Around 150 firefighters tackled the blaze
A school in West Yorkshire partly ravaged by fire will not reopen until the start of the new term in January.
The fire at Carleton Community High School last month damaged the library, drama studio, gym, reception, administrative block and 120 computers.
Wakefield Council said arrangements had been made for the school's 972 pupils to be taught elsewhere.
Police said a 15-year-old boy was arrested on suspicion of arson and had been released on bail.
West Yorkshire Fire and Rescue Service and the police were still investigating the cause of the blaze.
The authority said as of next Monday pupils would be taught for three hours a day at the nearby King's High School by teaching staff from Carleton.
Provisions were also in place to enable scheduled mock exams to be held.
Head teacher Rob Foreman said: "The education and welfare of students is absolutely paramount so we have put these plans in place to make sure lessons can be delivered.
"Everyone at the school is still coming to terms with what has happened, but we are planning for the future."
Councillor Pat Garbutt, cabinet member for children and young people, praised the efforts of everyone affected by the fire.
"The support the school has received during this difficult time from the pupils, parents and community has been fantastic and this fire will not keep us down."
The authority said work on site was progressing well and it was hoped the school would be reopen next term.
