What to include in your analysis of variance

An analysis of variance is a statement in which your board provides an evaluation of progress you’ve made in achieving the aims and targets set out in your charter.

It shows parents, whānau and your community the actions you've taken to achieve your aims and targets. It shows how successful these actions have been towards improving student achievement. 

The analysis of variance should also provide the basis for plans for the coming year. 

The legislative requirements for what an analysis of variance must contain are set out in Section 87(2)(e) of the Education Act 1989 — NZ Legislation website(external link) ¹.

Develop your analysis of variance

The following template can be used to report on the progress your school has made in achieving the targets set in your charter.

It allows you to comment on:

  • the actions you’ve taken
  • the outcomes of these actions
  • the reason for the variance between the targets you set and what was achieved
  • an evaluation of the actions taken and their results, and
  • your planning for next year.

The use of this template is optional. It is available in English and te Reo.
