Produce jewellery metal masters

Assessment tool

Version 1.0
Issue Date: May 2024


This unit applies to the manufacture of jewellery master pattern(s) for jewellery reproduction, mainly by the hand held application of processes. Work would be mainly autonomous in a jewellery manufacturing environment.

Understanding the principles of casting/moulding/shrinkage and wax injection is required. General production processes used to finish the reproductions must be understood. Competency in this unit cannot be fully met without appropriate comparison to the finished production item.

Where machining is required as a major component of this manufacturing concept, then unit MEM07005C (Perform general machining) should be selected. The equipment used may include hand and power tools, lathes and non-CNC machines.

Where component(s) require preparation or manufacture by NC/CNC/CAD/CAM as an integral part of this process by the person working autonomously, the relevant competencies should be accessed.

If electro-deposition and/or electro-forming of metal is required, MEM07024B (Operate and monitor machine/process) or Unit MEM08003C (Perform electroplating operations) should also be selected.

This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C5 (AQF level V).

Band: A

Unit Weight: 4

This unit covers the manufacturing jewellery master pattern(s) for jewellery reproduction, mainly by hand held application of processes. It requires the application of precision measurement and hand-making/machine skills to a greater level than that required in Unit MEM19005B (Produce three-dimensional precision items).

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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, 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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
