How many questions are on the carpenter trade test?

NAMB does not publish a fixed multiple-choice question count. The trade test is competency-based, combining practical tasks with underpinning trade theory, and gives a Competent or Not Yet Competent result. This free bank gives you 100 trade-theory practice questions to prepare.

What are the requirements to write the carpenter trade test?

Candidates typically need an N2 Certificate with the relevant carpentry trade-theory subjects plus relevant workplace experience, or a completed learnership/apprenticeship. You then apply through a NAMB-accredited trade test centre.

Which standards should I study for South African roof carpentry?

Study SANS 10400 Part L (Roofs) for the deemed-to-satisfy roof requirements, SANS 10082 for timber buildings, and SANS 10243 for the manufacture and erection of nail-plated timber trusses. Use SANS standards, not BS or US codes.

Is this free carpenter trade test practice useful for the real assessment?

Yes. The 100 practice questions cover the underpinning trade theory examiners expect, using correct South African terminology and SANS references, with a teaching explanation for every answer plus a free AI tutor. All content is free forever and updated for 2026.

The South Africa Carpenter artisan trade test is the national assessment for qualifying as a carpenter, conducted at a NAMB-accredited trade test centre under the Quality Council for Trades and Occupations (QCTO). It is competency-based, combining practical carpentry tasks with underpinning trade theory, and results in a Competent or Not Yet Competent decision rather than a published percentage. Candidates usually hold an N2 Certificate with the relevant carpentry trade-theory subjects plus relevant workplace experience. The theory covers timber and materials, joints and joinery, roof carpentry and trusses, formwork and shuttering, doors and windows, drawing interpretation, and safety, all grounded in South African SANS standards (SANS 10400-L, SANS 10082, SANS 10243). This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Which softwood is most commonly used for structural roof timbers in South African building construction?

A.Saligna (eucalyptus)

B.SA pine (Pinus species)

C.Imported oak

D.Meranti hardwood

Explanation: SA pine (Pinus patula, P. elliottii and P. radiata) is the standard structural softwood for roof carpentry in South Africa. It is graded for strength, relatively light, readily available and economical, which is why SANS 10082 and SANS 10400-L span tables are based on it.

2On graded South African structural pine, what does a grade stamp of 'S5' indicate?

A.A moisture content of 5%

B.A stress grade with defined allowable design stresses (the lowest of the common structural grades)

C.Timber 5 years old

D.A board 5 mm thick

Explanation: S5, S7 and S10 are the commercial stress grades for SA pine, defined by their allowable design stresses and strength properties. S5 is the most common structural grade for roof timbers; S7 and S10 are stronger grades used where higher loads or longer spans demand it.

3What is the typical target moisture content for kiln-dried structural SA pine used in roof construction?

A.Around 0-5%

B.Around 12-18%

C.Around 30-40%

D.Around 50%

Explanation: Structural SA pine is dried to roughly 12-18% moisture content so it stabilises close to equilibrium with normal in-service conditions. This minimises shrinkage, warping and movement after the roof is erected.

4Why is timber seasoned (dried) before it is used in construction?

A.To increase its weight

B.To reduce moisture so it is more stable, stronger and less prone to shrinkage, warping and decay

C.To make it darker in colour

D.To make it burn more easily

Explanation: Seasoning lowers the moisture content towards the in-service equilibrium, which increases strength and stiffness, reduces shrinkage and distortion, improves the holding of nails and fixings, and makes the timber less susceptible to fungal decay and insect attack.

5A timber defect where the board curves along its length, lifting the ends or middle, is best described as:

A.Bow

B.Shake

C.Wane

D.Knot

Explanation: Bow is a curvature along the length of a board in the plane of its face, usually caused by uneven drying or growth stresses. Recognising distortion defects (bow, spring/crook, cup and twist) lets a carpenter reject or correctly orientate timber.

6What is the main purpose of CCA (chromated copper arsenate) treatment of SA pine roof timbers?

A.To make the timber heavier

B.To protect it against fungal decay and insect/borer attack

C.To increase its moisture content

D.To change its stress grade

Explanation: CCA and similar preservative treatments protect SA pine against wood-destroying fungi, termites and wood borers, which is important because untreated pine sapwood is highly susceptible. Treated structural timber is widely specified for roof structures, with the green tinge identifying CCA-treated timber.

7Which sheet material is manufactured from thin veneers of wood glued with the grain of adjacent layers at right angles?

A.Chipboard (particle board)

B.Plywood

C.Hardboard

D.Fibre-cement board

Explanation: Plywood is built up from an odd number of veneers (plies) glued so that the grain of each layer runs at right angles to the next. This cross-banding gives plywood strength in both directions and dimensional stability, making it useful for formwork, gussets and panelling.

8A type of adhesive suitable for exterior structural use because it is fully waterproof and gap-filling is:

A.PVA wood glue (interior grade)

B.Resorcinol-formaldehyde (RF) or phenol-based resin

C.Animal/hide glue

D.Wallpaper paste

Explanation: Resorcinol-formaldehyde and phenolic resin adhesives are weatherproof and used for structural and exterior glued timber such as laminated members and marine plywood. Standard interior PVA is not fully waterproof and is unsuitable for exposed structural work.

9In a softwood log, which part is generally more durable and contains fewer living cells?

A.Sapwood

B.Heartwood

C.Cambium

D.Bark

Explanation: Heartwood is the older, central wood whose cells are no longer conducting sap; it is generally darker, denser and more naturally durable than the outer sapwood. Sapwood is lighter and more susceptible to decay and borer, which is why treatment focuses on protecting it.

10What does 'PAR' mean when ordering SA pine timber such as 'PAR pine'?

A.Pressure-Applied Resin

B.Planed All Round (dressed on all four faces)

C.Pine At Random length

D.Preservative Anti-Rot

Explanation: PAR stands for Planed All Round, meaning the timber has been dressed (planed) on all four faces to a smooth, finished section. PAR sizes are smaller than the sawn nominal size because planing removes material, which matters when setting out joinery.
