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 perform production machining including responsibility for selecting and mounting tooling and setting of machine within defined parameters

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

Assessors must be satisfied that the candidate can competently and consistently apply the skills covered in this unit of competency in new and different situations and contexts Critical aspects of assessment and evidence include

correct job planning including identifying job requirements from drawings instructions or specifications and sequence of operations

selecting appropriate tooling measuring equipment material and accessories from a predetermined range

selecting and mounting required tooling or grinding wheels

setting machining parameters

checking machined components for conformance to specifications

Context of and specific resources for assessment

Assessment should emphasise a workplace context and procedures found in the candidates workplace

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

Method of assessment

Assessment should occur on a variety of machines and across a range of machining tasks Assessment must include consideration of performance evidence as demonstrated in a volume production environment The candidate must be able to demonstrate performance across a sufficient range of appropriate tasks and materials to cover the scope of application for this unit

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 supervisors 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 manuals and reference materials

Guidance information for assessment

This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with performing general machining or other units requiring the exercise of the skills and knowledge covered by 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
