Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.

A person who demonstrates competency in this unit must be able to:

comply with WHS requirements and safe work practices

ensure electrical and mechanical integrity of components and system is maintained when performing tests

check traction motor performance against manufacturer specifications

diagnose and replace, repair or adjust traction motor as required to correct deficiencies

complete relevant documentation for the diagnosis and repair of the traction motor.

Context of, and specific resources for assessment

Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting.

Assessment is to occur:

using standard workplace practices and procedures

following safety requirements

applying environmental constraints.

Assessment is to comply with relevant:

regulatory requirements

Australian standards

industry codes of practice.

Competency is to be assessed using a BEV that uses HV and low voltage (LV) AC/DC electrical systems. Where simulation is used, an operational BEV must be included in the simulation.

The following resources must be made available for the assessment of this unit:

appropriate PPE

a BEV

manufacturer specifications for the BEV

testing equipment

full range of essential tools and equipment

workplace documentation.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge.

Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application.

Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients.

Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
