# Mathematics and Statistics - annotated exemplars

An annotated exemplar is an extract of student evidence, with a commentary, to explain key aspects of the standard. It assists teachers to make assessment judgements at the grade boundaries.

Towards the end of 2018, NZQA arranged for specialists in the Mathematics and Statistics community to critique the Mathematics and Statistics clarification and exemplar documents published on the NZQA website.

This was to ensure all published documents were accurate and aligned with the achievement standards after concerns were raised in the sector. The April 2019 Newsletter provides a summary of changes for 91265, 91268 and 91587 made in response to the feedback from the subject specialists.
