Definitions
Samples may include but are not limited to – prepared materials and test materials
such as standards and reagents.
Organisational requirements refer to instructions to staff on policy and procedures
which are formally documented or generally accepted at the worksite. This may
include legislation; industry standards and methods; national and international
standards and methods; customer/organisation developed methods; standard
operating procedures; specifications; manuals; and manufacturer’s information.
Perform refers to completing the individual components of the test sequentially in
terms of the relevant test method and organisational requirements. Components will
vary between tests and include but are not limited to – the completion of tasks, from
sample and equipment preparation to the calculation and reporting of results.
Perform does not include the evaluation or the troubleshooting of tests.

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 granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Consent 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.
