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 consistently perform pre-service hair analysis, consult with clients regarding the desired curl/body result, and then perform the full chemical straightening and relaxing service to achieve that outcome to the satisfaction of the client. Client and operator safety must be ensured at all stages during the chemical straightening and relaxing process. Knowledge and skill in the application of relevant legislation and workplace policies and procedures must also be demonstrated. |

Specific evidence requirements |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | consistently conducting accurate pre-service hair and scalp analysis |
consistently selecting products, equipment and techniques appropriate to desired outcomes and predetermined designs |
| consistently applying straightening products and techniques without hair breakage |
| consistently and successfully assessing the development of degree of curl/wave relaxing |
| consistently performing the full rinse and neutralising service according to manufacturer's instructions and/or workplace procedures |
| consistently applying safe work practices and manufacturer's instructions. |
| |
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 hairdresser 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, including occupational health and safety legislation and regulations, workplace policy and procedures manuals and manufacturer's product safety data sheets a range of hair straightening products and equipment a variety of clients presenting with a range of hair types and chemical hair straightening or relaxing requirements a hairdressing salon or simulated salon area. |
| |
Relationship to other units | This unit requires an assessment outcome that includes evidence of well-developed client communication skills, knowledge of the chemical and physical effects of chemical straightening and relaxing products on the hair, and the ability to apply safe working practices during chemical services. : WRHCS201A Prepare clients for salon services WRHCS205A Follow personal health and safety routines at work SIRXOHS001A Apply safe working practices. : WRHHS301A Apply the principles of hairdressing science WRHWP302A Operate effectively as a hairdresser in a salon work team. |

Method of assessment | The following assessment methods are suggested. Observation of the learner performing a range of tasks in an actual or simulated work environment, over sufficient time to demonstrate his/her handling of a range of contingencies. Tasks may include: conducting pre-service analysis predetermining with client the finished degree of straightening and relaxing selecting products and equipment completing a number of full services to achieve a predetermined straightening result recommending after service products and hair care routines to clients. Written questions on the physical and chemical effects of chemical straightening and relaxing products on the hair's structure. |
| |
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. |
