Evidence Guide

EVIDENCE GUIDE 

9)  The Evidence Guide forms an integral part of this Unit and shall be used in conjunction with all components parts of the unit and performed in accordance with the Assessment Guidelines of this Training Package.

Overview of Assessment 

9.1) 

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 Industry s 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 regulatory policy in this regard.

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 substance/material 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 for Assessors in the Assessment Guidelines of this Training Package.

Critical aspects of evidence required to demonstrate competency in this unit 

9.2) 

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 UEG11 . 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

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

  • Demonstrate an understanding of the essential knowledge and associated skills as described in this unit to such an extent that the learner s performance outcome is reported in accordance with the preferred approach; namely a percentile graded result, where required by the regulated environment

  • Demonstrate an appropriate level of employability skills

  • Conduct work observing the relevant anti-discrimination legislation, regulations, polices and workplace procedures

  • Demonstrate performance across a representative range of contexts from the prescribed items below.

Context of and specific resources for assessment 

9.3) 

This unit contains Employability Skills

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 Competency Standard Unit.

  • Appropriate environmental regulation and work practices.

  • Appropriate organisational requirements.

  • Appropriate work environment, equipment and tools.

In addition to the resources listed above, in Context of and specific resources for assessment, evidence should show demonstrated competency in commission/decommissioning gas transmission pipelines.

Method of assessment 

9.4) 

This Competency Standard Unit shall be assessed by methods given in Volume 1, Part 3 Assessment Guidelines .

Note: Competent performance with inherent safe working practices is expected in the Industry to which this Competency Standard Unit applies.
