The Certificate III in Nail Technology (SHB30321) is Australia's nationally recognised nail-technician qualification, delivered by RTOs and TAFEs under the SHB Training Package. It is competency-based, not a single centralised exam: there is no fixed pass mark or national question count, and learners must be judged 'competent' in all 15 units (10 core plus 5 specialty) through practical demonstration plus knowledge evidence. Core knowledge spans manicure and pedicure, acrylic and gel enhancements, nail art, anatomy and physiology, disorders and contraindications, infection control and chemical safety (including the caution against MMA in nail liquids). This 100-question bank is original theory revision for the qualification's underpinning knowledge, not a copy of any RTO assessment. Course fees vary by provider; check training.gov.au and the RTO for current details.

1During a manicure, which structure should a nail technician never aggressively cut or push back, because damaging it can allow bacteria into the nail unit?
A.The free edge
B.The eponychium (living cuticle)
C.The nail plate surface
D.The lateral nail wall
Explanation: The eponychium is the living skin seal at the base of the nail that protects the matrix from pathogens. It should only be gently pushed back, not cut, because breaking this seal can introduce bacteria and cause infection such as paronychia.
2What is the main purpose of applying a base coat before coloured nail polish in a manicure?
A.To speed up drying of the colour
B.To protect the natural nail from staining and improve polish adhesion
C.To remove surface oils from the skin
D.To disinfect the nail plate
Explanation: A base coat creates a smooth, adhesive layer that helps coloured polish grip the nail and prevents pigments (especially dark or red shades) from staining the keratin of the nail plate.
3Why should a pedicure foot soak generally not be excessively long or very hot for a client?
A.It makes polish dry faster
B.It can over-soften and macerate the skin and dehydrate it, and excessive heat is unsafe for some clients
C.It removes the lunula
D.It hardens the nail plate permanently
Explanation: Prolonged or very hot soaking macerates and dehydrates the skin and can be unsafe for clients with reduced sensation or circulation. A warm, moderate soak softens skin and cuticles enough for safe pedicure work.
4When filing a natural nail's free edge, why is it best practice to file in one direction rather than using a back-and-forth sawing motion?
A.It is faster
B.Back-and-forth filing generates heat and can split or peel the nail layers
C.One-directional filing sterilises the file
D.It makes the nail grow faster
Explanation: A back-and-forth sawing motion frays and separates the keratin layers of the nail plate, causing splitting and peeling. Filing in one direction from the side toward the centre keeps the edge smooth and the layers intact.
5A client requests a hand and arm massage as part of a manicure. Which client condition would be a contraindication to massage and require referral or avoidance of that area?
A.Slightly dry skin
B.A recent unhealed cut, swelling, or signs of infection on the hand
C.Short natural nails
D.A preference for pale polish
Explanation: Open or unhealed cuts, swelling, bruising, or signs of infection are contraindications to massage because pressure and friction can spread infection or worsen injury. The technician should avoid the area or refer the client.
6What is the recommended nail shape consideration for a client with wide nail beds who wants the nails to appear narrower and longer?
A.A very wide square shape
B.An oval or almond shape that creates a slimming visual line
C.A flat straight-across cut at skin level
D.Removing the side walls of the nail
Explanation: Oval and almond shapes taper toward the tip and create a vertical line that visually narrows and lengthens a wide nail bed. Square shapes emphasise width.
7Why should toenails generally be cut and filed straight across rather than rounded deeply at the corners?
A.It looks more fashionable
B.Rounding the corners deeply increases the risk of an ingrown toenail (onychocryptosis)
C.Straight nails grow faster
D.It uses less polish
Explanation: Cutting toenail corners too short or rounding them deeply allows the nail to grow into the surrounding skin, causing onychocryptosis (ingrown toenail). A straight-across edge, lightly smoothed, reduces this risk.
8What is the function of cuticle remover (cuticle softener) used during a manicure?
A.To dissolve the nail plate
B.To soften and loosen dead tissue (pterygium) on the nail plate so it can be gently pushed back
C.To harden the free edge
D.To cure gel polish
Explanation: Cuticle remover contains mild alkaline ingredients that soften and loosen the non-living dead skin (pterygium) clinging to the nail plate so it can be gently eased back, making cuticle work safer and easier.
9A client's natural nails are very thin and flexible. Which manicure recommendation is most appropriate to strengthen them over time?
A.Buff the surface heavily at every visit
B.Recommend a nail strengthener/hardener and gentle, minimal filing
C.Soak the nails in acetone daily
D.Apply MMA acrylic for thickness
Explanation: Thin, weak nails benefit from a strengthening treatment and minimal mechanical stress. Heavy buffing thins them further, and harsh chemicals like daily acetone or MMA worsen damage.
10Before beginning any manicure or pedicure, what should the nail technician always carry out first?
A.Apply top coat
B.A client consultation and nail/skin analysis to identify needs and contraindications
C.Cure the nails under a lamp
D.Buff the nails to a high shine
Explanation: A consultation and visual analysis of the nails and skin identify the client's needs, any contraindications, and the most suitable service and products. This step protects both client and technician and is required before treatment.
