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

A person who demonstrates competency in this unit must be able to maintain and rectify induction/exhaust systems. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with maintaining and rectifying induction/exhaust systems, or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

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, supervisor's 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

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

planning and sequencing operations

checking task-related information

checking for conformance to specification

identifying a variety of applications of supercharging, filtering inter and after cooling

checking the induction/exhaust system for correct operation in accordance with standard operating procedures

determining the flows, pressures and temperatures of the given induction/exhaust system using appropriate techniques and equipment

isolating faulty component in accordance with standard operating procedures

using all test instruments and equipment

visually and dimensionally checking component parts for wear

using supplier catalogues to select component parts

removing components and fitting to engines

recording all test and, where appropriate, repair activities

checking the induction/exhaust system for leaks

undertaking calculations and numerical operations within the scope of this unit

Required knowledge

Look for evidence that confirms knowledge of:

the principles and terminology of supercharging, filtering, inter and after cooling

the performance and operational specifications of the induction/exhaust system

the procedures and safety precautions for testing induction/exhaust systems for correct operation

the equipment and procedures necessary to test flows, pressures and temperatures associated with induction/exhaust systems

the procedures for recording flows, pressures and temperatures

common faults associated with induction/exhaust systems and causes of those faults

the appropriate action and procedures for correcting common faults in induction/exhaust systems

the component specifications/tolerances and actions to be taken if the components are outside of specification

the action to be taken if the components are 'just' within specification

the measuring instruments to be used to carry out dimensional checks on components

the procedures and safety precautions for removing/fitting components to engines

the procedures for recording test and repair activities undertaken on induction/exhaust systems

the consequences of air/exhaust leaks on the safe operation of the induction/exhaust system and procedures for testing for leaks in induction/exhaust systems

safe work practices and 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. 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.

Supercharging

Supercharging apparatus includes turbo charging equipment
