Many investigations into child abuse are handled on the local level by Child Advocacy Centers. Started over 25 years ago at what is now known as the National Children's Advocacy Center in Huntsville, Alabama by District Attorney Robert "Bud" Cramer these multi-disciplinary teams have met to coordinate their efforts so that cases of child abuse can be investigated quickly and efficiently, ultimately reducing trauma to the child and garnering better convictions. These Child Advocacy Centers (known as CACs) have standards set by the National Children's Alliance.
