The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the Performance Criteria, Required Skills and Knowledge and the Range Statement of this unit and include evidence of the following:

knowledge of the requirements, procedures and instructions that are to apply in undertaking blast hole drilling operations

implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes of blast hole drilling operations

working with others to plan, prepare and execute blast hole drilling operations

operational plans which reflect the requirements of these blast hole drilling operations and are capable of achieving all of their required outcomes

resource plans which have made available adequate resources for the safe, effective and efficient execution of blast hole drilling operations

provision of clear and timely instruction, advice and supervision by the individual of those involved in the undertaking of these blast hole drilling operations

evidence of the consistent successful completion of blast hole drilling operations under their supervision

Context of and specific resources for assessment

This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.

The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.

Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.

Aboriginal people and other people from a non English speaking background may have second language issues.

Assessment of this competency requires typical resources normally used in a resources and infrastructure sector environment. Selection and use of resources for particular worksites may differ due to the site circumstances.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

Method of assessment

This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:

written and/or oral assessment of the candidate's required knowledge

observed, documented and/or first hand testimonial evidence of the candidate's:

implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes of blast hole drilling operations

operational plans which reflect the requirements of blast hole drilling operations and are capable of achieving all of their required outcomes

resource plans which have made available adequate resources for the safe, effective and efficient execution of blast hole drilling operations

consistent successful completion of blast hole drilling operations under their supervision

first hand testimonial evidence of the candidate's:

working with others to plan, prepare and execute blast hole drilling operations

supervising and providing clear and timely instruction and advice to those involved in the undertaking blast hole drilling operations
