Dean Academy in Lydney placed in special measures
A school in the Forest of Dean has been placed in special measures after being rated inadequate.
Leadership, management and quality of teaching were criticised at the Dean Academy in Lydney, following an Ofsted inspection last month.
The report found too few pupils achieved five good GCSE results, and disabled and disadvantaged pupils made poor progress.
The school said it was "committed to raising standards".
The Ofsted report also found pupils' personal development, behaviour and welfare required improvement, and attendance levels were too low.
In a letter sent to parents, acting head teacher John Barrett, and Tim Gilson, chief executive officer of the Athelstan Trust, which runs the school, said they were "committed to addressing the issues raised in the report".
They said staff had "already taken many actions that are making a difference".
The academy's head teacher stepped down earlier this month, having been absent from work since September .
A new sponsor was appointed for the academy earlier this year after it lost its previous one in 2014.
A meeting will be held on 1 December for parents to discuss the report with staff.
