Unit Descriptor

This unit describes the performance outcomes, skills and knowledge required to develop 2-D visual representations and plans for haircut structures.

Application of the Unit

This unit applies to hairdressers who visualise the components of finished haircut structures and use 2-D representations of interior and exterior lines and angles, and the direction of design lines and angles, as aids to planning haircuts.

A person undertaking this role applies discretion and judgement and accepts responsibility for outcomes of own work.

Licensing/Regulatory Information

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.



Employability Skills Information

This unit contains employability skills.

Elements and Performance Criteria Pre-Content

Not applicable.

Elements and Performance Criteria



Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

1. Draw outline shapes.

1.1. Analyse the structural components  of the desired haircut design.

1.2. Produce a simple line drawing showing straight and curved design lines and direction of lines  represented in the finished haircut design.

2. Create haircut plans.

2.1. Identify and illustrate starting point, sectioning and parting pattern for each component of the haircut structure.

2.2. Illustrate degree of lift  and distribution of hair , according to the haircut structure.

2.3. Illustrate the structural graphic  for the haircut plan by drawing lines at 90 degrees to the curve of the head.

2.4. Develop a finished haircut plan that shows soft and hard interior and exterior lines, starting point of haircut, sectioning and parting patterns, degree of lift, distribution of hair and structural graphic.

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

  • interpersonal skills to discuss the finished haircut
  • design skills to interpret and plan the components of the haircut design
  • technical skills to:
  • produce simple line drawings
  • transfer design ideas to paper
  • numeracy skills to:
  • calculate exterior and interior lengths in the haircut structure
  • interpret angles and lines in the haircut structure

Required knowledge 

  • elements and principles of design
  • physical appearance of different haircut structures
  • physical appearance of finished designs
  • geometric principles related to angles and shapes

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the following is essential:

  • analysing and interpreting finished looks and the components of haircut structures
  • developing simple line drawings representing finished haircut designs
  • producing 2-D representations showing interior and exterior design lines, indicating soft or hard lines, starting point of haircut, sectioning and parting patterns, degree of lift, distribution of hair and structural graphic.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • analysis sheets
  • a variety of hair design illustrations and examples with different haircut requirements.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • direct observation of the learner:
  • interpreting illustrations to show haircut technique requirements
  • producing simple line drawings that accurately show:
  • the structural graphic
  • interior and exterior, straight and curved design lines and directions of design lines that are relevant to the desired finished haircut
  • starting points, sectioning and parting patterns
  • degree of lift angles
  • distribution of hair
  • written or verbal questions appropriate to the language and literacy level of the learner to test knowledge which include:
  • elements and principles of design
  • geometric principles related to angles and shapes
  • salon procedures
  • review of portfolios of evidence and third-party reports of on-the-job performance.

Guidance information for assessment 

A unit of competency describes an individual skill but people rarely perform one skill at a time. Many skills are combined on a day-to-day basis in the workplace as part of work processes. This does not mean that each skill described by a unit of competency is pre-requisite to another— they are related skills.

Holistic assessment with other units relevant to the industry sector, salon and job role is recommended, for example:

  • SIHHHCS302A Apply one length or solid haircut structures
  • SIHHHCS303A Apply graduated haircut structures
  • SIHHHCS304A Apply layered haircut structures

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Structural components  may include:

  • solid form
  • graduated form
  • layered form.

Straight and curved design lines and direction of lines  may include:

  • horizontal
  • vertical
  • various angles of diagonal lines
  • interior and exterior lines in the haircut structure.

Degree of lift  may include:

  • natural fall
  • various lifting angles.

Distribution of hair  may include:

  • natural fall
  • hair combed at a 90 degree angle to the base parting
  • shifted distribution.

Structural graphic  may include graphics for:

  • solid form
  • graduation or taper
  • increased layering
  • uniform layering
  • structural combinations.
