Evidence Guide

EVIDENCE GUIDE
The evidence guide describes the underpinning knowledge and skills that must be demonstrated to prove competence. It is essential for assessment and must be read in conjunction with the performance criteria, the range statement and the assessment guidelines of the relevant Training Package.
Overview of assessment
A person who demonstrates competency in this unit of competency must be able to identify and describe the role of food, nutrients and other food substances in the body's performance and their application to trichological treatments. Knowledge and understanding of nutrition as it relates to trichological treatments must also be demonstrated. Knowledge of the relationship between nutrition and the body's systems as it relates to trichological treatments is also required.
Specific evidence requirements
Critical aspects for assessment and evidence required to demonstrate competency in this unit	knowledge and consistent application of relevant workplace policies and procedures
knowledge and consistent application of federal, state and local health and hygiene legislation and regulations
knowledge and consistent application of safe work practices and the safe use of products and electrical equipment, including the use of protective measures, according to manufacturer safety manuals and occupational health and safety legislation and regulations
knowledge and consistent application of the principles of nutrition as applied to trichological treatments
evaluating client needs and requirements and advising on nutritional needs, home care and complementary products
accurately and legibly recording relevant data.
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: relevant documentation, such as workplace policy and procedures manuals 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 one or more trichological consultations. Prerequisite units: none. Co-requisite units: WRHHS404A Perform trichological assessments WRHHS406A Develop and apply scalp treatment therapies.
Method of assessment	The following assessment methods are suggested. Observation of the learner performing a range of tasks in a simulated work environment, over sufficient time to demonstrate his/her handling of a range of contingencies. Tasks may include: identifying client characteristics and developing a nutritional treatment plan according to client needs providing advice according to client needs. Written and/or oral questioning to assess knowledge and understanding of nutrition in relation to the performance of trichological treatments, including after-care advice and relevant legislation. Completing workplace documentation relevant to the provision of trichological treatments. Third-party reports from experienced trichology professionals in the workplace. Completion of self-paced learning materials, including personal reflection and feedback from trainer, coach or supervisor.
Evidence required for demonstration of consistent performance	For valid and reliable assessment of this unit, evidence should be gathered through a range of methods to indicate consistent performance. It can be gathered from assessment of the unit of competency alone, through an integrated assessment activity or through a combination of both. Evidence should be gathered as part of the learning process.
Assessing employability skills	Employability skills are integral to effective performance in the workplace and are broadly consistent across industry sectors. How these skills are applied varies between occupations and qualifications due to the different work functions and contexts. Employability skills embedded in this unit should be assessed holistically in the context of the job role and with other relevant units that make up the skill set or qualification.
