Application
The unit of competency covers the skills and knowledge required to construct blocks to meet size and fit specifications in garment production. Blocks are used as the basis for patternmaking to develop new styles.
Work may be conducted in small to large scale enterprises and may involve individual and team activities.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
