Evidence Required

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 for conducting raise boring

implementation of requirements procedures and techniques for the safe effective and efficient conducting of raise boring

working with others to undertake and complete raise boring that meets all of the required outcomes

consistent timely completion of raise boring that safely effectively and efficiently meets the required outcomes

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 the work environment Selection and use of resources for particular worksites may differ due to site circumstances

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

Access must be provided to appropriate learning andor 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 andor oral assessment of the candidates required knowledge

observed documented andor first hand testimonial evidence of the candidates

implementation of appropriate requirement procedures and techniques for the safe effective and efficient achievement of required outcomes

consistently achieving the required outcomes

first hand testimonial evidence of the candidates

working with others to undertake and complete the raise boring
