Some children repeatedly get themselves in trouble at school and at home.
They move constantly about and disrupt classes or they don't pay attention to factors that are going on around them. Because they pay little attention to their school work, they do poorly in school and because they constantly disrupt classes, they are criticized by their peers and teachers and often prevented from attending regular classes. As a result, they suffer from poor school performance, frustration and low self esteem. There are no laboratory tests to diagnose this condition. If they misbehave at school, but not at home, they probably have a behavior or emotional disorder.
