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 providers wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
This unit standard is covered by AMAP 0030 which can be accessed at
