'Successful schools will be forced to take a share of disruptive
pupils to prevent them from monopolising the best-behaved children,
the Government announced yesterday.
Ed Balls, the Children's Secretary, said that schools which excluded
pupils would have to accept the same number that had been expelled by
another school. This "one out, one in" policy would prevent
oversubscribed schools from dumping badly behaved children on to their
less successful neighbours.'
