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

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 fair and shape surfaces. 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, mat-erials handling, recording and reporting associated with fairing and shaping surfaces, 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

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

determining and applying job requirements

identifying and selecting materials to be prepared

filling/sanding/grinding, fairing and shaping to requirements

setting up and using safety equipment such as fans, extraction unit

preparing fillers and abrasive materials

setting up and using sanding/grinding, power tools such as disc sander, angle grinder and associated safety accessories such as dust extraction assemblies and guard protection

surface filling, sanding, internal and external sanding to achieve flat, concave and convex surfaces

using personal safety protection

checking surface and finish visually and by use of fairing battens, straightedges, stringlines, french curves, templates etc.

Required knowledge

Look for evidence that confirms knowledge of:

filling and fairing specifications

types, properties and characteristics of fillers and materials to be prepared and features/specific preparation requirements

filler ingredient measuring and preparation techniques

relevant safety equipment and uses/application

filling, fairing and shaping techniques

equipment and accessories and applications

means of optimising life of abrasive materials and reducing waste

personal safety procedures and protective equipment relevant to sanding/grinding practices

safety hazards and hazard reduction relating to faired materials, fillers and abrasives

compliance testing procedures

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.
