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.

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:

apply the required skills and knowledge to the hand lay up process

apply approved procedures.

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

composites production standards are met consistently

all safety procedures are always followed.

Assessment method and context

Assessment will occur during the hand lay up process for composites and will be undertaken in a work-like environment.

Competence in this unit may be assessed:

through use of industrial hand lay up composite manufacture, using jobs of appropriate complexity

in a situation allowing for operation under all normal and a range of abnormal conditions

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 an operational knowledge of the materials, equipment and process sufficient to recognise out of specification products, process problems and materials faults. For example, excess resin will only add weight and weaken the finished product. Therefore care needs to be taken to ensure the correct resin to fibre ratio is used.

Knowledge of organization procedures, 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 hand lay up process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.

Knowledge of and skills in the operation of hand lay up equipment and the main components sufficient for consistent production of quality products including:

production workflow sequences and materials demand

accurately monitoring equipment and product quality

understanding the potential effects of variations in raw materials and equipment in relation to quality of product

waste management and understanding the importance of reusing non-conforming products wherever possible

correct selection and use of equipment, materials, processes and procedures

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

setting up moulds

preparation of resins, including mixing as required

preparation of fibre reinforcement, including cutting and trimming

use of composites materials, including gel coats, resins and fibres

methods of application of composite materials to the mould by hand lay up.

Competence also includes the ability to:

plan own work, including predicting consequences and identifying improvements

identify when the operator is able to rectify faults, when assistance is required and who is the appropriate source for assistance

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

Language, literacy and numeracy requirements

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

Writing is required to the level of completing workplace forms.

Numeracy is required to the level of reading tables of figures and graphs (and applying the resultant information), using formula percentages/ratios to determine the required mass of an additive (catalyst, pigment etc.) and similar manipulations and interpretation.

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 unit includes the use of equipment and materials to form composite products using hand lay up processes. It includes the operation of all relevant additional equipment where that equipment is integral to the hand lay up process.

Procedures

All operations are performed in accordance with procedures.

Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.

Tools and equipment

This competency includes use of equipment and tools such as:

open moulds for composite products

hand mixing equipment and stirrers

knives and cutters to trim fibres

hand application tools, rollers, brushes, etc

relevant personal protective equipment.

Hazards

Typical hazards include:

hazardous materials and vapours

manual handling hazards

fire hazards due to flammable nature of resins used

knife hazards

glass (and other) fibre hazards (inhalation and skin penetration)

slip hazards (spilled resin).

Problems

Respond to/rectify 'non-routine problems' means 'apply known solutions to a limited range of predictable problems'. Typical process problems may include:

cracks, dents or imperfections of the mould

incorrect resin ratios

contamination of materials

shifting of fibres before resin laid

stacking of fibre and resin sequence problems.

Typical product problems may include:

voids

poor surface finish

colour contamination

release from mould damage.

Appropriate action for non-routine problems may be reporting to designated person or other action specified in the procedures.

Variables

Key variables to be monitored include:

ambient temperature

air flow/ventilation rate

viscosity of resin

time since resin mixed vs pot life of mix
