Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for this Training Package

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

Solving problems in electronic and digital equipment as described in and including

A

Using methodical problem solving methods

B

Taking and recording measurements correctly and accurately using relevant measuring equipment

C

Deducing equipment behaviour correctly and accurately

D

Providing written justification for the solutions to problems

E

Dealing with unplanned events by drawing on essential knowledge and skills to provide appropriate solutions incorporated in a 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 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 solving basic problems electronic and digital equipment

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

There are no concurrent assessment recommendations for this unit
