Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the following is essential:
knowledge of skin science and skin disorders as they apply to trichological treatments
applying a variety of trichological treatments, using a variety of techniques and procedures involving scalp and hair care
provision of after-care service and advice.
Context of and specific resources for assessment
Assessment must ensure access to:
a salon or a simulated salon environment that includes a range of work situations such as client interruptions and involvement in other related activities normally expected in the salon
a fully equipped workstation which includes as minimum:
an adjustable client chair
clean client gown or wrap
a plentiful supply of clean towels
relevant documentation, such as:
relevant health regulations
salon procedures
product information
a range of clients with different hair and scalp conditions
a professional hair and scalp trichological treatments products range.
For further guidance on the use of an appropriate simulated environment, refer to the Assessment Guidelines in this Training Package.
Method of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
direct observation of the learner performing trichological consultations and treatments.
written or verbal questions appropriate to the language and literacy level of the learner to test knowledge which may include:
principles of skin science and skin disorders as they relate to trichological treatments
knowledge of skin science and skin disorders in relation to trichological treatments and procedures, including:
main functions and role of the skin, such as:growth, development, ageing and healing of human skin, inheritance of physical traits, function, formation and behaviour of the major skin chemicals, role of endocrine glands and hormones in the body, skin disorders, provision of after-care service and advice, role and limitations of trichology in the management of a range of skin disorders
review of portfolios of evidence and third-party reports of on-the-job performance.
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:
