The Herald reports on the achievement rates gender gap:
The achievement gap between boys and girls is widening. Last year, half of female students at secondary schools passed NCEA Level 3 or gained sufficient attainment to attend university, while 37.1 per cent of male pupils passed.
The growing failure of boys in the education system is a scandal. If it was girls, there would be demands for the UN to investigate this discrimination, commissions of inquiry etc etc.
No doubt there are many factors at play, but one stat I recall is that there has been no new single sex boys schools built in 30+ years.
