It has been a year since a fire ripped through Selsey Academy near Chichester and now there are calls for all schools to be fitted with sprinklers.
Since 2010, less than 40% of new build schools have had sprinkler systems installed.
Sussex Fire says the devices wouldn't have prevented the flames spreading at Selsey because the fire started on the roof.
As Chloe Oliver reports.
Chloe spoke to Tom Garfield, Headteacher at Selsey Academy and Maisie Rudkin from West Sussex Fire and Rescue Service.
