Certificate III in Hairdressing (SHB30416) is Australia's nationally recognised hairdressing qualification, listed on training.gov.au in the SHB training package. It is competency-based and requires 28 units of competency (21 core plus 7 electives) - there is no centralised exam, fixed question count or set pass mark. Each unit is assessed as Competent or Not Yet Competent through practical salon demonstration plus knowledge evidence (written and oral questioning, projects, observation) gathered by your RTO or TAFE, usually over about 12 months or via an apprenticeship of up to 3-4 years. This 100-question bank is theory revision for the underpinning knowledge of the units - cutting, colour and lightening chemistry, chemical reformation, hair science, consultation, infection control and WHS. It supports study but does not replace your provider's competency assessment.

1Which haircut structure keeps all the hair at the same length, with no graduation or layering, so the perimeter forms a solid line?
A.One-length (solid) cut
B.Uniform layer cut
C.Graduated bob
D.Long graduation
Explanation: A one-length or solid cut brings all hair to a single perimeter length with 0 degrees of elevation, creating a strong unbroken line such as a classic blunt bob. There is no graduation or internal layering.
2Graduation in haircutting is mainly created by:
A.Cutting with no elevation at all
B.Elevating the hair below 90 degrees to build stacked weight
C.Elevating every section to exactly 180 degrees
D.Point cutting the ends only
Explanation: Graduation is produced by holding and cutting sections at low to medium elevation (above 0 but below 90 degrees), which stacks weight and creates a build-up of length, as seen in a graduated bob. The angle of elevation controls how steep the graduation is.
3Cutting all sections of the hair to the same length at 90 degrees elevation from the head produces which structure?
A.Solid form
B.Uniform (one-length) layers
C.Graduation
D.Disconnection
Explanation: Holding every section straight out at 90 degrees and cutting to a constant length follows the curve of the head and creates uniform layers, giving even movement and no weight build-up.
4When cutting men's hair with the clipper-over-comb technique, the comb's main job is to:
A.Hold hair at a chosen angle and length so the clipper can cut a graduated taper
B.Add chemical product to the hair
C.Permanently straighten the hair
D.Replace the need to disinfect the clippers
Explanation: In clipper-over-comb work the comb lifts and holds the hair at a controlled angle and distance from the scalp, and the clipper removes whatever projects beyond the comb, creating a smooth graduated taper especially around the back and sides.
5Increasing tension on a section of wet hair while cutting tends to:
A.Make the cut line fall longer when the hair dries
B.Make the cut line fall shorter when the hair dries
C.Have no effect on the finished length
D.Permanently lighten the hair
Explanation: Stretching hair under high tension while cutting means it springs back and sits shorter once released and dried. To keep length, especially around the hairline or in curly hair, the stylist uses less tension.
6Thinning (texturising) shears are used mainly to:
A.Remove bulk and blend without changing the overall length much
B.Create a perfectly blunt perimeter line
C.Apply colour evenly
D.Disinfect the cutting station
Explanation: Thinning or texturising shears have one toothed blade so they remove only some strands with each cut, reducing density and bulk and softening blends without removing the whole length. They are not used to set a blunt baseline.
7A guideline (cutting guide) in haircutting is:
A.The first cut length used as a reference to cut all following sections
B.The angle of the scissors to the floor
C.The amount of colour developer mixed
D.The temperature of the blow-dryer
Explanation: The guideline is the initial length the stylist establishes and then matches subsequent sections to, ensuring an even, balanced shape. A travelling guide moves with each section while a stationary guide brings hair back to a fixed point.
8On the International Colour Chart (ICC), the depth number 1 represents which natural shade?
A.Lightest blonde
B.Black
C.Medium brown
D.Light red
Explanation: On the ICC level system, depth runs from 1 (black) to 10 (lightest blonde). The number describes how light or dark the hair is, while a separate tone code after a decimal point describes the colour reflect.
9Approximately what strength of hydrogen peroxide is a 20 volume developer?
A.3%
B.6%
C.9%
D.12%
Explanation: Developer volume measures hydrogen peroxide concentration: 10 volume is about 3%, 20 volume about 6%, 30 volume about 9% and 40 volume about 12%. 20 volume (6%) is the standard developer for grey coverage and about two levels of lift.
10In permanent (oxidation) hair colour, the role of the hydrogen peroxide developer is to:
A.Coat the cuticle with a temporary stain only
B.Provide oxygen that develops the dye molecules and lifts natural pigment inside the cortex
C.Lower the pH so the cuticle stays tightly closed
D.Replace the need for a skin test
Explanation: Hydrogen peroxide is an oxidising agent. Mixed with an alkaline oxidation tint it releases oxygen inside the cortex, which both develops the small colour precursors into large coloured molecules and lifts (oxidises) some natural melanin. This is why permanent colour both lightens and deposits.
