A public consultation is to be held over plans for an extension at Rothwell Victoria Infants School.
Northamptonshire County Council is to display the plans at the school, in School Lane, from 3pm to 6pm on Thursday, October 22.
The proposal would see an extension at the front of the building, which would create a new classroom and staffroom.
An existing classroom would be converted to a library, with a small classroom also being extended.
The capacity of the school would also increase by eight pupils per year group.
If the application is successful, work would start on site in May 2016 and be completed by November 2016.
