Resource implications

•

Access to a realistic requirement and objective(s) for
analysis and evaluation, wheeled mobile plant transmission
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
