OpenExamPrep

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.

Sample Cert III Hairdressing Practice Questions

Try these sample questions to review concepts for the Cert III Hairdressing exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

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.

About the Cert III Hairdressing Exam

Certificate III in Hairdressing (SHB30416) is the nationally recognised Australian vocational qualification for hairdressers, listed on training.gov.au within the SHB Hairdressing and Beauty Services Training Package. It reflects the role of hairdressers who use well-developed consultation, sales and technical skills to deliver cutting, colouring, lightening, chemical reformation, styling and treatment services in a salon. The qualification is made up of 28 units of competency (21 core plus 7 electives) and is assessed in a competency-based way: there is no single national exam or fixed pass mark. Instead, RTOs and TAFEs gather evidence through practical demonstration in a real or simulated salon plus knowledge evidence such as written and oral questioning. This practice bank is theory revision for the underpinning knowledge of those units; it does not replace your RTO's assessment.

Exam sponsor: Delivered by Registered Training Organisations (RTOs) and TAFE institutes; the qualification is maintained on the national VET register at training.gov.au.. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

SHB30416 requires 28 units of competency: 21 core units plus 7 electives. Each unit is assessed as Competent or Not Yet Competent through practical demonstration plus knowledge evidence; there is no single multiple-choice exam.

Time Limit

No fixed exam time. The qualification is typically delivered over about 12 months full-time, or up to 3-4 years via an apprenticeship; knowledge assessments are scheduled by the RTO.

Passing Score

There is no centralised pass mark. Learners must be deemed Competent in all 28 units (21 core + 7 electives) to be awarded the qualification.

Exam / Certification Fees

No single national exam fee. Course fees are set by each RTO/TAFE and depend on funding; fee-for-service delivery is commonly several thousand to about AUD 15,000, while apprenticeship and subsidised places cost much less.

Exam sponsor website

Fees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.

Our practice resources: topics covered

We aim to reflect publicly available exam outlines and topic information in our study resources. Coverage, format, and difficulty may differ from the actual exam, and we cannot guarantee that every detail is accurate or current.

20%

Cutting techniques and design

Underpinning knowledge for designing and creating haircut structures: one-length/solid, graduated and layered cuts, over-comb and clipper work. Covers head shape, reference points, sectioning, elevation/projection, cutting angles, guidelines, tension, weight distribution and tool selection (scissors, thinning shears, razor, clippers).

22%

Colour and lightening

Oxidation (permanent) colour chemistry and how dye precursors develop in the cortex; the International Colour Chart system of depth (levels 1-10) and tone; developer strengths (10 vol = 3%, 20 vol = 6%, 30 vol = 9%, 40 vol = 12% hydrogen peroxide) and levels of lift; full-head and highlighting/foil bleach work, on-scalp bleach safety, toning, and neutralising unwanted tones using the colour wheel.

12%

Chemical reformation

Perming, straightening and relaxing chemistry. Reducing agents such as ammonium thioglycolate break the keratin disulfide (cystine) bonds; the hair is reshaped, then a neutraliser (an oxidising agent such as hydrogen peroxide or sodium bromate) reforms the bonds in the new shape. Covers alkaline vs acid perms, sodium hydroxide (lye) and thio/no-lye relaxers, pH, processing controls and strand testing.

14%

Hair and scalp science

Hair and skin structure: the protein keratin, the cuticle, cortex and medulla, and the bonds (disulfide, hydrogen, salt) that give hair strength and shape. Covers the hair growth cycle (anagen, catagen, telogen), porosity, elasticity, density and texture, and common hair and scalp conditions and how they affect technical services.

16%

Consultation, styling and shampooing

Client consultation and record-keeping, head and face shape analysis to recommend suitable shapes, shampoo and basin services and scalp massage, water temperature and product selection, and blow-drying and styling using the temporary breaking and reforming of hydrogen bonds.

16%

Infection control, WHS and salon operations

Hygiene and infection prevention and control, cleaning, disinfection and sterilisation of tools, hazardous chemicals and safety data sheets (SDS), personal protective equipment, work health and safety duties, environmentally sustainable work practices, patch and skin tests, and salon service standards and financial transactions.

Cert III Hairdressing: Suggested Study Strategy

1Map your revision to the units of competency on training.gov.au - cutting (SHBHCUT), colour and lightening (SHBHCLS), reformation (SHBHREF), styling (SHBHDES) and WHS (SHBXWHS) - so you cover every knowledge area your RTO assesses.
2Learn the developer table cold: 10 vol = 3%, 20 vol = 6%, 30 vol = 9%, 40 vol = 12% hydrogen peroxide, and remember higher volume means more lift but more damage.
3Use the colour wheel for neutralising: green cancels red, blue cancels orange and violet cancels yellow - the basis for toning brassy tones after lightening.
4Understand the disulfide-bond story for perms and relaxers: a reducing agent breaks the bonds, the hair is reshaped, and a neutraliser (oxidiser) reforms them - missing the neutralising step ruins the result.
5Connect science to technique: knowing the cuticle, cortex and the hair growth cycle helps you explain porosity, why colour is deposited in the cortex, and why blow-dry sets are only temporary.
6Always link safety to practice: patch/skin tests before colour, strand tests before chemical services, reading the SDS for hazardous chemicals, and disinfecting tools between clients.

Frequently Asked Questions

Is there a single exam for Certificate III in Hairdressing?

No. SHB30416 is competency-based and assessed by your RTO or TAFE through practical demonstration plus knowledge evidence. There is no centralised national exam, fixed question count or set pass mark - you must be deemed Competent in all 28 units.

How many units of competency are in SHB30416?

28 units must be completed: 21 core units plus 7 electives. The electives are chosen from packaging-rule groups to suit the job outcome, with general or men's hairdressing streams plus additional Group C units.

Do these practice questions replace my RTO assessment?

No. These are original theory-revision questions covering the underpinning knowledge of the units. Your RTO assesses competency through observed practical work and its own knowledge evidence; this bank only supports your study.

What does each developer volume mean?

Developer volume measures hydrogen peroxide strength: 10 volume is about 3%, 20 volume about 6%, 30 volume about 9% and 40 volume about 12%. Higher volumes give more lift but are harsher, so 20 volume is the usual maximum on-scalp with bleach.

How long does the qualification take?

Full-time delivery is often about 12 months, but most people complete SHB30416 as a hairdressing apprenticeship over roughly 3 to 4 years, combining off-the-job training at an RTO with supervised salon work.

Are there entry requirements?

training.gov.au lists no entry requirements for SHB30416, and no occupational licence is required for the qualification itself. Individual RTOs may set their own language, literacy, numeracy or pre-enrolment expectations.
