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 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

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 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 practiced 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

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 for the UEP Training Package

On at least two (2) occasions, In accordance with the "Assessment Guidelines” for the UEP12 Training Package.

Evidence shall also comprise

A representative body of work performance demonstrated within the timeframe 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 and

Apply sustainable energy principles and practices as specified in the Performance Criteria and range and

Demonstrate an understanding of the required skills and knowledge 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 and

Demonstrate an appropriate level of employability skills and

Conduct work observing the relevant Anti Discrimination legislation regulations policies and workplace procedures and

Demonstrated performance across a representative range of contexts from the prescribed items below

A

Perform a firmware upgrade

Perform a software reload

B

Interpret fault code and similar data produced by monitoring systems

C

Connect data communications cables to control systems and equipment

Interrogate control systems using rd party software systems

D

Confirm correct output signals from sensors and encoders

E

Deal with an unplanned event by drawing on essential knowledge and skills to provide appropriate solutions

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

These should be used in the formal learningassessment environment

Note

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

Diagnose and repair faults in wind turbine generator control systems

Method of assessment

This unit shall be assessed by methods given in 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

There are no recommended concurrent assessments with this unit however in some cases efficiencies may be gained in terms of learning and assessment effort being concurrently managed with allied competency standard units where listed
