Certificate III in Scaffolding (CPC30920) is Australia's nationally recognised scaffolding trade qualification, delivered by RTOs under ASQA. It carries the SafeWork High Risk Work Licence classes - Basic (SB), Intermediate (SI) and Advanced (SA) - which authorise erecting, altering and dismantling scaffolds where a person or object could fall more than 4 metres. Because it is competency-based, there is no single fixed national exam: each licence class is assessed with a multiple-choice knowledge test (commonly ~80% to pass) plus a practical performance assessment, all built on AS/NZS 1576, AS 4576 and the WHS scaffolding codes of practice. Content spans scaffold types and components, load ratings and safe working loads, erection and dismantling sequence, ties and bracing, edge protection, SWMS and risk control. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Under Australian WHS law, at what fall distance does erecting, altering or dismantling a scaffold require a person to hold a High Risk Work Licence (HRWL)?
A.More than 1 metre
B.More than 2 metres
C.More than 3 metres
D.More than 4 metres
Explanation: Scaffolding work is defined as erecting, altering or dismantling a temporary structure supporting a platform from which a person or object could fall MORE THAN 4 metres. Only that work requires a scaffolding HRWL (SB, SI or SA). Below 4 metres the work may be done by a competent person without a scaffolding licence.
2Which scaffolding High Risk Work Licence class covers ONLY modular or prefabricated scaffolds, cantilevered materials hoists up to 500 kg, ropes, gin wheels and safety nets?
A.Basic scaffolding (SB)
B.Intermediate scaffolding (SI)
C.Advanced scaffolding (SA)
D.Restricted scaffolding (SR)
Explanation: Basic scaffolding (SB) is the entry class. Its scope is modular/prefabricated scaffolds, cantilevered materials hoists with a maximum working load of 500 kg, ropes, gin wheels, safety nets and static lines, and bracket scaffolds. Higher work needs SI or SA.
3A scaffolder needs to erect a tube-and-coupler scaffold and cantilevered crane loading platforms. What is the MINIMUM scaffolding HRWL class required?
A.Basic scaffolding (SB)
B.Intermediate scaffolding (SI)
C.Advanced scaffolding (SA)
D.Dogging (DG)
Explanation: Intermediate scaffolding (SI) covers all basic work PLUS tube-and-coupler scaffolds, cantilevered crane loading platforms, cantilevered and spur scaffolds, barrow ramps, sloping platforms, mast climbing work platforms and perimeter safety screens. SB alone is not sufficient for tube-and-coupler erection.
4Which type of scaffolding work can ONLY be performed by the holder of an Advanced scaffolding (SA) licence?
A.Erecting a prefabricated modular scaffold
B.Erecting a tube-and-coupler gantry
C.Erecting hung and suspended scaffolds
D.Erecting a barrow ramp
Explanation: Advanced scaffolding (SA) is the highest class and uniquely covers hung scaffolds (hung from tubes, wire ropes or chains), suspended (swing-stage) scaffolds and cantilevered hoists. SA holders can also do all SB and SI work.
5What is the maximum live load per platform per bay for a LIGHT duty working platform under the Australian scaffolding duty ratings?
A.225 kg
B.450 kg
C.675 kg
D.900 kg
Explanation: Light duty platforms are rated to a maximum live load of 225 kg per platform per bay (including a 120 kg concentrated load) and are used for light tasks such as painting, electrical and carpentry. The minimum platform width for light duty is 450 mm.
6A bricklaying gang needs a scaffold platform. Which duty rating is appropriate and what is its maximum live load per bay?
A.Light duty, 225 kg
B.Medium duty, 450 kg
C.Heavy duty, 675 kg
D.Special duty, 1000 kg
Explanation: Bricklaying and demolition are classic HEAVY duty tasks. Heavy duty platforms are rated to 675 kg live load per bay (including a 200 kg concentrated load) and require a minimum platform width of 900 mm to carry the stacked bricks and mortar.
7Which Australian Standard SERIES specifies the performance and design requirements for scaffolding equipment and components?
A.AS/NZS 3000
B.AS/NZS 1576
C.AS/NZS 4576
D.AS 3600
Explanation: The AS/NZS 1576 series (Parts 1 to 6) sets the performance and structural-design requirements for scaffolding and scaffold components. Scaffold equipment used at a workplace must comply with the relevant parts of AS/NZS 1576.
8What is the role of AS 4576 (Guidelines for scaffolding) compared with the AS/NZS 1576 series?
A.It sets the manufacturing tolerances for couplers
B.It gives practical guidance on selecting, erecting, using and dismantling scaffolds
C.It specifies electrical earthing for scaffolds
D.It is the licensing law for scaffolders
Explanation: AS 4576 (Guidelines for scaffolding, latest 2020 edition) gives practical guidance on training scaffolders and on the safe selection, supply, erection, alteration, dismantling, maintenance, inspection and use of scaffolding. AS/NZS 1576 is the equipment/design performance standard the guidelines refer back to.
9In Australian WHS terms, what is a 'dead load' on a scaffold?
A.The weight of workers and materials
B.The self-weight of the scaffold structure and its permanent components
C.Wind and impact forces
D.The maximum load the scaffold may carry
Explanation: Dead loads are the self-weight of the scaffold structure and its components: standards, ledgers, transoms, platforms, stairs, screens, sheeting, ties, hoists and cables. Dead loads are calculated in accordance with AS/NZS 1576.1. Live loads (people, materials, tools, impact) are separate.
10On a scaffold, which component is the vertical load-bearing tube that transfers loads down to the base plate and sole board?
A.Ledger
B.Transom
C.Standard
D.Putlog
Explanation: A standard (also called an upright) is the vertical tube that carries the scaffold's load down to the base plate and sole board on the ground. Ledgers are horizontal longitudinal tubes; transoms run across the standards and support the platform.

Frequently Asked Questions

Is there a single exam for Certificate III in Scaffolding (CPC30920)?

No. CPC30920 is a competency-based VET qualification with no single fixed national exam. Its scaffolding High Risk Work Licence classes (Basic SB, Intermediate SI, Advanced SA) are each assessed with a multiple-choice knowledge test plus a practical performance assessment, with formats set by the RTO.

What scaffolding licence do I need, and when is it required?

You need a scaffolding High Risk Work Licence to erect, alter or dismantle a scaffold from which a person or object could fall more than 4 metres. There are three classes: Basic (SB), Intermediate (SI) and Advanced (SA), and you must hold the lower class before progressing to the next.

What is the difference between SB, SI and SA scaffolding licences?

Basic (SB) covers modular/prefabricated scaffolds and basic equipment. Intermediate (SI) adds tube-and-coupler scaffolds, cantilevered and spur scaffolds, loading platforms and mast climbers. Advanced (SA) is the highest class and adds hung and suspended (swing-stage) scaffolds and cantilevered hoists.

What standards does Australian scaffolding work follow?

Scaffold equipment must comply with the AS/NZS 1576 series (Parts 1-6), and AS 4576 provides guidelines for scaffolding. Work is also governed by the WHS Regulations and the state scaffolding and managing-falls codes of practice.

How often must a scaffold over 4 metres be inspected?

A scaffold over 4 metres must be inspected by a competent person at least every 30 days, and additionally after any alteration, repair or event (such as a storm) that could affect its safety. A handover certificate and Scafftag confirm it is safe to use.

Is this free scaffolding practice as good as paid prep?

Our 100 practice questions cover the same trade-theory knowledge tested in the SB, SI and SA licence assessments, with a teaching explanation for every answer plus free daily AI tutor interactions. All content is free forever and updated for 2026.
