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, the range statement and the assessment guidelines for this training package.

Overview of assessment

A holistic approach should be taken to the assessment.

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.

Where the assessee does not currently possess evidence of competency in PMBPROD292B Operate pultrusion equipment, it may be co-assessed with this unit.

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

It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:

identify critical materials properties and pultrusion composites process characteristics in relation to the process requirements and the end product

make adjustments to the process as required

identify and take appropriate action on problems and potential problems.

Consistent performance should be demonstrated. For example, look to see that:

the process runs consistently and smoothly with the minimum need for human intervention

all safety procedures are always followed.

Assessment method and context

Assessment will occur on an industrial pultrusion machine(s) equipment and will be undertaken in a work-like environment.

Competence in this unit may be assessed:

using an appropriate, operating plant requiring demonstration of start-up, operation and shutdown procedures

in a situation allowing for the generation of evidence of the ability to recognise, anticipate and respond to problems

by using a suitable simulation and/or a range of case studies/scenarios

through a combination of these techniques.

In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.

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

Specific resources for assessment

This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

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.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level required for this unit.

Application of knowledge of the materials, equipment and process sufficient to recognise material and equipment conditions which may lead to out of specification production.

Knowledge of organization procedures, quality requirements at each production stage and relevant regulatory requirements and the ability to implement them within appropriate time constraints and work standards.

Application of the knowledge of managing risks using the hierarchy of controls applied to the pultrusion process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.

Knowledge as a basis for solving processing and material problems including:

characteristics of materials and behaviour in relation to heat, pressure, flow rate and time

properties of the materials required to form a composite structure of the required strength and surface finish

function and operating principles of equipment, machine components and ancillary equipment

adjustments to bring process on line

impact of machine speed, temperature, pressure, on product quality and production output

nature of mechanical, hydraulic, pneumatic, electrical and electronic principles which effect machine operation and product development

impact of variations in raw materials and equipment operation in relation to final product

changes to materials at various stages of production

waste management and importance of non-conforming materials

polymer properties and their interactions with process conditions

relationships between polymer properties and process conditions

changes to polymer properties to better suit process requirements

product problems related to polymer properties

product problems related to process conditions

adjustments to process conditions to meet polymer and product requirements.

Competence also includes the ability to:

plan own work, including predicting consequences and identifying improvements

maintain output and product quality using appropriate instruments, controls, test information and readings

identify and describe own role and role of others involved directly in the process

identify factors which may affect product quality or production output and appropriate remedies

identify when assistance is required to solve problems

set up dies, pullers or formers

use composites materials including release agents, resins and fibre reinforcement

use of surface finishing equipment

operation of equipment including PLC controls

curing of products including application of wraps, heat or pressure.

Language, literacy and numeracy requirements

This unit requires the ability to read and interpret typical product specifications, job sheets and material labels as provided to operators.

Writing is required to the level of completing workplace forms, quality assurance records and production reports.

Numeracy is required to the level of determining required weights/volumes of materials in a resin mix for different circumstances (using a data sheet), number of layers of impregnated matrix required to yield the required product laminate thickness, and similar activities.

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. Add any 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.

Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.

Context

This competency applies to the production of composite products by pultrusion processes. It includes the operation of all relevant additional equipment where that equipment is integral to the composites forming process.

Procedures
