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
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 reconditioning methods and techniques appropriate to the circumstances
complete preparatory activity in a systematic manner
conduct reconditioning of a range of cylinder heads according to workplace, manufacturer and component supplier requirements
complete reconditioning of cylinder heads within workplace timeframes
complete work without damage to tools and equipment or injury to persons.
Context of, and specific resources for assessment
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
cylinder heads appropriate to the workplace, including multi-valve, OHV and OHC cylinder heads
fixed and portable hand, air and power tools and equipment appropriate to reconditioning cylinder heads
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.
