Several things are considered reasons for the drop in the number of students expelled for taking guns to Missouri’s schools. The number is down about 40% in the last three years. Federal programs coordinator Dee Beck with the state education department says reporting of incidents has improved. And, she says, more people are taking the issue more clearly. 27 of the 102 students expelled in the last school year were elementary school students. 58 were senior high school students. The rest were junior high or middle school students.
