A Wolverhampton school damaged in a suspected arson attack should reopen as planned in September, a council said.
Fire broke out at Elston Hall Primary School, Stafford Road, at about 2010 BST on Monday.
It was brought under control three hours later and staff were able to re-enter the building in Fordhouses on Tuesday to view the damage.
Wolverhampton City Council said the fire had delayed planned repair work, but school would start on 6 September.
The fire affected a corridor, four teaching rooms, three administration rooms and the library.
The school would reopen as planned, although it was likely that temporary accommodation for pupils will have to be provided, a spokesman said.
"We will be contacting parents through the usual channels as and when the situation becomes clearer," the spokesman added.
The school has 482 pupils at primary and infant level and 39 children in the nursery.
An 11-year-old boy was arrested on Monday on suspicion of arson and has been bailed as inquiries continue.
