To ask the Secretary of State for Education and Skills how many assaults on staff by (a) pupils and (b) parents have taken place in each year since 1997; and in how many cases was a conviction obtained. 
As the hon. Member has been told in previous answers (on 19 December 2001, Official Report, column 402W and 28 January 2002, Official Report, column 128W), the Department does not collect this information. Injuries that lead to an absence from work of three days or more must, however, be reported to the Health and Safety Executive. Information available from the Executive shows that all reportable assaults in the education sector in Great Britain totaled 160 in 1999–2000, 171 in 2000–01 and provisionally 143 in 2001–02; there are no figures for the related numbers of convictions.
