EVIDENCE GUIDE 

Resource implications 

• 

Access to a realistic requirement and objective(s) for 
analysis and evaluation, light vehicle braking systems with 
real or simulated faults, monitoring processes and testing 
equipment appropriate to the objective(s), research facilities 
and technical information and a realistic work environment 

Method of assessment 

• 

Assessment of this competency is most likely to be project 
related under real or simulated conditions and require 
portfolios or other forms of indirect evidence of process. 
Direct evidence may include certification of compliance of 
the final outcome/product or authorisation for use by a 
competent authority 

• 

Assessment must confirm the inference that competency is 
able not only to be satisfied under the particular 
circumstances, but is able to be transferred to other 
circumstances 

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
