Andrew Snowdon, the founder of the failing free school in West Sussex, blamed Ofsted and Education Secretary Michael Gove's department for the problems at Discovery New School.
He told Channel 4 News: "The real failing is one of an out-of-control Ofsted and a Department for Education that hasn't always sung from a single song sheet or provided adequate support at the right moments.
"We were trying to do something very different here and always looking for short-term measures and quick results doesn't always produce what you want."
A free school ordered to close by the Department of Education has said that it "echoed its concerns" regarding "inadequate" education being provided by the school in West Sussex.
The Discovery New School's chair of governors Chris Cook responded to Schools Minister Lord Nash's "grave concerns":
Since the monitoring inspection by Ofsted on 12 September the Governors of Discovery New School (“The Academy”) took the decision to suspend the Headteacher [...] pending an investigation as it is clear that trust and confidence may have been lost.
I would reflect that in the past eight weeks a real sea change in how the school perceives itself has taken place. I am pleased therefore to present to you a Further Action Statement which we believe properly addresses all the points raised by Ofsted.
There were "grave concerns" about education standards at a West Sussex free school, which has been ordered to shut in the first of such case in England.
Schools Minister Lord Nash said he was terminating the Discovery New School's funding agreement. In a letter to the school's chairman of governors Chris Cook, he wrote:
None of the school's teachers were delivering good lessons and all were still consistently inadequate or required improvement.
I recognise that my decision to terminate the funding agreement is likely to be disappointing for pupils, parents and all those involved with the school, but I will not allow a failing school to continue with no clear, workable plan to improve rapidly. It is not in the best interests of pupils to remain in an inadequate school.
The Department of Education is working with West Sussex County Council to ensure children affected by the closure of a free school will have suitable alternatives, a spokesman said today.
Discovery New School was one of the first 24 free schools - a flagship education policy of the coalition Government - to open in 2011.
Since the school was placed in special measures by Ofsted in May, we have monitored progress closely.
The trust has not provided evidence they are making the changes required. [Schools Minister] Lord Nash has today notified the trust that the department will terminate its funding agreement at the end of the spring term.
The Department for Education today said it had told the Discovery New School in West Sussex that it must close after expressing "grave concerns about the standards of education" it was offering.
Discovery New School in Crawley, West Sussex, has been told it must shut its doors on April 4 - the first time this kind of action has been taken.
In a letter to the school's chairman of governors, Chris Cook, Schools Minister Lord Nash said he was terminating its funding agreement. Discovery New School was declared failing and placed in special measures by watchdog Ofsted in May.
