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

A person who demonstrates competency in this unit must be able to verify reference standards. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with verifying reference standards, or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Required skills

Look for evidence that confirms skills in:

researching and identifying suitable reference standards for verification within standards hierarchy

accessing reference manuals to gain appropriate information concerning tolerances for reference standards

completing the organisation's information tracking documentation

identifying operational errors relevant to the verification

locating identification marks on reference standards

researching design features on a range of reference standards

completing verification work sheets

completing and issuing certificates of verification

Required knowledge

Look for evidence that confirms knowledge of:

relevant categories of reference standards for which the organisation is authorised to verify

a range of classes for reference standards

appropriate tolerance for a range of reference standards

current status of clients' reference standards

atmospheric factors required for verifying a range of reference standards

remedial action for atmospheric deficiencies

environmental factors that may adversely influence the integrity of the reference standards

remedial action for a range of environmental deficiencies

requirements for identification marking on reference standards

the purpose of design specifications

the purpose of the major components and functions of reference standards

the fundamental features of reference standards

the process for maintaining integrity of results including calculation

the reference material for uncertainty and maximum permissible errors for a variety of reference standards.

the process for producing certificates of verification in accordance with verifying authority status

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Reference standards

Mass, volume, density, area, length, master meters, temperature

Operating procedures

Manufacturers' specifications, industry guidelines, Australian standards, legislation, organisational procedures and guidelines

Legislation and policies

Enabling legislation, organisational procedures and guidelines

Workplace health and safety legislation including storage and transportation of test equipment, handling of test equipment, handling of hazardous materials, safety clothing, manual handling techniques, site/premises conditions

Documentation
