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

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge

A person who demonstrates competency in this unit must be able to

observe safety procedures and requirements

select boring and honing methods and techniques appropriate to the circumstances

complete preparatory activity in a systematic manner

fit a range of sleeves to engines according to workplace manufacturer and component supplier requirements

bore and hone a range of multicylinder engines according to workplace manufacturer and component supplier requirements

complete work without damage to tools and equipment or injury to persons

Context of and specific resources for assessment

Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting Performance is demonstrated consistently over a period of time and in a suitable range of contexts

Assessment is to occur

using standard workplace practices and procedures

following safety requirements

applying environmental constraints

Assessment is to comply with relevant

regulatory requirements

Australian standards

industry codes of practice

The following resources must be made available for the assessment of this unit

appropriate worksite

multicylinder engine blocks appropriate to the workplace including inline multicylinder engine blocks and veeconfiguration multicylinder engine blocks

fixed and portable hand air and power tools and equipment appropriate to reboring and honing cylinders and barrels

specifications and work instructions

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of this Training Package

Assessment methods must confirm consistency and accuracy of performance over time and in a range of workplace relevant contexts together with application of required skills and knowledge

Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure its correct interpretation and application

Assessment must confirm that competency is able not only to be satisfied under the particular circumstance but is able to be transferred to other circumstances

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

Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability

Assessment processes and techniques must be culturally sensitive and appropriate to the language and literacy capacity of the candidate and the work being performed
