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 methods and techniques which are appropriate to the circumstances
• complete preparatory activity in a systematic manner
• test marine electrical systems and components
• complete diagnosis of faults correctly
• diagnose and repair a range of marine electrical systems and components to manufacturer and component supplier requirements, including dash instrumentation, switch and fuse panels, bilge pumps and lighting within workplace timeframes
• test prior to placing in service
• complete workplace and equipment records and workplace clean up requirements.

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:

• workplace location or simulated workplace
• faulty marine electrical systems and components
• equipment, hand and power tooling appropriate to the diagnosis and repair of faults in marine electrical system components
• 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 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.
