Please note Providers must be granted consent to assess against standards (accredited) by NZQA, 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. Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing NZQA National Qualifications Services SSB Code 130301 New Zealand Qualifications Authority 2016 NZQA registered unit standard 8450 version 5 Page 3 of 3 to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
