The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the following is essential:
applying the principles of cosmetic chemistry in beauty therapy treatments, including:
chemical concepts for cosmetic products and skin treatments
range of organic chemistry applicable to cosmetic chemistry
percutaneous absorption
chemical formulation of range of cosmetic emulsions in relation to their function on skin
formulation and functions of basic compositions of facial masks and make-up
formulation, function and action of cosmetic ingredients on skin
formulation and function of facial peels and exfoliants
provision of post-treatment care and advice
applying a range of beauty therapy treatments, using a variety of techniques and procedures involving cosmetic products
accurately and legibly recording relevant data.
Context of and specific resources for assessment
Assessment must ensure:
that competency is consistently demonstrated over a period of time and observed by the assessor or the technical expert working in partnership with the assessor as described in the Assessment Guidelines
that competency is demonstrated in the workplace or a simulated workplace environment in a range of real work situations which may include client interruptions and involvement in other related activities normally expected in the workplace.
Assessment must ensure access to:
text and online resources
treatment products from a professional range
relevant workplace documentation including:
manufacturer's equipment instructions
product instructions
manufacturer safety data sheets
workplace policies and procedures manuals
a range of clients with different beauty treatment requirements.
For further guidance on the use of an appropriate simulated environment, refer to the Assessment Guidelines in this Training Package.
Methods of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
observation of learners performing a range of tasks in the workplace or a simulated work environment, over sufficient time to demonstrate handling of a range of contingencies, including:
identifying the concepts of cosmetic chemistry and developing and maintaining safe work practices
relating principles of cosmetic chemistry to a variety of treatment processes, according to client and safety requirements
written and oral questioning appropriate to the language and literacy level of the learner, to assess knowledge and understanding of the application of cosmetic chemistry to the performance of beauty therapy treatments, including after-care advice and relevant legislation
completion of workplace documentation relevant to beauty therapy treatments
third-party reports from technical experts.
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
SIBBBOS402A Provide body treatments
SIBBCCS301A Apply the principles of skin biology to beauty treatments
SIBBCCS404A Work in a skin therapies framework
SIBBCCS405A Develop treatment plans
SIBBFAS405A Provide advanced facial treatments.
