3
Context of assessment
a
Assessment of competency must comply with the assessment requirements of the relevant maritime regulations
b
Assessment of this unit must be undertaken within relevant marine authority approved and audited arrangements by a registered training organisation:

1
As a minimum, assessment of knowledge must be conducted through appropriate written/oral examinations
