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 is fully observed and there is ability to transfer competence to changing circumstances and to respond to unusual situations 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

conducting the work in accordance with workplace requirements

interpreting measurements and specifications

carrying out reconditioning to manufacturer/component supplier requirements

measuring and checking against manufacturer/ component supplier specifications

completing a range of cylinder head reconditioning, assembly and testing procedures to manufacturer/ component supplier specifications

cylinder head is presented to customer in compliance with workplace requirements

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

material relevant to reconditioning cylinder heads

equipment, hand and power tooling appropriate to reconditioning cylinder heads

activities covering 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 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 that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other 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

apply research and interpretive skills sufficient to locate, interpret and apply manufacturer/component supplier procedures, workplace policies and procedures

apply analytical skills required for identification and analysis of technical information

apply plain English literacy and communication skills in relation to dealing with customers and team members

apply questioning and active listening skills for example when obtaining information from customers

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

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

establish safe and effective work processes which anticipate and/or resolve problems and downtime, to systematically develop solutions to avoid or minimise reworking and avoid wastage

use workplace technology related to reconditioning cylinder heads, including the use of measuring equipment and communication devices, diagnostic and specialist tooling and equipment, computerised technology, and the reporting/ documenting of results

Required knowledge

A working knowledge of:

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

personal safety requirements

assembly/reconditioning procedures

technical information

equipment safety requirements

enterprise quality procedures

work organisation and planning processes

manual handling techniques
