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.

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.

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.
