Corporal punishment in public schools is legal in nineteen states in the U.S. Over 100,000 students are disciplined with corporal punishment in public schools each year. Little is known about the forms school corporal punishment takes or about how school corporal punishment relates to students’ outcomes. This study reports results from an anonymous online survey of emerging adults (ages 18 to 23) in the 19 states where school corporal punishment is legal. Of the more than 800 participants, 16% revealed that they experienced school corporal punishment. Propensity score matching was used to equate those who had experienced school corporal punishment and those who had not on a range of covariates. In regression models, having ever experienced school corporal punishment was linked with lower high school GPA, higher current depressive symptoms, and greater likelihood of spanking their own children in the future.
