QUEEN Elizabeth's Grammar School has issued a short statement to explain that a small fire had broken out at the school but that the pupils and staff were all safe and that the afternoon would continue as normal, closing at 3.55pm.
Staff at the Green Road school evacuated all pupils from the site on to the school field below the century-old building after the fire broke out shortly before lunch time.
A spokesman for the school said: "We have had a small fire at school. Everyone is safe and the students are now having lunch.
"This afternoon will continue as normal and we will close at 3.55pm."
Fire and Rescue crews from Wirksworth and Ashbourne, along with an un-marked fire officer's car and a police car, attended the site while pupils waited in silence for instructions from teachers.
It is believed the fire started in a science room but further details will follow from Derbyshire Fire and Rescue.
Staff used a megaphone to explain to pupils that they were to return to the building for lunch, but they were only allowed to go in the canteen, the hall and the library. They started making their way back up to the buildings at around 1.25pm.
