The department does not collect data on the number or purpose of school trips abroad or exchanges undertaken by schools. School staff accompanying pupils on school trips abroad will have had Criminal Records Bureau checks as part of the recruitment process for their employment and do not have to have further checks before taking part in such activity. The department's strong recommendation relating to volunteers who are in unsupervised contact with children, including those accompanying pupils on school trips, and new host families who provide care for students from overseas should be CRB-checked. We cannot impose this requirement on host families in other countries who provide care for British children. However schools should satisfy themselves that adequate safeguarding arrangements have been put in place to protect children. Under the new vetting and barring scheme those who provide care and accommodation for children under 18 for reward or by arrangement made outside the family will be engaged in “regulated activity”, and this is made clear in interim guidance the Government issued on 12 October 2009 about the new scheme.
