contaminants have been removed in accordance with the process documentation

4 Complete shot-peening task

  • 4.1Record task completion in accordance with standard enterprise procedures
  • 4.2Present shot-peened component for inspection, along with Almen test strip and completed documentation
  • 4.3Tag, seal and pack the component, where applicable and in accordance with specified procedures
  • 4.4Dispose of waste shot peening media in accordance with procedures

Performance evidence

  • shot-peen applications on more than one aircraft component
  • apply correct stand-off distances for either of the following: nozzle distance from surface for air pressure shot peening processes, or spindle distance from job for rotor shot peening
  • regulate air pressure or spindle speed through either the specified air pressure applied to the shot nozzle or the specified revolutions per minute (r.p.m.) of the spindle in the rotor peening process

Knowledge evidence

  • how to obtain relevant material safety data sheets (MSDSs)
  • the correct use of personal protective equipment (PPE)
  • work health and safety (WHS) procedures
  • the reasons for shot peening
  • the types of aircraft component and the materials that are shot peened
  • shot-peening equipment and processes applicable to aircraft components, including: air pressure or rotor propulsion of shot; fixed or portable shot peen units; the uses of different types of shot peening media
  • the use of process documentation
  • the types of Almen test strips and their uses
  • setting up and calibrating equipment for use
  • preparation of surfaces for peening and cleaning after peening
  • environmental requirements associated with disposal of used media

Foundation skills

  • Reading skills: Reading skills to interpret maintenance documentation and procedures.
  • Writing skills: Writing skills to complete maintenance documentation.
  • Numeracy skills: Numeracy skills to interpret and communicate technical information and to measure and adjust equipment within specified tolerances.

Questions about assessing MEAMEC0055

What does an assessment tool for MEAMEC0055 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEAMEC0055 needs to address all 33 unit components: 4 elements with 16 performance criteria, 3 performance evidence requirements, 11 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 MEAMEC0055?

Auditori pulls the current release of MEAMEC0055 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 MEAMEC0055 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEAMEC0055 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 MEAMEC0055, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
