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 

Assessors must be satisfied that the candidate can competently and consistently:

• observe safety procedures and requirements
• communicate effectively with others involved in or affected by the work
• select repair methods and techniques appropriate to the circumstances
• complete preparatory activity in a systematic manner
• repair and rebuild a range of two and four cycle outboard engines from single cylinder to current multi-cylinder engines and their components to manufacturer and component specifications
• complete the repair of two and four cycle outboard engine and components within workplace timeframes
• complete workplace records.

Context of , and specific resources for assessment 

• The application of competency is to be assessed in the workplace or a simulated environment that reflects as far as possible the actual working environment.
• Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints.
• Assessment is to comply with relevant regulatory requirements, including specified Australian standards.
• Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
• The following resources should be made available:

• appropriate worksite
• range of two and four cycle marine engines and components
• specifications and work instructions
• equipment, hand and power tooling appropriate to repairing marine engines
• relevant information, including manufacturer specifications.

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 may be applied under project-related conditions (real or simulated) and require evidence of process.
• Assessment must confirm a reasonable inference 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 functional units which together form part of the holistic work role.

Guidance information for assessment 

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