Explanatory notes

1 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.

2 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.

3 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.

4 In this unit standard, all ranges identify the minimum that is critical for assessment. A wider scope may nevertheless be taught.

5 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.

Please note Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.

Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.

Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMRs). The CMR 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.
