If you don’t pass all of the subjects in your superseded qualification during the teach-out period (until 2 April 2023), you will not be eligible to receive the full qualification graduation documents. In this case, you would need to upgrade to the new training package and may be required to complete some new subjects to be eligible for that new qualification.
You should be eligible for Credit Transfer for any equivalent units you have already completed. There may also be upgrade courses available that will identify and address gaps between the old and new qualifications.
