The formal application to open a new primary school in Hemel Hempstead has been submitted to education chiefs.
West Herts Community Free Schools Trust wants to open the school in 2014 on the site of Jupiter Drive Primary, which closed in 2007 due to falling pupil numbers.
But now the town is running out of space for little ones and Herts County Council, which was behind the school closure five years ago, is supporting the latest proposal.
The new school would take in two forms at reception level and more pupils would be accepted as that first year group progresses up the school, becoming full in 2020.
Highfield’s Jupiter Drive Primary was one of three schools to be closed in Hemel Hempstead but since then millions have been spent expanding other schools to meet a rising demand. The Department for Education is expected to make a decision next summer.
