• 

Access to a realistic requirement and objective(s) for 
analysis and evaluation, operational gas fuel 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
