This provides essential advice for assessment of the 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 unit It must 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 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 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 Sources of evidence need to be rich in nature to minimise error in judgment

Activities associated with normal everyday work influence decisions about howhow much 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 shall be met

Evidence for competence in this unit shall be considered holistically Each element and associated performance criteria must be demonstrated on at least two occasions in accordance with the Assessment Guidelines UEE Evidence shall also comprise

Evidence for competence in this unit shall be considered holistically. Each element and associated performance criteria must be demonstrated on at least two occasions in accordance with the 'Assessment Guidelines - UEE07 '. Evidence shall also comprise:

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 also be part of 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 testing installations in hazardous areas

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 assessment in a structured environment primarily intended for learningassessment which incorporates all necessary equipment and facilities for learners to develop and demonstrate the essential knowledge and skills described in this unit
