You may complete your apprenticeship or traineeship when all of the required units of competency have been achieved.
For example, apprentice carpenter Luke has completed all of the 30 units of competency within the Certificate III Carpentry, which means he can complete his apprenticeship.
If this occurs prior to the term of the Training Contract, it is known as early completion.
Generally, in order for early completion to be finalised, your employer support is required.
