Children in primary schools in Bexley now have their own passports, which show that the students can adopt a healthy lifestyle.
The documents were issued after the children had completed one health-related task a day.
Schools in the area hope the scheme will help kids learn about the benefits of eating well and exercising, and encourage them to walk to school.
The initiative was run in conjunction with Bexley Council's Walk to School initiative.
School travel co-ordinator Jennifer Counsell, said: "We worked closely with our colleagues in the Healthy Schools team and Bexley School Sports Partnership to provide support, help and advice to schools, parents and children on the issue of travel to and from school."
Pupils of schools in the area completed marching tasks, to encourage walking; tasting trials, to help them consider healthy food; walk and talk, to promote the social aspect of walking and thinking practices that help them consider personal safety and to better understand roads.
The government acknowledges there are health benefits to walking to school, but as all teaching assistants
are aware, it is children's safety that is paramount.
