Which schools have had the deadliest shooting incidents?

School shooting incidents vary in severity with some having no recorded casualties while others report dozens of fatalities.

A shooting incident is logged every time a gun is brandished or discharged on school property. Besides indiscriminate mass shootings, incidents will include accidental shootings, suicides, or shootings outside of school hours but on the grounds.

The 2012 shooting at Sandy Hook Elementary School in Connecticut remains America’s deadliest shooting with 26 being killed, followed by the 2022 attack on Robb Elementary School which left 21 dead. The third deadliest shooting incident was at Marjory Stoneman Douglas High School in Florida in 2018, which killed 17 people.

The historic figures show 368 children and teenagers have been killed (39 of them aged under 10), 1,272 have been wounded (40 under 10) and 80 have suffered minor injuries.

The youngest victims were just one year old.
