Oxford's only remaining state girls' school looks like being moved into a caretaker's house and three mobile classrooms.

Staff and pupils at Milham Ford School, Marston, believed that they would be moving into new purpose-built buildings next year on Oxford School's site, in east Oxford.

But headteacher Anne Peterson said her school had been badly let down by Oxfordshire County Council.

She said: "The school has been given short shrift. We are not happy, especially for our children who are leaving one of the best learning environments in the city.

"We are going one year early, with the sale of the school site providing the finance for much of the reorganisation. Now we learn there are to be no new buildings. We are being offered a refurbished three bedroom caretaker's house and three mobile classrooms on a parking lot."

The sale of the current school and land is expected to pay for at least a third of the £30m bill for the city schools reorganisation.

Under the reorganisation plans, Milham Ford's 150 staff and pupils are expected to move to Oxford School's Glanville Road site.

Mrs Peterson believed they would be moving into spacious new accommodation and would share part of a new £4.5m building, containing 21 classrooms. A plan to move the 100-year-old school to Donnington Middle School was also considered.

Mrs Peterson said: "Our teachers are being redeployed, our pupils are leaving a wonderful school site and we would be taking more than 30 top A-level students to the Oxford School. In return we are being offered nothing.

Tom Long, of Oxfordshire County Council, said: "No decisions have been made whatsoever.

"We are looking at all possibilities. It may involve the refurbishment of premises at Oxford School, use of part of Milham Ford or another property. Oxford School is an expanding school and is bending over backwards to support Milham."
