Talk with your child's teacher or a school administrator to understand the situation and the circumstances of the misbehavior. Ask questions and get detailed answers so you know what happened. Find out if this is an isolated event or if the school notices a pattern of misbehavior.
Sit down with your child to discuss the misbehavior. Talk about what you learned from the school officials and ask your child to tell you about what happened in her own words. Try not to interrupt or interfere as your child talks because you may learn valuable information about how your child is feeling or about what motivated your child's behavior.
Make the punishment fit the crime. If your child hurt another child at school or did something else equally serious, impose a consequence that will get your child's attention and discourage similar behavior. For example, your child may lose his television privileges or gaming privileges for a period of time (several days or up to a week) or she might need to miss a special event. On the other hand, if your child has just been disrupting class, the punishment might not need to be as severe. A similar loss of privileges for a shorter time might be effective.
