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.

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

Assessment for this unit of competency will occur on the job.

It is essential that the process and equipment be understood and that the importance of critical material properties, settings and readings is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

waste is minimised

product is made efficiently and to standard

tools and equipment are appropriately maintained.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

Context of and specific resources for assessment

Assessment will require the fabrication of suitable objects using open moulding techniques.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Method of assessment

Typically, persons engaged in composites trade work are required to apply their skills and techniques across a range of jobs and specifications.

A single assessment event is not appropriate. On the job assessment must be included as part of the assessment process. Assessment judgements must consider evidence of the candidate's performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit.

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

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 skills

Required skills include:

interpreting specifications and instructions

calculation of material quantities

working safely and using personal protective equipment

removing included air

using rollers, brushes and/or chopper gun

performing vacuum leak testing

doing minor maintenance to chopper guns and/or pump systems (reciprocating airless pumps with air support)

operating and maintaining solvent cleaner (filter)

undertaking mechanically assisted movement of large parts (e.g. chain hoist)

assembling, cleaning and preparing simple and complex moulds

releasing product from simple and complex moulds (using jacks, air and water)

applying release systems (wax)

ensuring compliance to specifications

Required knowledge

Required knowledge includes:

preparation schedules, terminology and information relevant to standard work instructions

applicable codes and regulations

safe work practices and correct use of personal protective equipment

release agents surface tension

managing lay-up teams

gel coat application

reinforcement lay-up

resin types and applications

common tools/equipment and their maintenance

correct laminating techniques and finishing off (e.g. detail consolidation/rolling, check consistency and evenness of resin/glass, remove air entrapment and check with light)

managing post-cure requirements (e.g. air cure and oven cure)

production environment variables, such as effect of humidity (e.g. epoxy backbone), temperature, ultraviolet (UV) light and contamination from other processes

managing hazardous environments (e.g. styrene levels)

function of catalysts, accelerators and promoters

control of overspray

storage of moulds

housekeeping

waste disposal

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.

Procedures

Procedures may be written, verbal, computer-based or in some other form, and may include:

all work instructions

standard operating procedures

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant

good operating practice as may be defined by industry codes of practice (e.g. Responsible Care) and government regulations

Open moulding techniques

Open moulding techniques may include:

hand lay-up

chopper gun

filament winding

Requirements of product

Requirements of product may be determined from various sources, including:

drawings

product specifications

customer requests

descriptions of required use of product

Equipment

Equipment includes:

moulds and mould components

resin application and dispersion tools

Preparing reinforcing

Preparing reinforcing includes:

cutting to size/shape, as required

any pre-treatment required

Logs and reports

Logs and reports may include:

paper or electronic based

verbal reports

items found which require action

Appropriate action

Appropriate action includes:

determining problems needing action

determining possible fault causes

rectifying problem using appropriate solution within area of responsibility

following through items initiated until final resolution has occurred

reporting problems outside area of responsibility to designated person

Typical problems

Typical problems may include:

contamination

air entrapment

resin rich

uneven distribution of resin

difficult mould shapes

resin curing too quickly

resin curing too slowly

failure to release

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence
