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 three-dimensional jewellery items. 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 jewellery manufacture 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

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

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.

Required skills

Look for evidence that confirms skills in:

interpreting design specifications and following instructions (oral or written)

interpreting drawings

weighing and measuring

selecting appropriate tools and equipment

selecting appropriate materials and manufacturing techniques

applying appropriate fabrication and finishing procedures, which may include electroplating

identifying alternative metals/materials

meeting compliance specifications

reading and interpreting routine information on written job instructions, specifications and standard operating procedures. May include drawings

entering routine and familiar information onto proformas and standard workplace forms

Required knowledge

Look for evidence that confirms knowledge of:

reasons for selecting particular metals, construction methods, manufacturing and finishing techniques

tools and equipment matched to processes

planning/process stages

working properties of precious and non-precious metals

fine detail manufacturing processes

knowledge of workplace hazards and emergency procedures

various components of jewellery items

appropriate measuring devices and recording methods

procedures for final treatment/safe handling and storage of items

occupational health and safety procedures

use and application of personal protective equipment

safe work practices and procedures

relevant hazards and control measures related to the competency

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.

Items

Items involving a range of fabrication processes and techniques, for example various rings, broaches, bracelets, neckpieces

Material/s

Precious and non-precious metals

Consumables including solders and fluxes, drills and blades, polishing compounds, cleaning and finishing materials, adhesives

Tools, equipment

All hand and power tools appropriate to construction and repair of jewellery items and personal protective equipment

Appropriate preparation and fabrication techniques

Cutting, folding, bending, curving, dapping, drawing, rolling, doming, annealing, melting, granulation

Primarily by brazing/silver soldering but may include other methods such as riveting

Documentation

Job packet, work instructions and procedures, parts and components reference material, materials and consumables used, time and record sheets, drawings/illustrations, customer verbal/written specifications

Final finish

Filing, emery finishing, high and satin polish, various embellishment finishes (sandblasting, brushed, burring, reticulation, burnishing etc.)

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.
