contraindications to particular 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 trichologist and may be in a simulated environment

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 such as workplace policy and procedures manuals

a range of clients with different requirements

a range of equipment and products appropriate to the hairdressingtrichology workplace

product labels charts and sources of product information

a qualified workplace assessor or assessment team
