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
