91351: Implement advanced procedures to process a specified product

Updated May 2015. This document has been updated in its entirety to address new issues that have arisen from moderation.


The specifications (including material specifications) for the product being made must be made clear. These need to be agreed prior to the product being made and may be teacher-given or developed in negotiation with the student.

The product

Any product that requires the combining and/or manipulation of materials could be the focus (it is often assumed that this standard belongs to the area of food). For example, glass, stringers and glass powder could be processed to make a glass panel (see the TKI assessment resources for this standard). Explanatory Note 9 gives examples of appropriate processing operations.

Advanced procedures

Students are to individually create a flow diagram depicting the sequencing of processing operations and testing that is needed. This flow chart should guide the implementation of advanced procedures to make a specified product.


Students should be making products that require advanced testing techniques to ensure established specifications are met. Explanatory Note 10 lists possible tests that reflect the rigour of what is expected for this standard.

Health and safety

This standard requires students to implement advanced procedures that comply with health and safety documentation. This documentation could include a relevant Hazard Analysis and Critical Control Points (HACCP) system or the Hazardous Substances and New Organisms Act (HSNO Act).

Confirming judgements

Assessors are required to make judgements about the ways in which procedures are implemented, as well as the quality of the finished product.

Students could provide evidence by establishing a schedule of tests and recording the outcomes, and taking and annotating photos.

Annotating an assessment schedule is one way for the assessor to confirm judgements around independence and accuracy (for Merit) and if the student has worked in a manner that economises time, effort and materials (Excellence). These annotations could be derived from classroom observation and/or discussions with students.
