Schools in Southwark will not exclude students for behaving badly, according to council documents.
Secondary schools in the south London borough will agree to keep disruptive children, unless they put another child's safety at risk.
Southwark Council is said to be the first local authority in the UK to have schools sign up to such an agreement.
A 2020 report by the council found Southwark to have a higher than average exclusion rate.
