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 pre-requisite to another— they are related skills.

Holistic assessment with other units relevant to the industry sector, salon and job role is recommended, for example:

  • SIHHCLS304A Neutralise unwanted hair colour tones
  • SIHHOHS201A Apply salon safety procedures
