Definition
Worksite documentation refers to instructions to staff on policy and procedures
(including the application of legislation to worksite situations), which are formally
documented, and are available for reference at the worksite. Examples are standard
operating procedures, specifications, manuals, and manufacturer's information. For
people already employed in the industry, the worksite referred to is their employer's.
For other people, the worksite will be either a local worksite or a typical New Zealand
worksite. For these learners, the Industry Training Organisation will ensure that the
training given by accredited providers meets these standards.

Please note
Providers must be accredited by the Qualifications Authority, 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 the Qualifications Authority 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.
