Evidence Required

The Evidence Guide forms an integral part of this Competency Standard Unit and shall be used in conjunction with all components parts of this unit and performed in accordance with the Assessment Guidelines of this Training Package

Overview of Assessment
	Longitudinal competency development approaches to assessment such as Profiling require data to be reliably gathered in a form that can be consistently interpreted over time This approach is best utilised in Apprenticeship programs and reduces assessment intervention It is the Industrys preferred model for apprenticeships However where summative or final assessment is used it is to include the application of the competency in the normal work environment or at a minimum the application of the competency in a realistically simulated work environment It is recognised that in some circumstances assessment in part or full can occur outside the workplace However it must be in accord with Industry and Regulatory policy in this regard
	Methods chosen for a particular assessment will be influenced by various factors These include the extent of the assessment the most effective locations for the assessment activities to take place access to physical resources additional safety measures that may be required and the critical nature of the competencies being assessed
	The critical safety nature of working with electricity electrical equipment gas or any other hazardous substancematerial carries risk in deeming a person competent Hence sources of evidence need to be rich in nature so as to minimise error in judgment
	Activities associated with normal every day work have a bearing on the decision as to how much and how detailed the data gathered will contribute to its richness Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practiced These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments Sample assessment instruments are included for Assessors in the Assessment Guidelines of this Training Package

Critical aspects of evidence required to demonstrate competency in this unit
	Before the critical aspects of evidence are considered all prerequisites shall be met
	Evidence for competence in this unit shall be considered holistically Each element and associated Performance Criteria shall be demonstrated on at least two occasions in accordance with the Assessment Guidelines UEG Evidence shall also comprise
	A representative body of work performance demonstrated within the timeframes typically expected of the discipline work function and industrial environment In particular this shall incorporate evidence that shows a candidate is able to
	Implement Occupational Health and Safety workplace procedures and practices including the use of risk control measures as specified in the Performance Criteria and range
	Apply sustainable energy principles and practices as specified in the Performance Criteria and range
	Demonstrate an understanding of the essential knowledge and associated skills as described in this unit to such an extent that the learners performance outcome is reported in accordance with the preferred approach namely a percentile graded result where required by the regulated environment
	Demonstrate an appropriate level of employability skills
	Conduct work observing the relevant Antidiscrimination legislation regulations polices and workplace procedures

Context of and specific resources for assessment
	This unit should be assessed as it relates to normal work practice using procedures information and resources typical of a workplace This should include
	WHSOHS policy and work procedures and instructions
	Suitable work environment facilities equipment and materials to undertake actual work as prescribed by this Competency Standard Unit
	Appropriate environmental regulation and work practices
	Appropriate organisational requirements
	Appropriate work environment equipment and tools
	These should be part of the formal learningassessment environment
	Assessment of this competency must also be undertaken in either an actual workplace or under a simulated work environment Where simulation is considered a suitable strategy for assessment conditions must be authentic and as far as possible reproduce and replicate the workplace and be consistent with the approved industry simulation policy The resources used for assessment should reflect current industry practices in relation to locating proving and protecting utility assets

Method of assessment
	This Competency Standard Unit shall be assessed by methods given in Volume Part Assessment Guidelines
	Note Competent performance with inherent safe working practices is expected in the Industry to which this Competency Standard Unit applies This requires that the specified required Skills and Knowledge are assessed in a structured environment which is primarily intended for learningassessment and incorporates all necessary equipment and facilities for learners to develop and demonstrate the required skills and knowledge and associated skills described in this unit
