Staff at Heanor Gate Science college are set to go on strike next week.
The news follows an announcement by the school that it could become an academy.
It has yet to submit a formal application to apply for academy status and consultations with parents and staff began this week.
Thirty-eight teaching staff at the school, who are members of teaching union NASUWT are due to strike on Tuesday, March 15.
A statement issued to parents by head teacher Rob Howard and chairman of governors Andrew Collington on Monday, March 7 said: “The school is currently looking at how best it manages the situation. It is likely that not all students will be able to attend school on that Tuesday and we can only apologise for any disruption caused.”
The news comes after the school was given an ‘outstanding’ grade in its recent Ofsted report.
A report given to pupils after the inspection reads: “Despite the ageing and dilapidated building that you put up with everyday, you should be proud that you attend a school that provides you with an outstanding education.”
Head teacher, Rob Howard was delighted at the results.
He said: “It is a real credit to the school and the hard work the staff and students have put in. It is also a real lift for the community to say we have an outstanding school on our doorstep.”
The specialist science college is currently entering into consultations with staff and parents about switching to academy status.
