(FOX 26) - Seventeen people are dead and more than a dozen injured after a former student opened fire at Marjory Stoneman Douglas High School in Parkland, Florida.
Everytown for Gun Safety says this is the 18th shooting at a school since the start of 2018. That number includes shootings where guns were fired accidentally, no one was injured, suicides, and shootings near campuses.
Three were in Texas, including one where a teen at Italy High School shot a girl four times over a breakup.
The non-profit organization says there have been more than 300 school shootings since 2013. That's an average of one per week.
Many are quick to point out that these gun-related incidents at schools are not what most would consider a school shooting.
As an op-ed in the Washington Examiner reads, "Using the term 'school shooting' to describe events in which the shooter intended no harm to anyone but himself, or where a gun was fired accidentally, is plainly misleading."
Whether they were school shootings or gun-related incidents, many people feel 18 is too many, that one is too many.
Here are the gun-related incidents at or near school campuses since the start of 2018:
