EVIDENCE GUIDE 

Resource implications 

•  Access to operational electronic systems requiring 

modification, testing equipment as stipulated in the 
Range Statement, technical information and a realistic 
work environment 

Method of assessment 

•  Assessment of this competency is most likely to be 

project related and require portfolios or other forms of 
indirect evidence of process. Direct evidence will 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 
projects 

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
