About this dataset
The Ministry of Education carries out statistical collections (roll returns) from New Zealand schools at different times during the year.
The data reported here is based on the 1 July roll returns since it provides detailed information on age and ethnicity for trend analysis.
Purpose of collection
The Ministry uses the collected data in a number of ways: to fund and staff schools; to support policy analysis, development and decision making; to monitor the outcomes of the New Zealand education system; and for national and international reporting purposes.
