Key takeaways
- The same three qualifications work everywhere: Certificate IV in Building and Construction (CPC40120) for low-rise, Diploma of Building and Construction (Building) (CPC50220) for medium-rise, and Advanced Diploma of Building and Construction (Management) (CPC60220) for open and unlimited work.
- There is no national builder licence. Eight state and territory regulators each issue their own licence class with their own experience period and gatekeeping test, so the qualification is the portable part and the licence is the local part.
- The clean ladder breaks in two places: in Victoria the Cert IV is not a prescribed course for any class, and in the Northern Territory the Cert IV covers residential building right up to the unrestricted class.
- Experienced tradies do not start over. Recognition of Prior Learning converts documented experience into the same Cert IV or Diploma by assessment, and Western Australia names RPL as a formal registration route in its own regulations.
- Holding a qualification is not the same as holding a licence. Every state adds supervised experience of two to seven years plus a net-asset test, insurance, a written exam or an interview.
The national ladder
The three qualifications and what each lets you build
One academic ladder, three rungs, the same scope of work whether you study in Perth or Brisbane.
Three nationally recognised qualifications form the building and construction management ladder. The Certificate IV in Building and Construction (CPC40120) covers low-rise work, the Diploma of Building and Construction (Building) (CPC50220) covers medium-rise up to about three storeys, and the Advanced Diploma of Building and Construction (Management) (CPC60220) covers open and unlimited high-rise and commercial work. All three are listed as current on training.gov.au.
The capability each qualification represents does not move across borders. A Diploma means the same thing as a credential in every state. What moves is the licence it points at and the experience a regulator wants to see behind it. Get the codes right and the rest of this guide falls into place.
The three CPC building and construction qualifications
| Qualification | Code | AQF level | Scope of work |
|---|---|---|---|
| Certificate IV in Building and Construction | CPC40120 | AQF 4 | Low-rise: Class 1 and 10 to two storeys, Class 2-9 Type C |
| Diploma of Building and Construction (Building) | CPC50220 | AQF 5 | Medium-rise: up to around three storeys, Type B and C |
| Advanced Diploma of Building and Construction (Management) | CPC60220 | AQF 6 | Open and unlimited: all classes, Type A, high-rise |
⚠️
Mind the code
The Advanced Diploma of Building and Construction (Management) is CPC60220. CPC60121 is a different qualification entirely (Advanced Diploma of Building Surveying), so if you see that code on a management pathway it is the wrong one. The Certificate IV is titled simply “Certificate IV in Building and Construction” with no “(Building)” suffix, though many providers still informally add it.
The qualification ladder
How it works
What each rung opens up
- Cert IV (CPC40120): the entry rung, low-rise building, 19 units (11 core plus 8 elective).
- Diploma (CPC50220): the middle rung, medium-rise and registered-builder work.
- Advanced Diploma (CPC60220): the top rung, open and unlimited construction management.
If you are weighing one rung against the next, our Certificate IV in Building and Construction and Diploma of Building and Construction course pages set out the units and study options for each, and the Advanced Diploma page covers the open-class management qualification.
Portable vs local
What stays the same everywhere and what changes
The qualification is the nationally portable part. The licence is the locally issued part.
The qualification is the part that travels. A Certificate IV, Diploma or Advanced Diploma of Building and Construction is nationally recognised and accepted by every Australian regulator. The licence is the part that stays local: there is no national builder licence, so eight separate state and territory regulators each issue their own licence class with their own experience period and their own gatekeeping test on top of the same qualification.
In practice that means the course you need barely changes when you cross a border. The experience the regulator wants and the process it runs do. The CPC50220 Diploma points at a QBCC “Builder - Medium Rise” licence in Queensland, a general building licence in NSW with two years of experience inside the last ten, and a Set 1 registration in Western Australia that asks for seven years.
