More than 1,100 pupils have been excluded from Leicester schools in the past three years accused of assault, verbal or racial abuse, bullying and sexual misconduct.
The figures were released by Leicester City Council following a Freedom of Information request.
Between 2010 and 2013, 1,113 pupils were permanently or temporarily excluded.
In 2012-13, there were 413 exclusions, 423 in 2011-12 and 445 in 2010-11.
Councillor Vi Dempster, assistant city mayor for schools, said: "Exclusions are always a last resort and we work closely with head teachers to tackle challenging behaviour.
"Behaviour which disrupts the education and achievement of other children and prevents teachers from teaching is something that will always be addressed in Leicester schools.
"While we will always do our utmost to deal with disruptive behaviour, we're determined to look behind to see why children and young people behave the way they do.
"Where possible, we work to alleviate the causes."
The city council said it has developed and adopted a number of behaviour strategies in past years. These include an anti-bullying strategy for schools and an anti-bullying community awards scheme.
This year, the city and county councils jointly worked with colleagues in Denmark to use restorative justice techniques in schools to tackle challenging behaviour – described by the council as "very successful".
It also has behaviour support teams which offer training and outreach support for schools and for pupils with challenging behaviour.
Extra support is offered to children with special educational needs and disabilities because they are statistically more likely to be excluded.
The council has set up a special schools panel where head teachers considering exclusions can meet other leaders and local authority officers to share knowledge and skills and try to avoid exclusion.
Any child at risk of exclusion receives a support plan.
Councillor Dempster said: "We know encouraging schools to work together achieves results, which is why our head teachers' panel can be a very effective way of preventing exclusions.
"We're also trying out innovative techniques such as restorative justice to deal with problems such as bullying.
"We'll continue to support schools and families to ensure, wherever possible, behavioural issues are tackled as soon as they occur."
