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

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

Critical aspects for assessment and evidence are:

tyre injury is identified and appropriate action for preparation/inspection determined

consistent application of preparation, inspection and testing standards

safety procedures are always followed.

Context of and specific resources for assessment

Assessment will occur on an HOTR tyre repair facility. 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.

Method of assessment

Competence in this unit may be assessed:

by observation over a range of tyre preparation/inspection procedures undertaken in the workplace

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 appropriate practical/simulation assessment will be combined with targeted questioning to assess the required knowledge, and theoretical assessment will be combined with appropriate practical/simulation or similar assessment.

Guidance information for assessment

Assessment processes and techniques must be appropriate to the language, competency and safety requirements of the site and consistent with workplace systems or procedures.

Required Skills and Knowledge

Required skills

Required skills include:

using skiving, rotary cutting and buffing tools

taking measurements

using required inspection equipment

communicating effectively

working safely in accordance with operational requirements and safe systems of work

reading and interpreting typical product specifications, job sheets and material labels as provided to operators

writing to the level of completing workplace forms and production reports

Required knowledge

Required knowledge includes:

organisational procedures

heavy off-the-road (HOTR) tyre construction

methods of identifying injury position, lug/position identification

tyre injury repair preparation methods

hazards and hazard controls associated with HOTR tyre repair preparation

reporting 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.

Tyre securing methods

Required tools

Required tools may include, but are not limited to:

Foreign material

Foreign material that may contaminate the injury area or cause a health risk must be removed (e.g. spray paint used to mark tyres). This will include removing any rocks or other foreign material

Injuries to tyres

Injuries to tyres may include, but are not limited to:

cuts, abrasion, splits, cracks and crazing

separations within the structure

deformities both surface and internal

penetrations into and through the casing/carcass

Location of repairs

Repairs may be undertaken to the:

tread or crown, including steel components

Injuries

Injuries may include, but are not limited to:

injuries which do not need repair and should be returned to the customer to be used as is

Hidden injuries

Hidden injuries may include, but are not limited to:

cuts

oxidation

separations

Standards

Standards may include, but are not limited to:

AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair – Tyres

Procedures

Procedures may be written, verbal, computer-based or in some other form. They may include, but are not limited to:

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

Procedures would be expected to comply with any relevant government regulations.

Paperwork

Paperwork may be paper or electronic-based

Appropriate action

Appropriate action includes, but is not limited to:

determining problems needing action

accessing and applying relevant technical and plant data

applying appropriate problem solving techniques to determine 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/ability to designated person

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state 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.
