Recently released federal data shows that U.S. schools have significantly raised security measures in recent years.
About two-thirds of public schools now control access to school grounds—not just the building—up from about half in the 2017-18 school year. Some 43% of schools have a “panic button” or silent alarm that connects directly with police in case of emergency, up from 29% five years ago.
A strong majority, 78%, outfit classrooms with locks, up from 65% a few years ago. Random metal detector use was reported in 9% of schools, with 6% using this equipment daily. Many schools have campus police, but just 3% arm teachers or other non-security employees.
Last year, more than 330 people were fatally shot or wounded on school grounds, up from 218 in 2018, according to the K-12 School Shooting Database, a research project that tracks incidents of a gun being fired or brandished on school property.
