Lessons have resumed at Campion School after a fire broke out in a woodwork building at lunchtime.
Fire crews were called to the Sydenham Drive School just before 1pm on Wednesday after reports of flames in the design technology block.
The fire is thought to have been cased by woodcutting machinery, leaving half of the small space smoke logged.
Nobody was hurt in the incident, and pupils were returned to lessons within the afternoon.
A spokesperson from Warwickshire Fire and Rescue Service said: “Upon arrival crews confirmed that there was a fire involving woodcutting machinery in the technology block at the school.
“This building is approximately twenty five metres by twenty five metres.
“Fifty percent of the building was smoke logged.”
Teams from Leamington and Southam attended, and remained on scene into the afternoon.
