While there is a special court system to handle juvenile crime, there is usually not a special juvenile criminal code. Adult criminal codes are applied in the juvenile system, but the children are not generally accused of crimes. Instead, they are accused of committing delinquent acts. Sentences are designed to educate and rehabilitate children, rather than punish them. Children cannot be locked up in adult jails except for very limited periods of time. A child held in an adult jail must be out of sight and sound contact with the adult inmates. In earlier days, special crimes that only applied to children did exist. These crimes were the so-called status offenses and punished behavior that would not be criminal if committed by an adult. Status offenses included running away from home, skipping school, disobeying parents, and breaking curfew. The federal Juvenile Justice and Delinquency Prevention Act made receipt of federal funds conditioned on eliminating status offenses, and most states have done so. However, these behaviors may still trigger an investigation by child protective services to determine if the child needs assistance from the court or social service agencies.
