Evidence Required

This provides essential advice for assessment of the unit It must be read in conjunction with the performance criteria and the range statement of the unit and the Training Package Assessment Guidelines The Evidence Guide forms an integral part of this unit It must be used in conjunction with all parts of the 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 industrypreferred 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 accordance with industry and regulatory policy 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 Sources of evidence need to be rich in nature to minimise error in judgment Activities associated with normal everyday 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 practised 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 must 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 UEE 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 statement Apply sustainable energy principles and practices as specified in the performance criteria and range statement Demonstrate an understanding of the essential knowledge and associated skills as described in this unit It may be required by some jurisdictions that RTOs provide a percentile graded result for the purpose of regulatory or licensing requirements Demonstrate an appropriate level of skills enabling employment Conduct work observing the relevant Anti Discrimination legislation regulations polices and workplace procedures Demonstrated consistent performance across a representative range of contexts from the prescribed items below Produce detailed electrical drawings as described in Range and including A Producing a variety of detailed electrical drawings B Producing drawing sets C Producing drafting documentation D Interpreting and using technical data and specifications E Selecting components and materials F Using advanced computeraided systems and commands G Using relevant drafting peripheral systems equipment and tools to develop detailed drawings H Digitising and scanning draftingdrawings products I Applying knowledge of electrical equipment design drawing methods techniques procedures and protocols and documenting design J Applying knowledge related to storing and retrieving data and producing related documentation for presentations K Presenting preliminary and final drafts for verification

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 OHS policy and work procedures and instructions Suitable work environment facilities equipment and materials to undertake actual work as prescribed in this unit These should be used in the formal learningassessment environment Note Where simulation is considered a suitable strategy for assessment conditions for assessment 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 producing detailed electrical drawings

Method of assessment

This 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 unit applies This requires that the specified essential knowledge and associated skills 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 essential knowledge and skills described in this unit

Concurrent assessment and relationship with other units
	For optimisation of training and assessment effort competency development in this unit may be arranged concurrently with units covering the use of detailed electrical drawings
