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 describes the underpinning knowledge and skills that must be demonstrated to prove competence. It is essential for assessment and must be read in conjunction with the performance criteria, the range statement and the assessment guidelines of the relevant Training Package.

Overview of assessment

A person who demonstrates competency in this unit of competency must be able to apply knowledge of the use and application of a defined workplace range of tint and high lift tint products for a range of colour outcomes on different clients. Knowledge and skill with regard to relevant legislation and workplace procedures that ensure client and operator comfort, health and safety must also be demonstrated.

Specific evidence requirements

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

knowledge and consistent application of workplace policies, procedures and safe work practices in relation to colour services

consistently applying effective questioning and active listening techniques to consult and negotiate with clients and to ensure client comfort and safety throughout the service

recognising and managing contraindications

reading, accurately interpreting and consistently applying manufacturer's colour charts and product instructions

consistently safe selection, preparation, application, processing and removal of colour products according to manufacturer's instructions and workplace procedures

consistently applying client and operator safety precautions.

Context of assessment

For valid and reliable assessment of this unit, competency should be consistently demonstrated over a period of time and observed by the assessor and/or the technical expert working in partnership with the assessor. The technical expert may include the hairdresser and/or an experienced person at the workplace.

Competency should be demonstrated in the workplace or a simulated workplace environment in a range of situations which may include client interruptions and involvement in other related activities normally expected in the workplace. For further guidance on the use of an appropriate simulated environment, refer to the Assessment Guidelines in this Training Package.

Specific resources for assessment

Competency for this unit should be assessed through access to:

relevant documentation including occupational health and safety legislation and regulations, workplace policy and procedures manuals and manufacturer's product safety data sheets

a salon or simulated salon environment

a workplace colouring range along with manufacturer's colour charts and product instructions

clients with a variety of colour correction requirements.

Relationship to other units

This unit requires an assessment outcome that includes evidence of client consultation, knowledge of the chemical and physical effects of hair colour and lightening colour products on the hair and their safe application. In a workplace environment colour correction is usually integrated with general colour or lightening services.
