A march is taking place in Thrapston on Saturday, March 29, in protest about plans to switch education in the town from a three-tier to a two-tier system.
A group of parents opposing the decision, which would see the King John School closed, have organised the march, which will start at the under-threat school in Market Road at 11am.
Northamptonshire County Council is currently consulting parents on the switch from three to two-tier.
Parent Suzanne Woods said: “Consultation meetings have taken place, though many important questions have yet to be satisfactorily answered by the county council.
“Thrapston is rapidly expanding, with 600 new homes planned forecast population to expand by 25 per cent between 2010 and 2020, making proposals to close school appear short-sighted and not aligned with Thrapston Town Council plans for the community.”
Northamptonshire County Council began its consultation on January 10, and a decision will be made on April 15.
In response, Suzanne said parents established a Save King John support group with a remit to question the proposed change and encourage proper debate.
She added: “A three-tiered education system has operated successfully in the region for many years and could continue to do so.”
Speaking when the consultation was announced, county councillor Catherine Boardman, cabinet member for children, families and education, said: ““As things stand, we believe that the three tier system does not represent the best long term approach to education in the area.
“We know that a number of schools in the area are underperforming and that has a knock-on effect on parental preferences for where their children are educated. As a result, we’re seeing falling pupil numbers in some of the schools.”
