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

Competency must be demonstrated in the ability to perform consistently at the required standard for any class of liquid measuring instrument listed in the Range Statement.

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

Assessors should ensure that candidates can:

identify, access and apply test procedures

identify and use suitable reference standards

evaluate and adjust the impact of the operating environment on the performance of the instrument

analyse test results to determine the instrument's suitability for verification (trade use)

identify the scope of a verifier performance audit and assess results with expected outcomes

audit the performance of verifiers of liquid measuring instruments

identify and implement additional inspection strategies for non-instrument related breaches of national measurement legislation

recognise and act on non-compliance

maintain the security and confidentiality of data in accordance with organisational and regulatory requirements

report results in the required formats and expected timeframe.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

MSATMREF301A Use and maintain reference standards.

Resources may include:

liquid measuring instruments using volume measures, test equipment and reference standards

safety equipment

computer and relevant software and/or organisation information management system

Certificates of Approval for instruments

relevant legislative and organisational procedures.

Method of assessment

The following assessment methods are suggested:

questions to assess understanding of relevant procedures, licensing requirements, trader obligations and remedial actions

review of inspection reports and verifier performance audit reports prepared by the candidate

feedback from supervisors and peers regarding the candidate's ability to verify the performance of instruments in accordance with legislative and organisational procedures

observation of the candidate conducting an inspection.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly. Questioning techniques should suit the language and literacy levels of the candidate.

This competency in practice

Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

An inspector arrives unannounced at a medium size service station to check the performance of a number of fuel dispensers. After introducing him/herself to the site manager, the inspector explains the purpose of the visit and asks for the location of the fuel return points. The inspector performs a safety check, completes an AIP form, places safety barriers around the work area and then prepares the test equipment and reference standards. There are seven fuel dispensers with a total of 38 hoses.

The inspector tests a selection of dispensers visually. The National Test Procedure requires the inspector to dispense fuel into 15L reference measures and then return the fuel to storage. Approximately 90 litres are dispensed per hose. The inspector finds a number of non-compliances on site. Two hoses are dispensing fuel outside the allowable maximum permissible error, one dispenser has a faulty segment in its display and the lights are not working, the diesel dispenser failed the air elimination test and three hoses are badly worn. The inspector removes the verification mark from all non-compliant dispensers.

While testing the fuel dispenser, the inspector notices a number of items displayed for sale outside the office. On closer inspection, some of the pre-packaged items are found not to be marked with a measurement statement.

The inspector meets with the site manager to inform him of the non-compliant dispensers. He/she advises the manager not to use any unmarked dispensers, explains how they can be rectified and issues non- compliance notices. They also discuss the non-compliant pre-packaged articles. The inspector takes details for further action, completes the AIP form and fuel usage report and then departs.
