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 consult with clients and perform physical and visual examination of hair and scalp, and microscopic analysis of hair, in order to accurately identify hair and scalp conditions. She/he must be able to develop appropriate responses to identified problems and plan a relevant treatment program as required. Knowledge of the causes and appearance of a broad range of disorders of the hair and scalp and their treatment must be demonstrated. |

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 |
demonstrated consistent application of patient consultation according to workplace procedures |
| consistent application of patient assessments based on examination and/or microscopic analysis |
| consistently accurate, relevant and well-organised recorded patient information that can be readily interpreted by other professionals |
| consistent, sensitive and clear communication of patient diagnosis and options that takes into account any cultural or physical requirements. |
| |
| |
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 an experienced person at the workplace. Competency should be demonstrated in the workplace or 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 occupational health and safety legislation and regulations client history systems a range of patients with different requirements a range of equipment suitable to the provision of trichological consultations 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 skin and hair science and nutrition in the performance of trichological treatments. : none. : WRHHS403A Apply knowledge of hair and scalp problems to trichological consultations WRHHS405A Apply the principles of nutrition WRHHS406A Develop and apply scalp treatment therapies. |
| |
Method of assessment | The following assessment method is suggested. Observation of the learner performing a range of tasks in an actual or simulated work environment, over sufficient time to demonstrate his or her handling of a range of contingencies. Tasks may include: consultation with patients recording client details and history physical and visual examination of hair and scalp diagnosis based on information gathered, including observations and analysis communicating diagnosis and negotiating options with patients. |
| |
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. |
