EVIDENCE GUIDE 

Resource implications 

•  Access to a realistic requirement and objective(s) for 

analysis and evaluation, operational climate control 
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
