Special notes

This unit standard recognises knowledge of woven fabrics, it builds on the knowledge covered by Unit 19841, Demonstrateelementaryknowledge of the operations, processes and products of textile manufacturing.

Elements and performance criteria

Element 1

Demonstrate knowledge of fabric structure and weaving terms.

5.3Fabrics are described in terms of appearance, fabric properties and end-use.

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.
