Cwmcarn High School is to reopen, after Caerphilly councillors agreed a plan to remove asbestos at the site and provide temporary classrooms.
The decision was made at a meeting on Wednesday night, which was also attended by a large number of parents of pupils at the school.
Since the discovery of asbestos at the school last October, the pupils have been educated at the former Coleg Gwent site in Ebbw Vale.
