This school year, Illinois will become just the fifth state in the nation to prohibit corporal punishment in all schools. Legislation that Gov. JB Pritzker signed into law this month bans physical punishment in private schools while reiterating a prohibition on the practice in public schools implemented 30 years ago. When the ban takes effect in January, Illinois will join New Jersey, Iowa, Maryland and New York in prohibiting paddling, spanking or hitting in every school.
