Page 17 of the 2005 government report which you can download here http://www.ofsted.gov.uk/inspection-reports/find-inspection-report/provider/CARE/SC024584 states that:

The school had some rules about internet use, regarding the issue of viewing and making screen savers of adult material. However the school had not responded to the issue raised at the last inspection regarding the lack of safeguards for young people using the internet. It was noted by the inspectors that the school had made a clear statement in the information provided to parents of boarders that access to the internet is not restricted at the school. The principal reported that the school had been advised that protective software was easily overridden, and that the system the school had in place, of supervision by each other, and the promotion of individual responsibility was sufficient. Due to the potentially serious nature of this issue, further recommendations have been made that the school produce a written risk assessment for the use of the internet, and a protocol be produced enabling the school to monitor the sites accessed by pupils via the schools computers.
