Evidence Required

This provides essential advice for assessment of the competency standard unit and 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 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

Longitude 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 Industry 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 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 practised These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments Sample assessment instruments are included 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 UEP 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 Essential Knowledge and Associated Skills of this unit Demonstrate an appropriate level of employability skills Conduct work observing the relevant AntiDiscrimination legislation regulations polices and workplace procedure Demonstrated performance across a representative range of contexts from the prescribed items below The knowledge and application of relevant sections of occupational health and safety legislation statutory legislation enterprisesite safety procedures enterprisesite standard operating procedures and safe operating principles enterprisesite emergency procedures The knowledge of the principles of NOx generation during the combustion process within fossil fuelled boilers and gas turbines The knowledge of principles and techniques of operation of NOx emission control plant and equipment The knowledge of system components and the manner in which these components interact with other plant and equipment The knowledge of operational testing of plant The ability to prepare and plan work The ability to prepare plantequipment for operation The ability to operate and monitor plantequipment in accordance with enterprisesite standard operating procedures and safe operating principles The ability to analyse plant faults Dealing with an unplanned event by drawing on essential knowledge and skills to provide appropriate solutions incorporated in the holistic assessment with the above listed items

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 by this unit Competency Standards should be assessed in the workplace or simulated workplace and under the normal range of workplace conditions Assessment of this unit will be supported with documentary evidence by means of endorsement stating type and application of work In addition to the resources listed above in Context of assessment evidence should show competency working in limited spaces with different types of plant and equipment as well as different structuralconstruction types and methods and in a variety of environments
