The aim of this research was to investigate the approaches being taken by local authorities (LAs) and partner organisations to improve how young people are perceived, especially in relation to crime and antisocial behaviour. The study also looked at the challenges for and benefits of activities aiming to improve public perceptions of young people, and the methods used to measure the impact of these activities. The project's methods included initial desk research of policy documents, research papers and media reports. There were telephone interviews with staff from 20 LAs including personnel from integrated youth support and development services, youth offending services, crime and disorder reduction partnerships and community safety partnerships. Three case studies involved interviews with frontline staff and young people. This study raised a number of issues that can be taken forward by policy makers and strategic leads at both national and local level. These include the need to: (1) undertake a local audit of activities already under way designed to impact positively on perceptions. This will support future strategic planning and co-ordination; (2) measure the impact of activities more systematically in order to provide clearer direction for those developing, commissioning and championing work locally; (3) develop further the skills and knowledge of operational staff with local or regional training activities, toolkits and guidance documents; and (4) provide a policy steer that is specific to youth perceptions and underpinned by legislation requiring agencies to work together. The case studies are appended. A glossary is included. (Contains 2 figures, 1 table, and 8 notes.)
