Evidence Required

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

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

all reasonably available repair techniques and materials were considered

appropriate techniques and materials have been selected

the reasons for choosing the technique and materials are sound

the product meets its required performance

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 diagnosing items requiring repair selecting suitable methods justifying methods chosen and then repairing items using those methods

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

Method of assessment

A single assessment event is not appropriate Onthejob assessment should be included as part of the assessment process wherever possible Where assessment occurs off the job judgement must consider evidence of the candidates 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 supervisors 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

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

Appropriate repair process

Appropriate repair process refers to that combination of materials and fabrication techniques which has:

compliance with product requirements

greatest ease of execution

best financial return

greatest sustainability contribution

Sustainability

Sustainability incorporates the three aspects of:

survival of the ecology/physical environment – which means that an enterprise needs to manage the impact of the business to ensure the survival of the physical environment

economic viability – efficiency, cost and waste reduction and competitiveness to support survival of the business

social sustainability – an enterprise needs to manage the impact of the business to ensure its continued survival within the community and the survival of the community, including occupational health and safety (OHS)

Incidental design

Incidental design includes minor design which is incidental to conducting a repair and which:

improves on an original design weakness (e.g. such as might be shown up by the failure being repaired)

changes the original design to incorporate current techniques, materials or practices

better meets customer needs

Preparing materials

Preparing materials includes:

cutting to size and shape, as required

any pre-treatment required

calculating amount of resin and resin components required

mixing resin systems

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:

cost/benefit of different repair techniques and materials

customer wants more improvement than is technically feasible

customer wants more improvements than insurance will pay for

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
