Overview of assessment |
A person who demonstrates competency in this unit of competency must be able to identify and describe the application and role of nutrients and other food substances in trichological treatments. Knowledge and understanding of nutrition as it relates to trichological treatments must be demonstrated. Knowledge of the relationship between nutrition and the body's systems as they relate 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 the principles of nutrition as applied to a range of trichological treatments |
| demonstrated ability to design and implement dietary modifications in a manner acceptable to the client/patient |
| demonstrated ability to advise on nutritional supplements and determine the most appropriate supplementation |
| evaluating client needs and requirements and advising on nutritional needs, home care and complementary products |
| referring clients to other professionals where indicated |
| 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: an appropriately stocked and equipped clinic or simulated clinic environment relevant documentation, such as: workplace policy and procedures manuals occupational health and safety legislation and regulations 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 trichological treatments. : none. : WRHHS405A Apply the principles of nutrition WRHHS407A Perform hair loss diagnosis WRHHS409A Design and apply hair loss 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 therapy plan according to an assessment of client needs providing nutritional therapy providing complementary advice according to client needs. Written and/or oral questioning to assess knowledge and understanding of the relationship between nutrition and healthy hair and scalp. Case studies and scenarios. Third-party reports from experienced trichologists in the workplace. Completion of self-paced learning materials, including personal reflection and feedback from the 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. |
