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 trichologist and/or a nutrition specialist and may be in a simulated environment.

Competency should be demonstrated in 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:

an appropriately stocked and equipped clinic or simulated clinic environment

relevant documentation, such as:

workplace policy and procedures manuals

occupational health and safety legislation and regulations

relevant learning materials

a qualified workplace assessor or assessment team.

Relationship to other units

This unit is a co-requisite for a range of trichology units. It requires an assessment outcome that includes evidence of the application of knowledge of nutrition to the performance of trichological treatments.
