A statement on their website has confirmed a number of staff members are unable to make it into work.
Dronfield Henry Fanshawe secondary school won't be open for the foreseeable future.
In a statement on their website-which was posted yesterday evening-the headteacher there has confirmed they're following Government guidance.
You can read it here in full;
"It is with great regret and sadness that we have taken the decision to close the school until further notice.
Following the Government announcement today of who should self-isolate or ensure social distance, we have analysed the staffing and concluded that there is a significant number of staff who will not be able to come to school.
This means that it will not be possible to function safely and securely as a school, nor provide the appropriate provision that is required. We are deeply apologetic for this as we know the inconvenience this will cause.
Work will be set for students and there will be communication during the day on Tuesday to provide further details. We wish you the best of health in these unprecedented and difficult times."
