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 competency standard 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 component 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 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 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 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 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 shall be demonstrated on at least two occasions in accordance with the Assessment Guidelines UET Evidence shall also comprise

A representative body of Performance Criteria 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 and

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

Demonstrate an understanding of the essential knowledge and associated skills 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

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 maintenance of traction bonds

In addition to the resources listed above in context of and specific resources for assessment evidence should show demonstrated competency working below ground in limited spaces with different structuralconstruction types and method and in a variety of environments

Method of assessment

This Competency Standard Unit shall be assessed by methods given in Volume Part Assessment Guidelines

Note

Competent performance with inherent safe working practices is expected in the Transmission Distribution and Rail Traction Industry 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 associated skills described in this unit

Concurrent assessment and relationship with other units

There are no concurrent assessment recommendations for this unit


Range Statement

10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance.

This Competency Standard Unit shall be demonstrated in relation to the maintenance of the temporary and permanent traction bonds and bonding cables according to work plans.

Maintenance may include the removal, repair and replacement of bonds and bonding cables, conductors and associated hardware.

Maintenance includes the carrying out of diagnostics and tests on structures, conductors, equipment, spark gaps, systems as well as the removal, repair and replacement of bonding cables, spark gaps, conductors, and associated hardware and returning such to operational service.

Earthing and bonding systems may be permanent or temporary.

Types of conductors may include steel, steel rail, copper, aluminium and steel, bare and sheathed cables, single core, stranded and flexible.

Cables may be surfaced mounted, buried and enclosed.

Permanent jointing and terminating materials include polymeric tape materials, polymeric heat shrink and covering materials, exothermic welds, crimped and bolted connections.

Temporary terminating components include screwed and clipped earth/rail/conductor clamps.
