The school said its action was in response to parents' concerns
A Kent school that sent home 61 pupils in a single day in a drive to improve standards has been placed in special measures by Ofsted.
The governing body at Wilmington Enterprise College, in Dartford, has resigned in response to the decision.
Kent County Council said they would offer extra help and implement a new management structure for two years.
Last month the school cracked down on bad behaviour in response to concerns raised by parents to Ofsted inspectors.
Forty-six students were excluded for the day for disruptive behaviour and 15 pupils were sent home for not wearing the correct uniform.
A council spokesperson said the school would partner with Dartford Grammar School for Girls under the leadership of its head teacher Jane Wheatley.
Belinda Langley-Bliss, acting head teacher at Wilmington Enterprise College, is to become head of college with responsibilities for the day-to-day running of the school.
Simon Webb, Kent County Council's area children's services officer for Dartford and Gravesham, will take on the responsibilities of the governing body.
Mrs Langley-Bliss said:"The support that comes with special measures is designed to make sure Wilmington Enterprise College makes rapid and sustainable improvement.
"There will be a comprehensive review of teaching and learning and the curriculum offered to all students."
Wilmington Enterprise College is one of the 470 schools in the Government's National Challenge programme for under-performing schools.
Last year, just 28% of students achieved at least five grade C passes including maths and English.
