Families living at Priors Hall Park in Corby are angry the opening of its new primary school and community centre will be delayed.
In June, Corby Council approved a planning application for the school and building work was expected to start this summer with an opening date of September 2015.
The school, to be built by developer Bela, is now unlikely to open before 2016.
A Priors Hall Park Neighbourhood Association spokesman said: “For the past 18 months we have been under the impression from both the developer and the county council that a school would open in September 2015.
“We have worked with Bela to this end and have been communicating with residents who have been planning school arrangements for their children.
“We are also concerned about the community centre which has been planned to occupy the same building as the school.”
Priors Hall resident Darren Ward said: “We moved to Priors Hall more than three years ago and were confident a primary school would be built in time for our son to go to school on site.
“We will now have to drive our son to the school in Weldon each day. We are also still waiting for play facilities here at Priors Hall Park.”
The £6m primary school will eventually accommodate 420 children.
A Bela spokesman said: “In consultation with Northamptonshire County Council, the local authority responsible for education, concerns were raised that there were lower than expected numbers of children at Priors Hall Park.
“As a result it was decided that the opening of the school in September 2015 could not be justified given the already existent surplus in capacity of schools within the area.
“The primary school is now planned for opening in September 2016 and by agreement with local the authority there may be a possibility of an earlier opening at the beginning of 2016 or after Easter that year.”
A spokesman for Corby Council said: “We are disappointed that building of the combined community centre and primary school has been delayed.
“The council acknowledges residents concerns and will do whatever it can to help get things moving, although it is now unlikely that the original timeframe for opening in September 2015 will be met.
“The council will be meeting Bela in order for them to explain how they now intend to progress.”
