The Evidence is in Two: Data for the School Leavers of Every High-School in NZ

The WORST schools in each decile!

I have spent the last month acquiring and processing significant data on the leavers of every high school in New Zealand – with great help from the good people at Education Counts. This is far more important than the cohort data (by Year level) that comes out in February.


Last week on Kiwiblog I highlighted the top school in each decile in NZ. Many of these are breaking the link we are told exists that means that schools just can’t succeed with some kids. This week I am contrasting them to the bottom school in each Decile.


I have chosen not to name the bottom schools – not for the adults involved but through consideration for the attending children.

The comparison for schools in each decile is by University Entrance achievement (schools with 75 or more students) and retention.

All measure are for LEAVERS across year levels.

UE at 96.6% for leavers. Leaving before 17yo – 2.7%.

These gaps are astonishing and inexcusable. They cause incalculable harm.
The key systemic takeaways:

  • Socio-economics is not determinant of school outcomes – we need to bury that excuse.
  • Ethnicity is not determinant of school outcomes – we need to bury that excuse also.
    It is about clear vision and aspiration, quality leadership (including engaging parents), quality teachers, a world class programming.
    NZ cannot afford this pattern to continue and to be frank, Hipkins and Ministry have shown no interest in changing things – let alone the Teachers Council and Unions. They do not care for the children – they are about mediocrity, power and control.
Until this is transformed there will be minimal intergenerational wealth change. On average someone with a degree earns $1.3m more over a learning lifetime. There are, of course, exceptions.

The information is of high value educationally and has taken a considerable amount of time and expertise. I can make it available for use within a school (under copyright) or professional organisation at a relatively small price.
