TRI-STATE (WFIE) - You drop your son or daughter off at school with the expectation they will come home safe, but for many parents this is no longer happening.
There have been 144 school shootings in the United States since the Sandy Hook massacre in 2012.
14NEWS spent several weeks at five different Tri-State school districts to see what they're doing to keep students safe.
EVSC, Owensboro Public Schools, the Warrick County Corporation District, and the Hopkins County School District all have security cameras inside and outside their schools. Only some of Henderson County Schools have security cameras.
All five school districts also have liaison officers available in case of emergencies.
Only Warrick and EVSC schools have buzzer systems.
School officials say detailed emergency plans are reviewed every month and changes are made with every school drill.
Some even have committees with a goal of constantly improving safety.
