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 broad range of products to solve complex colour problems on different clients This will take the form of working in a team to provide technical advice to other operators on colour correction strategies and techniques Knowledge of and skill in applying 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 manufacturers colour charts and product instructions

consistently safe selection preparation application processing and removal of colour according to manufacturers instructions and workplace procedures

consistently developing specialist product knowledge and techniques

consistently providing sound information and advice to clients and relevant workplace personnel based on the consideration of time and cost and risk factors associated with possible corrective services

consistently applying specialist colour corrective services

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 andor the technical expert working in partnership with the assessor The technical expert may include the hairdresser andor an experienced person at the workplace

Competency should be demonstrated in the workplace or a simulated workplace environment in a range of situations that 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 manufacturers product safety data sheets

a salon or simulated salon environment

products and information from key product manufacturers colour ranges

clients with a variety of complex hair colour problems

Relationship to other units

This unit requires an assessment outcome that includes evidence of advanced technical knowledge of the chemical and physical effects of hair colour and lightening colour products on the hair In a workplace environment solving complex colour problems requires significant experience in colour and lightening services and the application of colour correction practices

The following assessment methods are suggested

Observation of the learner performing a range of tasks in an actual or simulated work environment over sufficient time to demonstrate hisher handling of a range of contingencies Tasks may include

the conduct of preservice analysis and consultation with clients and other operators

the development safe application and documentation of complex corrective colour case studies including colour deposit removal and prepigmenting techniques

Technical questions regarding peroxide levels and their applications in conjunction with complex colour correction safe product use and application methods

Thirdparty reports from experienced hairdressers
