Plans for the first free school in Cornwall have been approved by the government.
St Michael's Catholic Secondary in Truro, which currently has 30 pupils, is aiming to open in refurbished buildings in 2012.
Head teacher Neil Anderson welcomed the decision saying he was "over the moon".
Free school critics claim they can be socially divisive, but governor Joyce Sanderson pledged that St Michael's would be "open to everyone".
Approval from the Department of Education is subject to acceptance of the school's business plan.
Speaking to BBC Spotlight, Mr Anderson said he was "overwhelmed with emotion".
Ms Sanderson said: "We will not be selective, we will admit if we are over-subscribed, only 50% of Catholic children and it's open to everybody."
The school is hoping to open in Camborne in September next year.
