What an assessment for PMAOPS231 must cover

36 assessable components: 4 elements (21 performance criteria), 7 performance evidence and 8 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.

Performance evidence

start up, monitor and adjust injection pumps to maintain odour to specifications
store, handle, transfer and dispose of odourant waste in accordance with regulatory requirements and safety data sheets (SDS)
apply shutdown and emergency procedures
recognise and take specified action on early warning signs of equipment/processes needing attention or with potential problems
isolate and de-isolate equipment
identify hazards and apply hazard control procedures
distinguish between causes of problems/alarm/fault indications, including:  process gas variations  instrument failure/wrong readings  electrical failures  mechanical failures  operational problems.

Knowledge evidence

gas odourisation systems and their component functions
principles of operation of plant/equipment
physics and chemistry relevant to the process unit and the materials processed
nature/condition of materials entering and leaving each stage of the process
process parameters and limits, e.g. temperature, pressure and flow
routine problems, faults, their symptoms and resolution
correct methods of starting, stopping, operating and controlling process
hazards that may arise in the job/work environment, and:  their possible causes  potential consequences  appropriate risk controls.

Questions about assessing PMAOPS231

What does an assessment tool for PMAOPS231 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for PMAOPS231 needs to address all 36 unit components: 4 elements with 21 performance criteria, 7 performance evidence requirements, 8 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 PMAOPS231?

Auditori pulls the current release of PMAOPS231 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 PMAOPS231 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing PMAOPS231 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 PMAOPS231, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
