A school principals group says the Government should drop its plan to send young offenders to boot camps.
The Principals Federation says a clear message from a two-day meeting this week on bad behaviour in schools was that any programme introduced should be based on solid evidence it works.
The federation says the Government should heed evidence presented at the summit that boot camps don't work.
The meeting ended with a plan to tackle concerns about what schools say are increasing numbers of disruptive children and young people.
The plan includes intervening at an early an age as possible when problems arise, training teachers to manage extreme behaviour and more support for programmes that have been shown to work.
