The way NCEA achievement is measured at partnership schools has come under criticism by the Labour Party but a Whangarei charter school is refuting claims that its results are "massively overstated".
Chris Hipkins, Labour Party's education spokesman, said partnership school NCEA results were "massively overstated" after a Ministry of Education report to Education Minister Hekia Parata noted flaws with the way the NCEA achievement of school-leavers was being measured.
"It's disappointing that we're not getting apples for apples comparisons but it's even more disturbing that many kids are leaving these schools without the qualifications the Government says every child needs," Mr Hipkins said.
The report says the school leaver performance targets in charter school agreements for 2014 NCEA level 1 and 2 were set at 80.9 per cent and 66.9 per cent respectively.
But charter schools were using different methods than state schools to measure the achievement of school leavers.
