What an assessment for PMAOPS314 must cover

46 assessable components: 4 elements (27 performance criteria), 1 performance evidence and 13 knowledge evidence requirements, plus 5 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 Operate compressor system according to procedures

  • 1.1Receive and give shift handover
  • 1.2Communicate with personnel to identify and coordinate work requirements
  • 1.3Identify, control and report process system hazards
  • 1.4Check for recent work undertaken on compressor system and address outstanding and incomplete work
  • 1.5Check operational status of process system
  • 1.6Perform routine checks and complete logs and paperwork, taking action on unexpected readings
  • 1.7Adjust process system according to agreed operational parameters

2 Identify and respond to abnormal situations during operation

  • 2.1Monitor compressor system and its component plant items frequently and critically throughout shift using own senses, and measured and indicated data
  • 2.2Monitor field data and instrumentation to ensure that product remains on specification
  • 2.3Identify impacts of changes upstream and downstream
  • 2.4Identify actual and developing situations that may require action
  • 2.5Take action to remedy abnormal situations according to operating procedures
  • 2.6Complete required documents outlining abnormal situation management and corrective action taken

3 Shut down and prepare compressor system for maintenance

  • 3.1Prepare process system to be shut down according to operating procedures
  • 3.2Complete pre-shutdown checks according to operating procedures
  • 3.3Shut down process system according to operating procedures
  • 3.4Identify, control and report shutdown hazards
  • 3.5Monitor shutdown and identify abnormal situations that may require action
  • 3.6Take action to remedy abnormal situations according to operating procedures
  • 3.7Shut down and changeover duty and standby equipment according to operating procedures
  • 3.8Isolate process system from energy sources

4 Prepare and start up compressor system

  • 4.1De-isolate and prepare process system to be returned to standby or service
  • 4.2Complete pre-start checks according to operating procedures
  • 4.3Start up compressor process system according to operating procedures
  • 4.4Identify, control and report startup hazards
  • 4.5Monitor startup and identify abnormal situations that may require action
  • 4.6Take action to remedy abnormal situations according to operating procedures

Performance evidence

  • at least 2 times, each in a separate work context.

Knowledge evidence

  • all items on a schematic of the compressor system, including: type of compressor, the component plant items and their functions
  • principles of operation of plant and equipment
  • functions of major components and troubleshooting techniques
  • interactions between plant items and processes
  • operating parameters and integrity limits, and product specifications and tolerances including temperature, pressure and flow
  • procedures for starting, stopping, operating, controlling and isolating the system
  • methods of changing flow rate and specifications, and the advantages and disadvantages of each
  • impact of external factors (including variations in weather)
  • emergency shutdown procedures
  • physics to the level of being able to provide an overview of the science of the compressor process
  • compressor system abnormal situations and required action, including but not limited to: process gas variations, instrument failure and wrong reading, electrical failure, mechanical failure, operational problem, surging, control of temperature and pressure, variations in feed, vibration
  • hierarchy of control
  • compressor system hazards: possible causes, potential consequences, appropriate risk controls, reporting and escalation procedures.

Foundation skills

  • Learning skills: to follow instructions, monitor process and select appropriate procedure.
  • Reading skills: to follow written procedures and documentation.
  • Writing skills: to complete workplace documentation.
  • Oral communication skills: to liaise and coordinate with team members and the control-room operator.
  • Numeracy skills: to monitor field data, instrumentation and process parameters.

Questions about assessing PMAOPS314

What does an assessment tool for PMAOPS314 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for PMAOPS314 needs to address all 46 unit components: 4 elements with 27 performance criteria, 1 performance evidence requirements, 13 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 PMAOPS314?

Auditori pulls the current release of PMAOPS314 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 PMAOPS314 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing PMAOPS314 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 PMAOPS314, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
