A survey of teachers has found that the behaviour of school children is improving.

The Behaviour in Scottish School Research, which was carried out by Edinburgh University, found that the most common behaviour issue is "low level" indiscipline, such as running in corridors and talking out of turn in class.

About 90% of teachers said all or most pupils are generally well behaved around schools, reflecting "positive" changes since the last survey three years ago.

Most teachers are confident that "serious indiscipline" does not substantially impact their schools.

The report found that physical violence by pupils on teachers is very rare but noted it was more common between pupils.

Ronnie Smith, general Secretary of the Educational Institute of Scotland teachers' union, said: "The improvement in discipline identified in the report is partly a result of the high priority given to tackling this issue by a succession of ministers.

"Therefore, it is essential that there is no let-up in the priority given, or the resources invested, in improving  school discipline.

"Any cuts to education funding would only put at risk all the progress made to date."  

More than 3,500 teachers took part in the survey, described by the Scottish Government as the most accurate and comprehensive picture of pupil behaviour ever produced.

Schools Minister Keith Brown said: "Across Scotland, schools and local authorities are working hard to improve the behaviour of pupils and this research highlights the many effective approaches taken to promote positive behaviour."
