March 2020 was apparently the first March in nearly two decades without a school shooting in the United States. Schools across the U.S. have been shut down since early March as a prevention measure to slow the spread of coronavirus. Since then, kids of all ages have adjusted to homeschooling and online classes — a new normal that could extend through the rest of the school year. 

For most of those students, this is one of the longest stretches in their lifetimes without a school shooting. As first reported on Twitter by Washington Post reporter Robert Klemko, there hasn’t been a March without a school shooting since 2002 — the year most current high school seniors were born.

Data from the National School Safety Center and National School Safety and Security Services confirm that there have been school shootings every March since 2002. That year, a 13-year-old student brought a gun and a hit list to school but was subdued by a school resource officer deputy before he could pull the trigger.
