A Certificate III is a job-ready qualification built from a set of units. Where the rules state a total, the middle value is 16 units, and the official guide to length is one to two years.
Each unit covers one task or skill set that you are assessed on as competent or not yet competent. You finish the qualification when you complete the full set, and the exact set is fixed nationally, whichever provider you choose.

How big it is next to the other levels
Where the rules state a total, the middle value is 12 units for a Certificate II, 16 for a Certificate III, 14 for a Certificate IV and 13 for a Diploma. So a Certificate III is not a small step. The extra depth at higher levels comes from what each unit asks of you, not from the unit count.

Who it suits and what you walk away with
A Certificate III suits people starting in a field, changing fields or stepping up from a Certificate II. Entry requirements vary by qualification and by provider, so check the course page before you enrol. When you finish, you receive a nationally recognised qualification that employers can verify on the national register, and you receive a record of the units you completed along the way.
Core units and electives
Many Certificate III qualifications split their units into core and electives. Core units are the same for everyone. Electives let you tailor the qualification, within rules the training package sets. The Certificate III in Individual Support is a good example. It has 15 units: 9 core and 6 electives.

How long it takes
The Australian Qualifications Framework gives a typical length for a Certificate III of one to two years. That is a guide to the volume of learning, not a promise. Providers can run the same qualification faster or slower, and your own time and any credit for past learning change it too. Part-time and online study usually stretch the time, while full-time study can shorten it.

How you are assessed
Assessment varies by provider, but it often combines a practical demonstration, written questions and evidence from a workplace. You are marked competent or not yet competent for each unit, and if you are not yet competent you can usually try again after more practice. If you have already worked in the field, ask about recognition of prior learning, which can credit skills you already have.
Work placement
Some Certificate III qualifications include work placement. The Individual Support qualification asks for 120 hours of work, as set out in its assessment requirements. Others have none. We show it on each course page so you can check before you enrol.

What changes by provider
The units do not change from one provider to the next. The delivery does. Online or in person, the pace, the support you get, the cost and the way placement is arranged all vary. We list more than 400 providers for the Individual Support qualification, so it is worth comparing a few. Cost also varies by provider and by funding, so compare the full price, not just the headline fee.

Tip
Ask each provider which electives it offers and how placement is arranged. Those two answers shape your experience more than the qualification code does.
