What an assessment for RIINHB311E must cover

42 assessable components: 3 elements (16 performance criteria), 18 performance evidence and 4 knowledge evidence requirements, plus 4 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 mud rotary drilling

1.1Obtain, interpret and confirm work requirements
1.2Access, interpret and apply mud rotary drilling documentation and confirm work activity is compliant
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 and wear personal protective equipment required for work activities
1.5Communicate with other personnel at site according to work requirements and confirm briefings and handover details are communicated and received

2 Operate mud rotary drill in line with established requirements

2.1Carry out prestart and start-up procedures according to manufacturer specifications and workplace procedures
2.2Make up drill fluid according to work requirements
2.3Set up drill string, bits, rods and casings required to complete work activity
2.4Check, adjust and maintain fluid recirculation systems according to work requirements
2.5Install collar and seal according to work requirements
2.6Operate equipment and adjust parameters to suit conditions of the hole
2.7Install casing, grout and screens to correct zones according to work requirements
2.8Identify problems or faults and rectify or report within scope of own responsibility and according to workplace procedures

3 Complete equipment shut down and maintenance activities

3.1Shut down and secure equipment in line with workplace procedures
3.2Follow maintenance schedule according to work requirements
3.3Complete and file or distribute documentation for drilling operations and equipment according to workplace procedures

Performance evidence

conduct mud rotary drilling on at least two occasions, including:
planning and preparing for mud rotary drilling, by: developing a work plan for a hole, outlining: environmental practice, health and safety considerations, target depth, construction materials to be used, equipment to be used, mud design, grouting if required
conducting pre-start and shutdown checks
making up and checking drill string and down hole assembly for wear, gauge and damaged threads to ensure components are in suitable condition
operating mud rotary drill, including: designing and adjusting mud system to suit geological conditions and changes to conditions during drilling, including: lost circulation, water supply, flow rates, fluid cleaning, hole stability
conducting sampling to confirm drilling fluids are suitable for application by testing: density, viscosity, pH levels, velocity, pressure control, weight control, filtration levels
monitoring and adjusting up hole velocity as required
installing collar casing and seal
adjusting feed and rotation as required
installing production casings, screens and grout if required
disposing of drill fluids no longer required
conducting routine checks and performing maintenance.
locate and apply relevant documentation, policies and procedures
identify and control any hazardous conditions and contaminants
apply solutions to identified problems, including if applicable: significant drilling operational issues including unexpected geology, loss circulation zones, swelling/shales, weight/pressure control
read, interpret and apply safety data sheets (SDS) for handling hazardous materials
communicate with clients, co-workers and management to receive and clarify work instructions and coordinate work activities prior to commencing
comply with written and verbal reporting requirements and procedures associated with mud rotary drilling operations.

Knowledge evidence

key policies, procedures and established requirements for conducting mud rotary drilling, including those for: workplace health and safety, emergencies, environmental practice, set up and installation of drilling equipment and materials, processes for mud mixing and conditioning, maintenance and repair
basic geological data
lag time and up hole velocity
key factors affecting work activities described in performance evidence above, including: types of mud and water delivery pumps and their applications, types of formations and effects on drilling fluids, types of fluids, including properties and functions of fluids, types of bits, rods and casings and their functions.

Foundation skills

Reading: Identifies and interprets information from workplace procedures, policies and documentation
Numeracy: Identifies and comprehends relevant mathematical information in relation to operating mud rotary drills and fluid systems
Writing: Produces and completes workplace reports using appropriate vocabulary, grammatical structures and conventions
Oral communication: Uses listening and questioning to clarify and confirm understanding

Questions about assessing RIINHB311E

What does an assessment tool for RIINHB311E need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for RIINHB311E needs to address all 42 unit components: 3 elements with 16 performance criteria, 18 performance evidence requirements, 4 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 RIINHB311E?

Auditori pulls the current release of RIINHB311E 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 RIINHB311E — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing RIINHB311E 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 RIINHB311E, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
