Children who are prone to angry outbursts or who behave aggressively toward their peers or teachers can cause problems in the classroom. 

Not only is the education of other students jeopardized because of disrupted lessons, but these other students may experience anxiety about the on-going chaos caused by acting-out kids.

Children who are angry and aggressive may be frustrated and upset, but may lack the social cognition skills necessary to understand interactions with others or to engage in problem solving. They are at high risk for school failure because their behaviours interfere with their learning and because they may have underlying learning disabilities.

Children with severe behaviour problems are often suspended or expelled from school, further disrupting their education.
