Ms Parata says the backdown was in response to parents' concerns about the proposed changes.
The Government had mistakenly believed the changes were modest and would be accepted.
They were wrong, and have admitted they were.
Earlier this week, Patrick Walsh - Secondary Principals' Association of New Zealand president - had said he was flabbergasted the Government had ever thought increasing class sizes was a good idea.
Thankfully, common sense has prevailed. National will lick its wounds over this one and ponder the way forward as it considers other ways to save the $40 million plus within the education sector.
Looking back, one can now see why the no-nonsense Anne Tolley (now the police minister) was not left with the education portfolio at the last election. Perhaps the National leaders thought Ms Parata - viewed as consultative and caring - could slip the class reductions through.
They were wrong.
Despite personality changes, a bad idea is still a bad idea.
And education remains National's problem child.
