The K-12 School Shooting Statistics Everyone Should Know

The database documents every instance a gun is wielded, fired, or a bullet hits school property for any reason.

The Naval Postgraduate School‘s Center for Homeland Defense and Security (CHDS) released a K-12 school shooting database project as part of their Advanced Thinking in Homeland Security program. They found the need for accurate, detailed information on this subject was paramount.

The database documents every instance a gun is wielded, fired, or a bullet hits school property for any reason, regardless of the number of victims, time, day of the week, or reason. You can find the entire database here.

    This number is skewed. This makes it sound like there are actual attacks in schools or at schools when many of these are incidents that have nothing to do with attacks on the school or attacks on personnel or students. Look, any amount of shootings anywhere are too many but the way you are presenting it is not responsible. Thanks.

  2. Can you please tell me where your statistics came from in regards to the US having 82 school shooting incidents in 2018.
    One of the curriculums I teach is Active Shooter Response Training, along with the Aftermath and Recovery.
    Besides owning a business that provides this type of training, I work as the Public Safety Training & Education Coordinator for a large HealthCare Company (we have 9 hospitals in our system).
    I brought the Active Shooter program into our system, and I also do lots of research on active shooter events, and attend 10-12 webinars and in person seminars on the subject each year.
    I cannot find the number of school shooting incidents at 82, anywhere, some sources say we had 5, some say 7, but the most I’ve found is 11.
    The statistic of 82 seems far fetched to begin with, and was the reason I researched that number, I would be interested to know your source, please

      Hi Dominick,

      This database was put together by the Naval Postgraduate School’s Center for Homeland Defense and Security. Our article explains that this database is put together off of their definition of what makes an incident a “school shooting,” which they have defined as, when a “gun is brandished, is fired, or a bullet hits school property for any reason, regardless of the number of victims (including zero), time, day of the week, or reason.” This could be why the numbers you’ve found are different. All of the slides can be found here https://www.chds.us/ssdb/category/graphs/.

    “Firearm related incidents” is a far better, and more accurate title.

    This report is very skewed. Id the information is to be valid in determining the number of active violence on school grounds or related activities the reporting need to be broken down as follows.

    1. Number of incidents that involved enrolled students and occurring inside a school.
    2. Number of incidents occurring on school grounds during school hours involving students.
    3. Number of incidents occurring school hours on school grounds not related to enrolled students.
    4. Number of incidents occurring a school sanctioned sporting event.

    Additionally, breaking it out further to include weapon type and number of injured in each incident. Parameters should also separate known reason for violence. Eliminate things that are not directly related to the education of or sporting events for students gives a clearer picture to what is happening in our schools.

    I like the report the way it breaks down day of week, time of day etc. but we need accurate figures involving our students during a school sanctioned event.
