A big increase in the number of primary school children suspended for violent acts is being blamed on the removal of corporal punishment in schools.
Figures from the Ministry of Education show a 88 per cent increase in suspensions of eight-year-olds from 2000 to 2008 for assaults on classmates, a 73 per cent rise for seven-year-olds, a 70 per cent increase for six–year-olds while the suspensions over the same period had increased by 33 per cent for five-year-olds.
"It is significant that as schools have removed corporal punishment, schools have become more violent," Family First national director Bob McCoskrie said today.
