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 prepare tyre casings for retreading

apply approved procedures.

Consistent performance should be demonstrated. For example, look to see thatproduction standards are met consistently.

Assessment method and context

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

Competence in this unit may be assessed:

by using an appropriate, industrial tyre buffing machine requiring demonstration of operation and start/stop procedures

in a situation allowing for the generation of evidence of the ability to 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 out of specification products, process problems and materials faults.

A knowledge of organization procedures, relevant regulatory requirements and the ability to implement them within appropriate time constraints and work standards. For example the minimum allowable depth of cover over the belt before retreading.

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

Show knowledge of and skills in the preparation of tyre casings for retreading and its main components sufficient for the consistent production of quality products including:

different mould part types

types of releasing agents

role of releasing agents

procedures

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

Competence includes knowledge of:

production workflow sequences and materials demand

the reasons for checking process controls

the normal range of process variability

the potential effects of variations in materials and equipment operation in relation to quality of product.

purpose of the buffing and repair processes

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

Competence also includes the ability to:

check process controls and report readings which are outside the normal range of process variability

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

recognise pre-cure retreads and cured recaps, remould retreads and the relevant procedures to buff casings for each type

explain the effect of unauthorised or emergency shutdown in relation to safety and production requirements

plan own work, including predicting consequences and identifying improvements

accurately monitor equipment operation and product quality

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 preparation of tyre casing for retreading process.

Language, literacy and numeracy requirements

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

Writing is required to the level of completing workplace forms.

Basic numeracy is required, eg to determine that two 25 kg bags are needed to make up a requirement for 50 kg.

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 manual handling aids and various powered equipment/aids. This competency applies to work environments and sectors within the rubber industry. It includes the operation of all relevant ancillary equipment.

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. These may include:

movement of materials

stacking of materials

basic measurement of quantities

basic pre-blending of materials.

Tools and equipment

This competency includes use of equipment and tools such as:

hand carts and trolleys

knives and other bag opening equipment

hoists/lifting equipment not requiring any special permits or licences

bung spanners and similar

basic hand tools required for opening of material packaging

relevant personal protective equipment.

Hazards

Typical hazards include:

spills

dusts/vapours

hazardous materials (including rubber dust produced during the buffing process)

manual handling hazards

knife hazards.

Problems

Respond to routine problems' means 'apply known solutions to a variety of predictable problems'. Typical process and product problems may include:

variations in tyres

contamination of tyres

damaged tyres.

wrong raw materials

inappropriate blade selection

insufficient or too deep buffing.
