Our education system is our antidote to unequal wealth. We expect our tax-funded schools to iron out the disadvantages of children from low-income households and give every child a chance to leave school well equipped for life and earn a good living.
For most of our poorest children, the system
succeeds, but for nearly a quarter of those in low-decile schools, it does not. They leave with no qualifications. They are the "long tail" on charts of the population's educational achievements.
Policy-makers have agonised over the long tail for 25 years or more, and improvement has been minimal. The gap between low and high-decile schools' pass rates at NCEA level 2 has reduced from 30 per cent to 25 since 2009. The gap remains 30 per cent at level 3. Just 17 per cent of those in low-decile schools received University Entrance, compared with 60 per cent from the high deciles.
The long tail persists despite more than 80 policy initiatives aimed at these pupils since the millennium. Current Education Minister Hekia Parata says she takes heart from research that suggests only 18 per cent of the differences in student achievement are socio-economic.
She quotes an OECD study that found differences mainly result from quality of teaching, pupils' expectations, school leadership and the relationship between parents and teachers.
