analysis and evaluation, mobile plant engine and 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
