EVIDENCE GUIDE

Resource implications

•

Access to a realistic requirement and objective(s) for
analysis and evaluation, light marine 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
