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 simple measuring instruments 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 instruments 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 simple measuring instruments

identify and implement additional inspection strategies for noninstrument related breaches of national measurement legislation

recognise and act on noncompliance

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

MSATMREFA Use and maintain reference standards

MSATMREF301A Use and maintain reference standards.

Resources may include

simple measuring instruments test equipment and reference standards

computer and relevant software andor 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 candidates 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 has been allocated the task of verifying an area measuring instrument at a tannery In preparation for hisher visit the inspector accesses the organisations database to establish the instrument type site contact details and any previous history for the instrument or trader The inspector assembles the test equipment required for the inspection All reference standards are inspected for damage and validity against their certificate prior to them being stowed with the other equipment safely in the vehicle On arrival at the tannery the inspector introduces himherself to the manager and explains the purpose of the visit and the process involved During this discussion the inspector explains that heshe will inspect the area measuring instrument for compliance with its Certificate of Approval assess the operating environment for factors that may impact on its performance and conduct visual and performance tests in accordance with the National Test Procedure If the instrument complies with these requirements it will be marked as being acceptable for trade use During the subsequent inspection the area instrument is found to have a capacity greater than what is stated in the Certificate of Approval and the instruments performance exceeds the maximum permissible error stated in the national measurement regulations Consequently the inspector removes the previous verification mark from the instrument and issues the trader with a warning that the instrument cannot be used for trade until it has been corrected and verified again Before leaving the premises the inspector provides the trader with some options for rectifying the noncompliances and gives the manager an opportunity to ask any questions about trade measurement activities
