One in four teachers does not think there is a good standard of behaviour in their school, according to Government research.

It reveals that many still believe that poor pupil behaviour is driving teachers out of the classroom, and suggests that those working in secondary schools are less positive than their primary colleagues.

The study, commissioned by the Department for Education (DfE) questioned more than 1,600 teachers about standards of behaviour in schools.

The findings show that while teachers are increasingly positive about behaviour, 6% overall still believe that it is poor, or very poor. And 19% said it is "acceptable".

Three in four (76%) said they thought behaviour was good or very good - a six percentage point rise compared to a previous survey in 2008.

In secondary schools alone, 8% of teachers said behaviour was poor or very poor, while in primaries it was 5%.

The majority of those questioned (85%) did say that they feel well equipped to deal with pupil behaviour. Half said that they thought appropriate training was available to those teachers in their school who struggle to manage difficult behaviour, while three fifths agreed that negative pupil behaviour is driving teachers out of the profession.

Schools Minister Nick Gibb said: "The majority of pupils are well-behaved and want others to behave well too. This survey shows encouraging effects of the Government's reforms, and that schools need to continue with their relentless focus on behaviour."

Ministers have introduced new measures to deal with unruly pupils including giving teachers more powers to search students and scrapping the 24-hour notice period for detentions.

Mr Gibb added: "The survey also reveals some concerns about negative behaviour, which is driving some teachers out of the profession. The Government is committed to maintaining our relentless focus on raising standards of behaviour in schools until every school is a safe and happy place in which pupils can excel academically."
