EVIDENCE GUIDE 

Resource implications 

•  Access to competition vehicles and associated assembly tools 

in real or appropriately simulated situations involving the 
application of selection and preparation techniques and the 
related computing, operational and inventory support systems 

This includes real or simulated concepts, work areas, material, 
equipment and information on work specifications, customer 
requirements, organisation procedures, relevant safety 
procedures and regulations and quality standards 

Method of assessment 

•  Assessment methods must confirm consistency of 

performance over time and in a range of workplace relevant 
contexts 

•  Assessment should be by direct observation of tasks and 

questioning on underpinning knowledge 

•  Assessment should be conducted over time and may be in 

conjunction with assessment of other units of competency 

Context/s of assessment 

•  Assessment may occur on the job or in a workplace simulated 

facility with relevant process equipment, material, work 
instructions and deadlines
