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!

  2. Function and operation of the system when operating correctly are identified.
  3. Systematic fault-finding processes are used across relevant systems to determine the extent of the fault.
  4. Additional technical sources are consulted to assist with analysis, if necessary.

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

It is essential that competence in this unit signifies ability to transfer competence to changing circumstances and to respond to unusual circumstances in the critical aspects of:

observing safety procedures and requirements

communicating effectively with others involved in or affected by the work

selecting methods and techniques appropriate to the circumstances

completing preparatory activity in a systematic manner

analysing faults in complex systems, identifying the cause(s) of faults and establishing repair requirements within an established timeframe for faults incorporating at least three of the following single systems: mechanical, hydraulic, pneumatic and electrical/electronic.

Context of, and specific resources for assessment

Application of competence is to be assessed in the workplace or simulated worksite.

Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints.

Assessment is to comply with regulatory requirements, including Australian Standards.

The following resources should be made available:

workplace location or simulated workplace

materials relevant to the diagnosis of complex system faults

equipment, hand and power tooling appropriate to the diagnosis of complex system faults

activities covering the mandatory task requirements

specifications and work instructions.

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the automotive industry's RS&R Training Package.

Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.

Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies.

Assessment may be applied under project related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competence is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

It is preferable assessment reflects a process rather than an event and occurs over a period of time to cover the varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other appropriate persons subject to agreed authentication arrangements.

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role

Guidance information for assessment

Required Skills and Knowledge

Required skills

apply oral communication skills sufficient to convey information and concepts to customers

apply planning and organising skills to own work activities, including making good use of time and resources, sorting out priorities and monitoring own performance

interact effectively with other persons both on a one-to-one basis and in groups, including understanding and responding to the needs of a customer and working effectively as a member of a team to achieve a shared goal

the capacity to apply problem-solving strategies in purposeful ways, both in situations where the problem and desired solution are clearly evident and in situations requiring critical thinking and a creative approach to achieve an outcome

use mathematical ideas and techniques to calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks

use workplace technology related to the diagnosis of complex system faults, including the use of measuring equipment, computerised technology and electronics, communication devices and reporting/documenting of results

Required knowledge

A working knowledge of:

OH&S regulations/requirements, equipment, material and personal safety requirements

function and operation of the appropriate complex automotive systems

symptom and cause differentiation

diagnostic procedures and problem-solving techniques

test procedures and test instrument application

documenting and reporting procedures

enterprise quality procedures

work organisation and planning processes

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.

Complex systems

A complex system is defined as one which integrates two or more automotive systems, or incorporates three or more of mechanical, hydraulic, pneumatic, electrical or electronic media. Examples include hydraulically/ electronically controlled automatic transmissions, anti-lock braking systems, engine management systems integrating ignition, fuel and transmission control systems.

Workplace example:

Customer reports intermittent shifting into top gear on an electronically controlled automatic transmission. The customer is asked a number of questions about the conditions in which the problem occurs (e.g. frequency of the problem, speed, road conditions). A road test is conducted, and the technician detects intermittent speedometer operation. After testing of electrical connections, components and sensors, the intermittent speedometer operation is confirmed to be the problem. Repair requirements are determined to be securing the connections on the speedometer wiring.

Diagnostic methods

Diagnostic methods are to include:

questioning of customer

road testing

hydraulic testing (e.g. performance testing of power steering systems)

electrical testing (e.g. performance testing of engine starting systems)
