According to the policy paper "Corporal Punishment in U.S. Public Schools: Prevalence, Disparities in Use, and Status in State and Federal Policy":
Children have been corporally punished in school for being late to class, failing to turn in homework, violating dress codes, running in the hallway, laughing in the hallway, sleeping in class, talking back to teachers, going to the bathroom without permission, mispronouncing words, and receiving bad grades . A review of over 6,000 disciplinary files in a central Florida school district for the 1987–1988 school year found that whether corporal punishment was used was not related to the severity of the student's misbehavior or to how frequently they had been referred for a rule violation. This study suggests that school corporal punishment is not necessarily used as a "last resort" for frequently misbehaving students or only for serious infractions.
Black children in Alabama and Mississippi are at least 51% more likely to be corporally punished than White children in over half of school districts, while in one fifth of both states' districts, Black children are over 5 times (500%) more likely to be corporally punished. Disparities for Black children are also high in several other southeastern states—17% in Arkansas, 20% in Florida, 26% in Georgia, 28% in Louisiana, and 18% in Tennessee meaning they were more than 3 times as likely to receive corporal punishment in school as White children.
The guidance being given now to children’s doctors by the American Academy of Pediatrics ought to be followed by all schools as well:
The AAP recommends that adults caring for children use healthy forms of discipline, such as positive reinforcement of appropriate behaviors, setting limits, redirecting, and setting future expectations. The AAP recommends that parents do not use spanking, hitting, slapping, threatening, insulting, humiliating, or shaming.
