Myton School posted on Facebook: 'Parents and carers, this morning we received a vague threat via email against our school.
'As always the first priority was the safety of students and staff, who were all evacuated from the buildings.
'We appreciate the communication was difficult at this time as we had such limited access to systems.
'Thank you very much for your prompt responses which allowed us to send Year 7 to 10 students home.
'We are working on a plan to get Year 11 and above students home as they were evacuated out of exams without their phones and other personal belongings.'
The school also thanked its staff, pupils and police for their response to the situation.
Chief inspector Faz Chishty, local policing commander for south Warwickshire, said: 'Thank you to everyone for your patience and understanding while we respond to this incident.
'I'd like give credit to the staff and students for how they responded. Police will remain at the scene for some time. We will keep you updated.'
