19 states still allow physical punishment in schools

Washington Post - A federal data analysis found that on average, one child is hit in public school every 30 seconds somewhere in the United States.

While 31 states have now banned corporal punishment, these states still allow it: Alabama, Arizona, Arkansas, Colorado, Florida, Georgia, Idaho, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas and Wyoming. In many places, parental permission is required — and often given. It is more prevalent in Texas; least prevalent in Wyoming. The last state to abolish it was New Mexico, in 2011.
