The school behind a six-week long consultation will become an academy in May this year, despite protests to keep it a city council school.
Education Secretary Michael Gove, has defended his decision to take over a school in Derby because of "serious concerns" about standards.
Teachers at a school in Derby have defended their decision to go on strike over plans by the Government to turn it into an academy.
Teachers at a Derby secondary school are poised to take strike action over plans to turn it into an academy.
Last month, the Education Secretary Michael Gove replaced the governing body at Sinfin Community School with an interim executive board following concerns about poor educational standards.
The board is due to consult soon about academy conversion, with Nottingham-based Greenwood Dale Foundation Trust the likely sponsor.
The National Association of Schoolmasters Union of Women Teachers (NASUWT) says the board refused to withdraw its conversion plans at a meeting yesterday.
The union will now consult its members about industrial action before Christmas.
75% of NASUWT members at the school voted in favour of strike action in a ballot last month.
The Department of Education has defended its intervention at the school and the move towards academy status.
