6 School policies and school environment Ensure school policies and school environments encourage 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 training on how to implement healthy school policies Links with relevant organizations Establish links with health professionals and those involved in local strategies and professional partnerships to promote sports for children and young people Interventions Introduce sustained interventions to encourage pupils to develop life-long healthy habits. Short term, oneoff events are not effective on their own Take pupils views into account including differences between boys and girls and barriers such as cost or concerns about the taste of healthy food PE/sport staff should promote activities that children enjoy and can take part in outside school and continue into adulthood Children should eat meals in a pleasant sociable environment free from distractions Younger ones should be supervised; if possible, staff should eat with them Involve parents where possible; for example through special events, newsletters and information about lunch menus Figure 10.
