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:

• interpret and apply team requirements, controlling body and category rules and supplementary regulations
• apply safety requirements, including the isolation of equipment and the use of personal protective equipment
• follow task instructions, operating procedures and inspection processes to:

• minimise the risk of injury to self or others
• prevent damage to competition vehicle or equipment
• achieve required outcomes within team time and quality standards

• correctly analyse, repair and conduct post-repair checks on a minimum of four (4) driveline systems faults which could involve:

• selection, noise, vibration, harshness or slipping faults
• faults which give the same effects, but may have multiple causes
• the scope of the faults necessitates the use of a range of testing equipment

• work effectively with others.

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.
