 The incentive scheme run in the intervention school consists of a prize draw taking place once a week. The prize is a 5 shopping gift voucher valid in a number of high street shops. Chances of winning depend entirely on the number of points: the number of active trips to school reported exclusively by the parent on the AST report form, through the same questions used at baseline. For each week day that they travel to school the child gets one point. This point is the equivalent to a ticket with the childs ID number that will then be entering the draw. Each child can earn between zero and five tickets per week, depending on the number of active travel trips to school reported by the parent. Discrepant numbers between parental reports and those reported by the child or recorded on the accelerometer are of great interest for measurement, but will be disregarded for the purposes of the draw. In the absence of the parent AST report, the child report may be use for point count, but the child will be reminded that the parental report will be necessary for the next draw.
