Elements and Performance Criteria

1. Determine master pattern requirements
   • Specifications and drawings are interpreted for required pattern information.
   • Technique/process to achieve suitable quality finish for masters are selected.
   • Materials to produce given item are selected.
   • Tools, equipment and processes appropriate to task are selected.
2. Produce master
   • Materials are marked out and/or construction plan developed to meet specifications/stages of process.
   • Pattern material(s) are prepared.
   • Master is produced.
3. Finish and inspect work
   • Item is checked for compliance with specifications.
   • Weights and measurements are recorded.
   • Sprue material is fitted if necessary.
   • Final finish is applied, where appropriate, and item is stored.
   • Master is evaluated and compared to production sample.

Evidence Required

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 produce jewellery metal masters 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 producing jewellery metal masters 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 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 codes standards manuals and reference materials

Range Statement

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.
Technique/process	High polish
Materials	Jewellery alloys and/or their base metals
