Clarification details
November 2015.
The purpose of clarifications
We create clarification documents to help people understand the current requirements of achievement standards. Clarifications do not introduce new criteria, change the intent of the standard, or change what we expect from assessment.
These documents unpack and explain the language and intent of the standard so people interpret and apply the standard consistently. We provide examples or guidance as illustrations only. They are not prescriptions or requirements.
For official requirements, always refer to the current version of the achievement standard as published by NZQA.
Pattern Drafting
Pattern drafting requires a pattern block and/or working drawing to be established by using key measurements and using these to develop a pattern which interprets a garment’s design including its special features. Line accuracy is a key quality of pattern drafting. Patterns are tested using toiles and mock-ups to check the fit of the garment, to ensure that pattern pieces correctly interpret a design and its special features, and to make any adjustments.
The pattern drafting process…block > pattern
A possible process a student could follow when drafting a pattern could be:
- Produce a block – no seam allowances
- Draw design lines on the block
- Trace off design
- Add seam allowances
- Trialling/toile
- Adjustments to block
- Trace of final pattern
- Label with pattern markings and notches
A pattern block does not have seam allowances; a pattern has seam allowances.
Special features
In this standard students are expected to create a pattern which includes special features. These may include: panel or princess seams, an empire line, disposal of fullness, pleats, gores, yokes or button wraps, and dart manipulation.
Student evidence
Student evidence could include:
- knowing how to draft a pattern block from measurements and how to calculate these
- knowing how to interpret pattern adaptation instructions such as those found in a pattern making text
- creating a pattern guide sheet
- being able to label the pattern with the correct symbols, notches, seam allowances and information to enable the construction of the garment.
