Before you can start an apprenticeship, you first need to find an employer in the industry you're interested in that will support you through your studies. You and your employer should contact an Apprenticeship Network Provider (ANP) and tell them you're interested in studying at TAFE NSW.

The ANP will help you and your employer to complete a Training Contract. Once you have a Training Contract, we will help you, your employer and the ANP to complete a Training Plan Proposal. Once you have both these documents, the ANP will lodge them with State Training Services, who will provide further advice about next steps.
