A Functional Behavioral Assessment (FBA) is a study of a child to find out why he or she is having behavioral problems. An FBA should include:

• Several observations of the child at different points of the school day,
• An interview with the child,
• Interviews with the child’s teachers, and 
• A review of the child’s discipline reports.

Usually, it will be done when a child has gotten into trouble repeatedly at school. If you're worried about your child's behavior at school, you can request an FBA. An FBA must be done if:

• The manifestation determination team decides that your child’s behavior is caused by his or her disability, 
• Your child is removed from school for more than 10 school days in a row,
• Your child has been removed from school for more than 10 school days throughout the school year, or
• Your child has been moved to an interim alternative educational setting.
