Please note

Providers must be accredited by NZQA, or an inter-institutional body with delegatedauthority for quality assurance, before they can report credits from assessment againstunit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be accredited by NZQA before they can registercredits from assessment against unit standards.

Accredited providers and Industry Training Organisations assessing against unit standardsmust engage with the moderation system that applies to those standards.

Accreditation requirements and an outline of the moderation system that applies to thisstandard are outlined in the Accreditation and Moderation Action Plan (AMAP). The

AMAP also includes useful information about special requirements for organisationswishing to develop education and training programmes, such as minimum qualifications fortutors and assessors, and special resource requirements.
