8 Where simulators are used to assess the ability
of candidates to demonstrate levels of competency, assessors shall
ensure that:
-
.1 performance criteria are identified clearly
and explicitly and are valid and available to the candidates;
-
.2 assessment criteria are established clearly
and are explicit to ensure reliability and uniformity of assessment
and to optimize objective measurement and evaluation, so that subjective
judgements are kept to the minimum;
-
.3 candidates are briefed clearly on the tasks
and/or skills to be assessed and on the tasks and performance criteria
by which their competency will be determined;
-
.4 assessment of performance takes into account
normal operating procedures and any behavioural interaction with other
candidates on the simulator or with simulator staff;
-
.5 scoring or grading methods to assess performance
are used with caution until they have been validated; and
-
.6 the prime criterion is that a candidate demonstrates
the ability to carry out a task safely and effectively to the satisfaction
of the assessor.
