All pupils from Rhyddings Business and Enterprise School are set to return to the school’s Oswaldtwistle campus from Monday.
Part of the school site was closed to pupils last month to allow necessary remedial work to be carried out to two of the schools buildings.
Since then some year groups have been taught in a self-contained area of Hameldon Community College in Burnley.
From Monday all pupils will be able to return to the Haworth Road school after alternative accommodation was brought onto the site and essential work was completed.
Work is still continuing on specific areas of the school, which will mean some room changes, but the curriculum will run as normal and pupil subject timetables will remain the same.
Lunches will be provided, with a reduced service in the first few days, but all pupils will receive a meal. Parents can also provide a packed lunch if they prefer.
Head teacher Andrew Williams said: “I would like to thank parents and carers for their patience and support during this period.
“I would also like to thank pupils and staff who have coped magnificently, as well as all the staff and pupils at Hameldon Community College who have been so welcoming.”
