National is desperate that their charters chools are successful. So naturally, they allowed them to lie about how good their results were:
Charter school pass rates are out of line with state schools, a report has revealed.
[...]
The reported results were inflated because the charter schools, also known as partnership schools, were using a different method from state schools to report NCEA pass rates.
The report showed Vanguard Military School on Auckland's North Shore and Te Kura Hourua O Whangarei Terenga Paraoa reported they had met their 2014 NCEA leaver targets - but when the figures were analysed, they did not.
Vanguard reported a 100 per cent pass rate for NCEA Level 2. However, when revised in line with NCEA standards it dropped to just 60 per cent. It met Level 1 standards.
At Te Kura Hourua, neither Level 1 or Level 2 NCEA standards were met once revised: Level 1 dropped from 82 per cent to 77.8 per cent, and Level 2 dropped from 80 per cent to 55.6 per cent.
This sort of chicken-strapping is normal for National - see also their lowball targets for private prisons. But it deliberately sets out to mislead the public, and potentially persuades parents to send their kids to a substandard school as a result. That's obviously great for National's charter school cronies, who get to profit as a direct result of these lies. But its very, very bad for the public. But then, when has National ever cared about us?
