School policies and school environment
• Ensure school policies and school environments en-courage physical activity and a healthy diet. Consider�building layout�provision of recreational spaces�catering, including vending machines�food brought into school by children�the curriculum, including PE (physical education)�school travel plans, including provision for cycling�extended schools
Staff training
• Teaching, support and catering staff should have trai-ning on how to implement healthy school policies
Links with relevant organizations
• Establish links with health professionals and those in-volved in local strategies and professional partnershipsto promote sports for children and young people
Interventions
• Introduce sustained interventions to encourage pupilsto develop life-long healthy habits. Short term, one-off events are not effective on their own
• Take pupils’ views into account – including differencesbetween boys and girls and barriers such as cost orconcerns about the taste of healthy food
• PE/sport staff should promote activities that childrenenjoy and can take part in outside school and conti-nue into adulthood
• Children should eat meals in a pleasant sociable envi-ronment free from distractions
• Younger ones should be supervised; if possible, staffshould eat with them
• Involve parents where possible; for example through spe-cial events, newsletters and information about lunch menus
