SEAFORD Head Community College's new interim headteacher Fiona Wright will begin at the school on June 6.
Ms Wright is currently head at Peacehaven Community School.
The announcement comes just a week after Seaford Head was rocked by news of headteacher Martin Clark's departure after just five months in the job.
He was the fourth headteacher to work at the school since Robin Precey left in February 2004, following a disastrous Ofsted report which resulted in the school being put in special measures.
East Sussex County Council's children's services director Denise Stokoe said: 'We are delighted that Fiona Wright has agreed to take up the post of executive principal of Seaford Head Community College until a permanent appointment is made.
'Fiona is a very experienced and successful headteacher. Prior to taking up her post at Peacehaven she was the headteacher of Eastbourne Technology College. Her present school has just received an outstanding Ofsted inspection report.'
Seaford Head chairman of governors Roger Case said: 'I am thrilled that such an experienced and talented professional is going to lead Seaford Head at this crucial time. I am confident Fiona Wright will continue to build on the progress made and that she will work well with our senior leadership team and all the staff.'
It is not clear how long Ms Wright will stay at Seaford Head. A council spokesman said she would stay until a permanent head was found. He could not give any indication how long this would be.
Meanwhile, Peacehaven Community School will be run by deputy head Andrew Wright
Ms Wright has been the school's head since it opened in September 2001.
