Teaching union NASUWT said the increase in the number of pupils being suspended for assaulting school staff reflected feedback from their members that levels of violence and abuse from pupils had increased since the pandemic.
"These figures represent the tip of the iceberg, as we know that in too many cases schools fail to deal effectively with serious assaults and attacks on teachers," said Dr Patrick Roach, NASUWT general secretary.
"Schools too need to respond to the increase in violent and disruptive behaviour by ensuring there are effective behaviour management policies in place to deal with and deter acts of violence and abuse and that sanctions are clearly and consistently enforced."
Meanwhile, a poll published last month by the National Association of Head Teachers (NAHT) of more than 1,600 of its members, found 82% had been abused by parents in the past year.
The survey said 10% had suffered physical violence.
