A recent study puts the blame for a child's bad or erratic behaviour in the classroom squarely on his/her parents.
A survey of over 8,000 members by the NASUWT Teachers Union found that more than two in three teachers identified poor back-up from parents as the most common factor for student misbehavior.
The negative influences of television and media were also blamed by teachers.
"Parents can't simply abandon their responsibilities at the school gate," BBC quoted NASUWT leader, Chris Keates, as saying.
"Teachers are not receiving the support they need from parents, school leaders or government to assist them in maintaining high standards of pupil behaviour," Keates added.
