What an assessment for MARC049 must cover

43 assessable components: 3 elements (12 performance criteria), 9 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 Prepare for operation

1.1Risks to self, others and the environment are identified according to organisational procedures
1.2Routine pre-operational checks of electrical systems are completed prior to use according to manufacturer specifications and organisational procedures

2 Operate electrical systems

2.1Suitable personal protective equipment (PPE) is selected and used according to organisational procedures
2.2Electrical systems are operated in a safe and controlled manner
2.3Performance of DC and AC electrical systems is monitored
2.4AC electrical demand is monitored and additional generators are paralleled or disconnected, as required
2.5Ship-to-shore electrical supply is connected and disconnected, when required, following established practices and organisational procedures
2.6Faults or malfunctions are identified and reported according to organisational procedures
2.7Faults or malfunctions are rectified and corrective actions are taken and recorded according to organisational procedures
2.8Procedures to be undertaken in emergencies are recognised and implemented

3 Complete operations and check electrical systems

3.1Shutdown procedures are conducted according to manufacturer instructions and organisational procedures
3.2Operational records are completed according to organisational procedures

Performance evidence

carrying out necessary calculations associated with managing electrical systems, including: adding resistors in series and parallel, and calculating current; battery ampere-hours and efficiency; series and parallel configuration of battery supply
connecting to shore power

relevant problems that may occur with electrical systems and appropriate preventative and remedial actions to be taken
relevant sections of state and territory maritime regulations, Marine Order 505 and Uniform Shipping Laws (USL) Code
relevant work health and safety (WHS)/occupational health and safety (OHS) legislation and policies
safety devices fitted to switchboard and other electrical systems, including fuses and circuit breakers

Questions about assessing MARC049

What does an assessment tool for MARC049 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MARC049 needs to address all 43 unit components: 3 elements with 12 performance criteria, 9 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 MARC049?

Auditori pulls the current release of MARC049 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 MARC049 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MARC049 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 MARC049, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
