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 one class of weighing 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

install and repair weighing instruments to meet statutory requirements

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)

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:

limited weighing instruments, test equipment and reference standards

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 and remedial actions

review of verification reports prepared by the candidate

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

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.

A retail butcher uses a digital weighing instrument to sell meat with a gross retail cost of $500,000 annually and where the price per kilogram ranges from 5.99/kg to $68/kg. As the profit margin of the butcher's business depends on the product received and sold, the butcher contracts a scale repair company to test his buying and selling scales for accuracy.The scale repairer arrives at the butcher's premises with a trolley load of equipment. After their introductions, the butcher enquires as to what all the gear on the trolley is for. The repairer explains that it is all part of the equipment needed to satisfy the licensing requirements of national Trade Measurement.

The repairer advises that for this job he needs masses which have a suitable capacity and accuracy for the scale, that have been tested and are still within their expiry period. Not only does he need 15kg for the capacity of the instrument but also smaller masses down to 0.2g to test the scale correctly according to the National Test Procedures that he has brought with him. To keep up to date with new scales, he also has a laptop with internet access to download the latest Certificate of Approval for the instrument from the National Measurement Institute website. Regardless of how accurate the scale is, it can't be used for trade (i.e. buying or selling) unless it is approved for trade use by the National Measurement Institute. He also has the paper work required by national Trade Measurement to issue depending on whether the instrument complies and can be certified or not. Finally, he explains that he has tools in case the scales need adjustment if they are outside the maximum permissible errors set down by the National Measurement Institute.

The scale repairer inspects the scales for compliance with the Certificates of Approval and tests them. He finds the selling scale is approved for trade use but is incorrect and the buying scale, while weighing correctly, is not approved.The repairer fixes the selling scale, marks it with a certification mark and issues a certification form. The buyingscale cannot be certified because it is not an approved type and the repairer issues a notice of non-compliance advising the butcher that it can no longer be used for trade. Before leaving the butcher shop, the repairer completes his paper work and submits it to national Trade Measurement within the specified 14 days.
