Schools in New Zealand by decile

As at July 2018, number of schools


Students from low socio-economic communities face more barriers to learning than students from high socio-economic communities. Schools that draw their roll from these low socio-economic communities are given greater funding to combat these barriers. The mechanism used to calculate and allocate this additional funding is most often known as school deciles.

Schools are assigned a socio-economic score based on five census derived socio-economic factors. The 10 percent of schools with the lowest scores are considered decile 1 schools, the next 10 percent of schools are considered decile 2 schools, etc. Decile 1 schools have the highest proportion of low SES students.
