EVIDENCE GUIDE
9) 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
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 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 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 - UET09". 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 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; 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:


Range of tools/equipment/materials/procedures/workplaces/other variables


Group No
The minimum number of items on which skill is to be demonstrated
Item List


A
Demonstrate at least three (3) coordinate of multiple simultaneous system manipulations that encompass the following:
LV distribution network
LV network manipulation to control loading on equipment
Transformers with LV windings (if applicable to enterprise equipment)
LV busbars
LV isolators
LV switchgear (applicable to enterprise equipment).


B
All of the following:
Writing switching instructions
Checking and review switching instructions
Coordinating multiple simultaneous switching instructions
Confirm line loading
Preparing and authorising LV distribution switching programs
Coordinate multiple switching processes
Coordinate the status of all access permits/authorities on LV network equipment relevant to the scope
Ensure network plant operates within design and regulatory requirements on a real time basis
Application and administration of SCADA or equivalent.
Analysis, diagnosis and reporting of system failure
Calculate and analyse paralleling conditions on the interconnected LV system.


C
Prepare, write and check switching sheets to:
Manage load
Manage voltage
Minimise loss
Maximise system reliability
Allow safe network access for maintenance activities
Allow safe network access for construction activities
Validating fault reports arising from system disturbances.


D
At least one occasion
Dealing with an unplanned event by drawing on essential knowledge and associated skills to provide appropriate solutions incorporated in the holistic assessment with the above listed items.
Context of and specific resources for assessment
9.3)
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 the coordination of LV distribution network demand.
Note:
Access will be needed to: relevant modelling tools, drawings, computerised electrical plant control and monitoring facilities and enterprise operational policies, procedures and work practices.

In addition to the resources listed above, in Context of and specific resources for assessment, evidence should show demonstrated competency working in realistic environment and a variety of conditions.
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 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 learning/assessment 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
9.5)
There are no concurrent assessment recommendations for this unit.
