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, the Range Statement and the Assessment Guidelines for the Training Package.

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

Evidence of the following is essential:

confirms the site and the meter

checks meter condition

replaces components as required

documents the maintenance.

Context of and specific resources for assessment

Assessment must ensure:

access to a range of meters and installation sites

access to organisational documentation

observance of OHS guidelines.

A range of assessment methods should be used to assess knowledge. The following examples are appropriate for this unit:

Written questions

Oral questions on the job during the maintenance process

Written Reports including Asset Condition Checklist, Meter Condition Report

Third party reports from workplace supervisors.

A range of assessment methods should be used to assess skills. The following examples are appropriate for this unit:

Demonstrations of meter maintenance in a workplace environment

Written Reports including Asset Condition Checklist, Meter Condition Report

Third party reports from workplace supervisors.

Assessment should be based on evidence which has been gathered from a number of meter installations in a range of conditions which reflect a predictable variety of routine requirements and the range of variables, as well as which allow the potential for applying knowledge and skills in some conditions which require problem solving and contingency responses.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

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

Validity and sufficiency of evidence requires that:

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice

a decision of competence only taken at the point when the assessor has complete confidence in the person's competence over time and in various contexts

all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence

where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit.

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level, required for this unit.

Required skills:
