A decision is due to be made by the Royal Borough tonight on whether to approve its plans to move Oldfield Primary School to a new site in Bray Road.
The new school would cater for 420 children with an opening date of September next year.
Campaigners against the move argue the new site is not suitable because it is situated on greenbelt land and in a flood plain.
The meeting will take place at Maidenhead town hall in St Ives Road from 7pm.
