CLEVELAND -- After the Success Tech Academy shooting in 2007, many procedures changed in the Cleveland Schools.

The most visible changes came with metal detectors in every school and more security officers. But behind the scenes is something just as important.

The district now trains all staff to spot students who may be struggling with emotional issues.

They believe that it is working because serious incidents are down more than 40 percent over the past five years.
