All 1,690 students of the school have been asked to go home and return on Friday, May 27.
On Thursday, May 19, a fire gutted the girls' dormitory, a one-floor storey building, which accommodated 647 students and destroyed all student beds and belongings of the girls.
The fire also caused extensive damage to the building.
The cause of the fire is not yet known, but it is suspected that a water heater, which was plugged into the building, could be the cause.
The Tolon District does not have a functioning Fire Station.
Mr Issifu said an existing classroom block, which was not being used, would be quickly converted into a dormitory for the girls when they return on May 27.
