A comparison of new and old deciles is not useful until the funding numbers are taken into account.

A Herald data analysis shows how much funding has changed for each school in the country.

This analysis reveals that the schools from decile one to four could see massive funding changes, even if the ratings for the schools haven't changed.

This renders the simple decile to decile comparison meaningless, particularly for lower deciles - where most of the funding is directed.

For example, the decile four Mt Roskill Grammar in Auckland has seen its funding increase by over $67K - despite no change in its decile rating.

Similarly, Frankton School in Hamilton saw its funding decrease by over $37K while its rating remained at decile 3.

A data table published below allows readers to explore all the 312 schools for which decile rating hasn't changed but these schools have had a 'step change', according to the Ministry of Education classification.
