Suffolk County Council wants a two-tier education system
Plans to close four more middle schools in Suffolk have been given final approval by the county council.
Middle schools in the Sudbury and Great Cornard area will close and primary and secondary schools there will take on two additional year groups.
Some school buildings will be extended to accommodate the additional year groups and some primary schools will move to former middle school premises.
The changes, costing £8.1m, are scheduled for September 2013.
County councillor Graham Newman, who is responsible for children, schools and young people's services, said: "The cabinet believe these changes will help young people in the area to have an improved standard of education."
Mr Newman said there may be a possibility of a new so-called "free school" for 11 to 16 year-olds on the site of Stoke by Nayland Middle School.
Altogether 40 middle schools will be lost as Suffolk moves from a three-tier to a two-tier educational system.
Schools in Lowestoft and Haverhill will make the change in 2011.
The final area to undergo the transfer will be Bury St Edmunds in 2016-17.
The council said it had allowed for significant government funding cuts over the coming three or four years and believed it would still be able to budget for the multi-million pound changes.
