Fifteen of the 19 schools proposed for closure and merger in Canterbury have had the proposed time line brought forward by Education Minister Hekia Parata and the Education Ministry.
The ministry said three of the schools proposed for closure had their date of closure brought forward but would pay teachers until the beginning of next year.
Five of them would effectively close at the end of this year under proposals, as they now have two options in front of them.
Ms Parata said the dates had been brought forward to minimise staff leaving the schools when they secure new jobs.
Parents and principals at the three intermediates - Branston, Linwood and Manning - say the minister assured them the schools would remain open until the end of next year.
They had been so certain of a guarantee they enrolled students this year and had advertisements outside the school saying they were taking students this year and next.
Ms Parata is today standing by her comments made in Parliament yesterday that she made no such promise, and was firm that any dates given to schools were proposals - not promises.
"I am really clear both in terms of my verbal communication and the letters that I have written that every element was a proposal.
"Clearly they were just proposals, because we've received submissions on them."
Principal at Branston Intermediate, Jennifer O'Leary, is fuming, saying her integrity had been compromised after assuring parents they would have a two year window to allow their children to complete intermediate education in one place.
Labour MP Megan Woods was cynical about the move, saying schools that were in National Party electorates had been saved, while Labour strongholds were seeing closures and mergers - some in areas unaffected by the earthquake.
Labour's acting education spokesman Chris Hipkins said five of seven schools originally proposed for closure or merger in National's electorates were saved, while eight of the 25 schools in Labour electorates had been saved.
Minister Parata took a paper to Cabinet two weeks before proposals were announced to schools bringing forward the dates for proposed closures and mergers.
She said it would bring more certainty for schools.
