Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

Overview of assessment

A person who demonstrates competency in this unit must be able to use a CAD program to produce 3D drawings and perspectives of jewellery or object designs.

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

Assessors must be satisfied that the candidate can competently and consistently:

demonstrate accurate CAD techniques to create and display features of jewellery or object designs

produce 3D CAD models of jewellery or object designs from single, two and three point perspectives

communicate effectively and work safely with others in the work area.

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 applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Required Skills and Knowledge

Required knowledge includes:

state or territory OHS legislation, regulations, standards and codes of practice relevant to the full range of processes for using CAD applications

elements and principles of design

terminology and symbols used in drawings and CAD software

types of CAD equipment and procedures for their safe use, operation and maintenance

computer programs and CAD applications

drafting and drawing codes and practices relevant to jewellery and object design

2D and 3D drawing techniques

appropriate mathematical procedures for estimation and measurement

documentation control procedures

problem identification and resolution techniques

jewellery and object design and construction techniques
