Special notes 1 Enterprise requirements, for the purposes of this unit standard, refers to any policies, procedures, and requirements of the company and/or workplace involved, and any ethical codes of relevant professional management, which collectively provide a standard that applies to all competent performances in this unit standard. It is assumed that such enterprise requirements exist in all companies and/or workplaces. New Zealand Qualifications Authority 2016 19597 version 2 Page 2 of 4 2 As the content of this unit standard is largely informational, performance criteria assume that knowledge will be acquired from reference texts, models, and other information-bearing media. No one textbook or other source of information is envisaged, as new approaches to the study of anatomy and physiology are published regularly. 3 All demonstrations of knowledge for assessment in this unit standard must be evidenced with relation to the application to and use in the beauty services industry. 4 For the purposes of this unit standard, explain and explanation are to be interpreted to include any form of visual and/or other aid, such as diagram, gesture, or model, that is used in addition to or in place of a verbal explanation. 5 In this unit standard, all ranges identify the minimum that is critical for assessment. A wider scope may nevertheless be taught. 6 The focus of this unit standard is the anatomy and physiology of human systems that are healthy and functioning properly. Diseases and disorders are included only where appropriate to the professional competence of a beauty practitioner. Elements and performance criteria Element 1 Explain the anatomy of hair and hair growth. Performance criteria 1.1 Explanation describes the types of hair anatomy. Range lanugo, vellus, terminal. 1.2 Explanation describes the anatomy and physiology of the follicle and hair in terms of inner root sheath, outer root sheath, connective tissue sheath, vitreous membrane, medulla, cortex, and cuticle. 1.3 Explanation describes the stages of follicle development and hair growth in terms of anagen, catagen, and telogen. 1.4 Explanation describes the causes of hair growth in terms of systemic (normal, abnormal), congenital (normal, abnormal), and topical. New Zealand Qualifications Authority 2016 19597 version 2 Page 3 of 4 Element 2 Explain skin conditions, and the effect of electrical currents on skin. Performance criteria 2.1 The common skin diseases and disorders are identified, noted and discussed for referral. Range 2.2 abnormalities, post-treatment disorders; bacterial, fungal, viral, parasitic, systemic, traumatic. Explanation describes the effects of galvanic, high-frequency and blend currents on the pilosebaceous unit. Element 3 Explain electrical and chemical processes in electrical epilation. Range galvanic, high frequency, blend currents. Performance criteria 3.1 Explanation describes the influences of the electrical components that affect how a galvanic and high frequency current is produced. 3.2 Explanation describes atoms, elements, molecules, compound, ions, and electrodes involved in electrical epilation treatments. 3.3 Explanation describes the chemical and physical effects of electrodes involved in electrical epilation treatments. 3.4 Explanation and demonstration illustrate the safety precautions involved in electrical epilation procedures. 3.5 Explanation describes the behaviour and characteristics of electrical currents used in electrical epilation treatments. Please note Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment. Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards. Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards. New Zealand Qualifications Authority 2016 19597 version 2 Page 4 of 4 Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
