Between 1992 and 2002, nationwide violent crimes at schools against students aged 12 to18 dropped by 50%.
Between 1994 and 2002, the youth arrest rate for violent crimes has declined 47% nationally.
From 1974 to 2000, the number of students suspended out-of-school increased from 1.7 million to 3.1 million. Research conducted over the past five years has detailed the growing use of suspensions for trivial conduct, much of which is subjectively labeled “disrespect,” “disobedience,” and “disruption.”
While national data is not available, data from various districts indicate the growing trend toward using arrests to address school disciplinary matters. For example, the number of arrests in Philadelphia County schools has increased from 1,632 during the 1999–2000 school year to 2,194 in 2002–2003.
In 2002, of the 4,002 arrests of youths by Houston Independent School District Police, 660, or almost 17%, were for disruption (disruptive activities, disruption of classes, and disruption of transportation). Another 1,041 arrests, or 26%, were for disorderly conduct.
