Unit of Competency RIINHB329 - Conduct sonic drilling operations
Description
Employability Skills
Learning Outcomes and Application This unit describes the skills and knowledge required to conduct sonic drilling. It prepares learners to drill using sonic methods, including casing off unconsolidated formations and retrieving core.It applies to those working in driller roles. They generally perform tasks involving a broad range of skilled applications in a wide variety of contexts, which may involve some discretion and judgement in selecting equipment, services and contingency measures.Licensing, legislative and certification requirements that apply to this unit can vary between states, territories, and industry sectors. Users must check requirements with relevant body before applying the unit.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Mandatory conditions for assessment of this unit are stipulated below. The assessment must:

include access to:

personal protective equipment

equipment required to conduct sonic drilling

be conducted in a safe environment; and,

be assessed in the context of this sector's work environment; and,

be assessed in compliance with relevant legislation/regulation and using policies, procedures and processes directly related to the industry sector for which it is being assessed; and,

confirm consistent performance can be applied in a range of relevant workplace circumstances.

Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated work environment* provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Assessor requirements

Assessors must be able to clearly demonstrate current and relevant industry knowledge and experience to satisfy the mandatory regulatory standards as set out in the Standards for Registered Training Organisations (RTOs) 2015/Australian Quality Training Framework mandatory requirements for assessors current at the time of assessment and any relevant licensing and certification requirements. This includes:

vocational competencies at least to the level being delivered and assessed

current industry skills directly relevant to the training and assessment being provided

current knowledge and skills in vocational training and learning that informs their training and assessment

formal relevant qualifications in training and assessment

having knowledge of and/or experience using the latest techniques and processes

possessing the required level of RII training product knowledge

having an understanding and knowledge of legislation and regulations relevant to the industry and to employment and workplaces

demonstrating the performance evidence, and knowledge evidence outlined in this unit of competency, and

the minimum years of current** work experience after competency has been obtained as specified below in an industry sector relevant to the outcomes of the unit.

It is also acceptable for the appropriately qualified assessor to work with an industry expert to conduct assessment together and for the industry expert to be involved in the assessment judgement. The industry expert must have current industry skills directly relevant to the training and assessment being provided. This means the industry subject matter expert must demonstrate skills and knowledge from the minimum years of current work experience after competency has been obtained as specified below, including time spent in roles related to the unit being assessed:

Industry sector

Other sectors

Where this unit is being assessed outside of the resources and infrastructure sectors assessor and/or industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no industry standard is specified should comply with any relevant regulation.

*Guidance on simulated environments has been stipulated in the RII implementation guide located on VETNet.

**Assessors can demonstrate current work experience through employment within industry in a role relevant to the outcomes of the unit; or, for external assessors this can be demonstrated through exposure to industry by conducting a minimum number of site assessments as determined by the relevant industry sector, across various locations.

*** While a unit of competency does not have an AQF level, where a unit is being delivered outside of a qualification the first numeric character in the unit code should be considered as the AQF indicator level for assessment purposes.
