"States of concern" saw more than 1,800 incidents out of about 3,600 reported last year.
More than half of all incidents of violence and threats against schools took place in just 10 states during the 2017-18 school year, and New York is one of them.
According to the Educator's School Safety Network, those "states of concern" saw more than 1,800 incidents out of about 3,600 reported last year.
Following the mass shooting at Stoneman Douglas High School in Florida, researchers with the non-profit school safety organization pulled data from across the country to help find a solution.
They say schools may have plans in place for active shooters such as training for teachers and staff, but some of those programs don't get the money they need.
Back in March, the House passed the STOP School Violence Act giving schools and cities more than $1 billion to schools and local governments over the next 10 years help protect students.
Researchers say another key step to making a difference is to start thinking about violence in schools as an everyday concern, not just an occasional problem.
