What an assessment for RIIOGD203F must cover

44 assessable components: 6 elements (29 performance criteria), 5 performance evidence and 7 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 Plan and prepare for operations

1.1Obtain, interpret and confirm work requirements

1.3Identify and minimise environmental issues and potential hazards, and assess and address risks within scope of own role and according to workplace procedures
1.4Select the personal protective equipment required for work activity
1.5Communicate with other personnel on site as required and confirm briefings and handover details are communicated and received
1.6Assess geographic layout and confirm type of fluid system in use is suitable
1.7Assess operation of mud mixers, dump valves and equalising valves
1.8Identify and locate mud pump and discharge system

2 Establish operational requirements

2.1Clarify difficulties in carrying out instructions with relevant personnel
2.2Confirm availability and status of necessary permits to work
2.3Confirm availability of necessary third party utilities
2.4Confirm availability of required quantities and type of consumables
2.5Identify errors, omissions and shortages and take remedial action as required within functional responsibility

3 Select and test equipment

3.1Identify and select equipment required for work activities
3.2Identify defects in equipment and take remedial action as required within functional responsibility
3.3Confirm equipment is functional and fit for purpose and environment in which it will be used
3.4Lubricate fluid circulation components

4 Prepare drilling fluids

4.1Confirm availability of sufficient quantities and types of fluids against operational requirements
4.2Confirm tanks and mixing equipment are clean and free from contamination according to instructions
4.3Mix and treat fluids to specification
4.4Obtain, label in writing and store samples according to workplace procedures and operational requirements

5 Pump drilling fluids and record data

5.1Confirm recording and monitoring devices are pre-set to required parameters
5.2Operate equipment according to safety and operational requirements
5.3Assist with weighing and measuring viscosity of samples and record details
5.4Record in writing data at scheduled times and frequencies according to operational requirements

6 Conduct hopper system operating procedures

6.1Identify type of hopper system
6.2Operate and maintain hopper system and associated components
6.3Measure, calculate and log in writing mud properties
6.4Recognise, record and report changes in returns of drilling fluid and pit volumes

Performance evidence

prepare and operate drilling fluid systems on at least two occasions, including: maintaining and operating mud mixers, dump valves and equalising valves in the mud pits system; adding mud materials to mud systems as instructed; taking and recording mud properties readings.
locate and apply documentation required for preparing and operating drilling fluid systems
conform to safe working practices and operational requirements
implement the requirements, procedures and techniques for preparing and operating drilling fluid systems, including: operating and maintaining all mud treatment units; interpreting and acting on additional flow in the mud returns or an increase in mud pit volume; lubricating fluid circulation components
work with others to preparing and operating drilling fluid systems tasks that meet required outcomes, including: organising work activities to meet task requirements; communicating with others to receive and clarify work instructions.

Knowledge evidence

key policies, procedures and established requirements for preparing and operating drilling fluid systems, including those for: work health and safety and individual obligations; operating and maintaining equipment including hopper system; rig maintenance; chemical handling; preparing and pumping drilling fluids; complying with safety data sheets (SDS)
principles of the systems, equipment and their relationship to other plant
rig safety and emergency procedures
the layout of mud circulating, mixing and suction systems
non-routine drilling operations
compliance with personnel and rig management procedures layout of shaker, degasser and settling pits, and sand traps
key factors affecting work activities described in performance evidence above, including: fluid types and composition; geographic layout; type of fluid system in use; hazards relevant to preparing and operating drilling fluid systems; drilling team roles and objectives.

Foundation skills

Numeracy: Interprets numerical information relating to fluid quantity, weight, viscosity, mix specifications and pit volumes
Reading: Identifies and interprets information from workplace procedures and documentation
Self-management: Monitors and minimises own exposure to worksite hazards during activities

Questions about assessing RIIOGD203F

What does an assessment tool for RIIOGD203F need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for RIIOGD203F needs to address all 44 unit components: 6 elements with 29 performance criteria, 5 performance evidence requirements, 7 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 RIIOGD203F?

Auditori pulls the current release of RIIOGD203F 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 RIIOGD203F — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing RIIOGD203F 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 RIIOGD203F, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
