Beaverwood School for Girls is changing its name to Chislehurst School for Girls following last month’s alleged chemical attack.
News Shopper reported on March 12 how two girls were arrested on suspicion of possessing a prohibited weapon following an incident in the school playground which left one girl requiring hospital treatment.
At the time the girl's mother, Kerry Finch, 30, of Mottingham Road, slated the school's handling of the situation.
She said the Beaverwood Road school failed to inform her of the incident until hours after it had happened and failed to take her daughter, Paris, whose "whole face was completely burned", to hospital.
She told News Shopper: "The school neglected to call for three hours after my daughter’s face had been burned.
"I jumped in my car and went down there.
"When I got there her whole face was completely burned, her cheeks were blistered.
"The teachers neglected their duties.
"They had no right to delay my daughter's treatment for three hours. Maybe then she wouldn't have blistered on the cheeks.
"She was left in a room with a tissue.
"I was in shock that they did this to my daughter."
Following the incident headteacher Karen Raven said: "Beaverwood School for Girls is proud of the calm and sensible way in which the isolated incident was dealt with by students and staff.
"It is business as usual for the school community as exams are underway.
"At break time, a teenager randomly sprayed a can, the contents of which accidentally caught some of her friends.
"Only one student was treated in hospital. No other students were involved.
"The school continues to take all appropriate actions."
A spokesman for Beaverwood School said: "The decision to change the name to Chislehurst School for Girls pre-dates this by several months, having been passed as a resolution of the full governing body meeting on December 4 2013."
The two girls who were arrested, aged 13 and 14, were bailed until April 25.
