The Royal Borough has underlined its commitment to move Oldfield Primary School to a new site in Bray Road.
The Bray Action Group (BRAG) oppose the move because they believe the site is unsuitable as it is situated in both a flood plain and greenbelt land.
At a full borough council meeting on Tuesday questions were put to the council by BRAG members calling for a reconsideration of the plans.
Responding to the questions at the Windsor Guildhall meeting, Cllr Phil Bicknell, cabinet member for children's services said the move was propelled by a demand for school places and they would not be looking to push the application back.
"The number of children needing spaces in the borough is imperative," he said.
"The whole community across the borough should be making sure we are doing everything possible to get the best outcome for our children."
The new school would cater for 420 children and aims to open in September next year.
A decision on the application is due to be made in September.
