Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

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

knowledge of the main ingredients in common hairdressing products and their physical and chemical effects on hair

applying safe work practices and the safe use of products and equipment (including the use of preventative measures)

knowledge and consistent application of the principles of skin and hair science as they apply to hairdressing services, including:

main functions and roles of the skin

structural and cellular features of hair and hair follicles

process of hair growth and the hair growth cycle

characteristics of normal and damaged hair

contraindications to particular services.

Context of and specific resources for assessment

Assessment must ensure access to:

a salon or a simulated salon environment that includes a range of work situations such as client interruptions and involvement in other related activities normally expected in the salon

a fully equipped salon which includes as a minimum:

a fully functional client reception area with:

telephone

client booking system

retail products range

a basin services area

equipment and work stations suitable for services including:

client consultation

hair and scalp treatments

haircutting

hair design

hair colouring

hair lightening

reformation

a supply of clean towels

a supply of clean client gowns or wraps

hairdressing products and equipment

a range of clients for different services

relevant documentation, such as:

product information and safety data sheets

salon procedures.

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:

observation of the learner:

performing consultation, and hair and scalp analysis

safely performing a variety of treatment processes with minimum negative impact on hair and skin.

written or verbal questions appropriate to the language and literacy level of the learner to test knowledge which may include:

structural and cellular features of the hair and hair follicles

hair growth cycle

hair colour

effects of chemical curling, volumising and straightening products on the structure of the hair

relationship between the pre-existing condition of the hair and scalp and the contraindication of some services

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:

SIHHOHS201A Apply salon safety procedures

SIHHHSC302A Identify and treat hair and scalp conditions

Required Skills and Knowledge

Required skills

communication skills to respond to questions and provide information, advice and reassurance to clients on hairdressing services

technical skills to:

analyse client hair characteristics

select products and services that will minimise hair damage

protect client and operator skin

literacy skills to interpret:

relevant information on skin and hair biology

product information and safety data sheets

Required knowledge

relevant health and hygiene regulations

skin penetration legislation and regulations

relevant occupational health and safety legislation and regulations

principles of hairdressing science as they relate to hairdressing treatments

salon procedures related to the performance of hairdressing services

skin biology in relation to scalp treatments and procedures

hair biology in relation to common hairdressing treatments

the salon product range.
