Employability Skills

Employability Skills are part of a unit of competency.

Employability Skills statements from a selection of units of competency from the DEF42512 Certificate IV in Work Health Safety have been reproduced in the table below.

This table provides an example of Employability Skills for the qualification because Employability Skills within a qualification will vary depending on the qualification packaging options.

Public Safety qualifications have core units (which must be achieved) and elective units (where there is a choice of units which must be achieved) so different Employability Skills Summaries are possible within the one qualification, depending on the package of core units and chosen elective units.
