Please note


Providers must be accredited by NZQA, or an inter
-
institutional body with delegated
authority f
or 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.


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.