- Same everywhere: the qualification code, the units, and the scope of work it represents
- Changes by state: the licence class name and what work it authorises
- Changes by state: the years of supervised experience required, from two to seven
- Changes by state: the gatekeeping test (net assets, insurance, written exam or interview)
One qualification, eight licences
The split
Read it this way
- The qualification you earn once is recognised in all eight jurisdictions.
- Each regulator then issues its own licence class against that qualification.
- So “what course do I need” has a national answer; “what licence do I get” has eight.
The line that matters
Holding a qualification is not the same as holding a licence. The qualification satisfies the education component. The licence still needs experience and a gatekeeping test, and a wrong assumption here is the difference between a valid application and a rejected one.
The matrix
State by state: your regulator and licence class
The same three qualifications held constant, overlaid against all eight regulators.
Each Australian state and territory has its own building regulator and its own builder licence classes. Queensland uses the QBCC, NSW the NSW Building Commission, Victoria the new Building and Plumbing Commission, South Australia Consumer and Business Services, Western Australia the Building Services Board, Tasmania CBOS, the ACT Access Canberra, and the Northern Territory the Building Practitioners Board. The matrix below maps each qualification to the licence it unlocks in every one.

Years of experience and the gatekeeping test each regulator applies
| State | Experience | Gatekeeping test |
|---|---|---|
| QLD | 2yr (trade) / 4yr (no trade) | Net-asset test for contractors; home-warranty insurance |
| NSW | 2yr within the last 10yr | Home building compensation cover; no net-asset test, no written exam |
| VIC | DB-L 2yr / DB-U 3yr | BPC exam; domestic building insurance |
| SA | 4yr (apprenticeship) / 5yr (Cert IV) | Around $10k net assets (contractor); technical interview (supervisor) |
| WA | 5yr / 7yr by Set | Board exams or RTO RPL assessment (Set 4 / 5) |
| TAS | 2yr-4yr; 3yr-6yr for Open | Indemnity insurance and CPD; no exam, no net-asset test |
| ACT | 2yr, at least 1yr post-qualification | 80% pass on a written exam for Classes A, B and C |
| NT | 3yr, 1yr in the NT, within 10yr | $50k net tangible assets; fit-and-proper check |
💡
The contractor vs supervisor split
In several states the licence is two things, not one. A contractor licence lets you sign building contracts and carries the financial test, while a supervisor licence or registration holds the qualification and supervises work but cannot contract on its own. Queensland runs a three-way split (Contractor, Nominee Supervisor, Site Supervisor) where the Site Supervisor sub-licence needs the qualification but no experience. South Australia legally separates the Building Work Contractor Licence from the Building Work Supervisor Registration, and a sole trader needs both.
Confirm the dollar figures
Net-asset floors such as roughly $10,000 in South Australia, around $12,000 in Queensland and $50,000 in the Northern Territory are floors that scale with turnover, not fixed national numbers. Always confirm the current figure with your regulator before you apply, because the full scaling tables sit behind each authority’s financial-requirements policy.
For the state-specific detail behind these rows, our QBCC licence guide, NSW builder licence guide and How to Become a Builder in Australia guide walk through each application in order.
The two gotchas
Where the rule of thumb breaks: Victoria and the NT
The clean Cert IV equals low-rise rule is true in five jurisdictions and breaks in two, in opposite directions.
The tidy “Cert IV equals low-rise, Diploma equals medium, Advanced Diploma equals open” rule holds cleanly in Queensland, Tasmania and the ACT and broadly in NSW and South Australia. Two jurisdictions break it. In Victoria the Certificate IV is not a prescribed course for any builder class. In the Northern Territory the Certificate IV covers residential building right up to the unrestricted class. A reader who assumes one course means one licence everywhere is wrong on both counts.

