"Police are being called to schools about 40 times every week of the academic year to deal with behaviour teachers say they cannot handle.
Figures issued under the Official Information Act show officers were called out an average of 1531 times each year from 1998 to deal with violence, drugs or sex offences.
Last year, they were called 1658 times.
The number of calls over violent offences jumped 27 per cent in the past decade - from 869 to 1064.
Total school enrolments rose only 4 per cent from 2001 to 2009 and lobbyists say the rise in offences is alarming."
