Martial arts expert Steve Jones claims victims of bullying using self-defence against their tormenters might actually make matters worse.
His comments come after news the father of a student at Thorns Community College in the West Midlands is attempting to sue the school for costs towards her self-defence lessons.
She began the classes after she started being bullied in September; and her father says the school has failed to protect her.
But Jones, whose career in martial arts spans more than 35 years, warned that while self-defence may improve the confidence of the victim, it could make the physical violence worse.
"You may end up escalating the violence to a place [that ends] with more aggressive attacks," he told Julia Hartley-Brewer. "If there are two or three people bullying another person, self-defence moves are not going to help.
"To actually be able to use it in a real situation takes a high degree of training."
The internationally renowned martial arts teacher believes schools need to do more to educate children in how to put a stop to bullying.
"You need to be able to stand up for yourself without becoming aggressive," he added. "Use the school as the weapon. The child needs to know there is a clear procedure in place to deal with bullying."