Jurisdictions where the ladder runs clean
VIC
Cert IV not prescribed for any class
NT
Cert IV covers the unrestricted class
⚠️
Victoria: the Cert IV does not register you on its own
Under the Victorian building regulations the Certificate IV (CPC40120) is not a prescribed course for any class of builder registration. The Building and Plumbing Commission treats it as covering only part of the knowledge requirement, so a Cert IV holder in Victoria must sit additional BPC exams to register. The same Cert IV that is a clean licence key in five states is an exam-gated credential in Victoria.
💡
Northern Territory: the Cert IV stretches further than you think
In the NT the Certificate IV anchors residential building for both the restricted and the unrestricted (over-two-storey) class. The Territory differentiates by demonstrated knowledge and experience rather than by a higher qualification, so an experienced residential builder does not necessarily need to step up to the Diploma to take on unrestricted residential work.
Victoria’s outlier status has a moving part too. The Victorian Building Authority was absorbed into the Building and Plumbing Commission on 1 July 2025, and the BPC online-exam transition is due to complete around mid-2026, so confirm the current exam logistics directly. Our Victorian builder registration guide carries the ladder-break detail in full.

Study first or RPL
Two ways in: study first or RPL
Both routes end at the same nationally recognised qualification.
There are two ways into a building qualification, and they end at the same place. A no-experience entrant takes the study-first route, completing the Certificate IV or Diploma through coursework and then building the supervised experience their state requires. An experienced tradie takes the Recognition of Prior Learning route, where an assessor converts documented on-the-tools experience directly into the same qualification without classroom re-study. Both produce an identical, nationally recognised certificate.
From qualification to builder licence: the five steps
1
▼
Pick the qualification for the work you want to do
Certificate IV (CPC40120) for low-rise, Diploma (CPC50220) for medium-rise, or Advanced Diploma (CPC60220) for open and unlimited work.
2
▼
Choose your route in
Study first if you are new to the industry, or use RPL if you already have years of documented experience on the tools.
3
▼
Build the experience your state requires
Accumulate the supervised experience your regulator asks for, between two and seven years depending on the jurisdiction and class.
4
▼
Confirm your licence class and gatekeeping test
Check the matrix for your regulator, the class your qualification unlocks, and any net-asset test, insurance, written exam or interview.
5
Apply to your state or territory regulator
Lodge your application with the relevant building authority, attaching your qualification, experience evidence and financial documents.
- Choose the qualification that matches the work you want to be licensed for.
- Choose study-first or RPL based on how much documented experience you already have.
- Build the supervised experience your state requires, two to seven years.
- Confirm the licence class and gatekeeping test for your regulator.
- Apply to your state or territory regulator with qualification and experience evidence.
Two routes, one qualification
How it works
Which route is yours
- Study first: for career-changers and new entrants with little or no construction experience.
- RPL: for licensed or experienced tradies, chippies, brickies and concreters stepping up to a builder licence.
- Same finish line: both end at the identical CPC qualification a regulator accepts.
RPL for experienced tradies
RPL is an assessment, not a course. Your years of documented work, site photos, payslips and reference letters feed directly into an evidence portfolio that an assessor maps against the units of the Certificate IV or Diploma. Every regulator accepts an RPL-derived qualification identically to a studied one, and Western Australia goes furthest by naming RTO RPL assessment as a formal Set 4 registration route equal to the Diploma in its own regulations.
The RPL evidence kit
What you bring
Evidence that counts toward RPL
- Photos of work you have completed on site
- Payslips, contracts and tax records showing your trade history
- Reference letters from builders and supervisors
- Your existing trade certificate and licences
If you have been on the tools for years, the RPL for building and construction guide explains how to gather evidence, and the Certificate IV course page shows how RPL can shorten the path to a low-rise builder licence.
General information, confirm before you apply
This guide is general information about nationally recognised qualifications and the licence classes they can contribute to. Licence class names, experience periods and fees are set by each state and territory regulator and change over time. Always confirm current requirements with your relevant building authority before applying, and remember that holding a qualification does not by itself guarantee a licence.
