The Government's decision to back down on plans to increase class sizes was driven by Education Minister Hekia Parata, Prime Minister John Key says.
"It was her decision but I was one of a small group of ministers that got on a conference call and went through our potential options," Mr Key told TVNZ's Breakfast programme today.
Mrs Parata initiated the conference call to address the backlash over the education policy announced as part of the Budget.
Mr Key was in Europe when Mrs Parata announced last week the Government would not go ahead with the policy.
He admitted today that communicating information about the policy to change student-teacher ratios and how the Government would mitigate the impact on the worst-affected schools had not been handled well.
