Definitions
Intermediate light fabrication trade practice – trade knowledge and practical skills
expected by industry of a typical second or third year light fabrication apprentice.
This includes the ability to produce basic objects as defined by the range in element
3.
Industry practice – safe and sound practices generally accepted by competent trade
persons within the fabrication industry.
Job specifications – instructions relevant to the safe completion of the specific task,
such as technical specifications, assembly instructions, drawings, parts lists, standards,
codes of practice, test and commissioning procedures, and verbal instructions.
Safety guidelines – guidelines for the safe operation of machinery and tools, such as
those listed in the references, as well as guidelines for specific machines in workshops.
Worksite procedures – operational procedures put in place by the candidate’s
employer. These include site safety procedures, equipment operating procedures,
job procedures, quality assurance, and procedures for the handling and disposal of
materials and waste.

Please note
Providers must be accredited by NZQA, 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 NZQA 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.
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 organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
