Ms Tolley has put an end to speculation over whether Grammar's decision to have the majority of its Year 11 students sit Cambridge International Exams instead of NCEA is legal.
Questions were raised this week over whether Grammar was breaching the Education Act which says schools must offer a "nationally and internationally recognised qualifications system", such as NCEA.
The ministry has said the Cambridge exams do not meet that requirement as they are not nationally recognised.
But Ms Tolley disagrees, saying they are accepted by all universities.
She says that the Auckland school is offering NCEA to those who want it, even though it will be only a handful of Year 11 students.
Yes Minister, well done.
You've just earned National a couple more points in the next Roy Morgan poll. Why even the Hammeroids might have to admit Labour could never in a million years allowed such a terrible intrusion on state control.
This is the minister who has been falsely painted by Labour and its media friends as weak. Doesn't look particularly weak to me!
Lets have more of the same common sense please.
