According to Adams, despite the big increases in spending in the last 10 years, staff do not have the training and resources to deal with the increasing number of pupils who display problems. "It is true that some head teachers and local authorities do not take behaviour seriously enough and support teachers," he says. "But there is also not enough money to deal with these children. I had one class where eight of the 19 pupils had behavioural and emotional difficulties. When you're spending your time trying to separate them and keeping them in their seats, the level of teaching plummets."
