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 prerequisite to another—they are related skills.
Holistic assessment with other units relevant to the industry sector, salon and job role is recommended, for example:
SIHHCCS302A Perform a full client consultation
SIHHOHS201A Apply salon safety procedures
