The Assessment, Intervention and Moving-on Project (AIM) was set up in January 2000 to improve the way professionals respond to young people aged 10 to 17 years who display sexually harmful behaviour. The need for such an initiative was recognised as a result of a Greater Manchester study conducted by the Youth Justice Trust in 1998.
The study found that there were major shortcomings in the way these young people were assessed. As a result, the AIM assessment procedure (Print, Morrison and Henniker, 2000) was introduced as a key part of the AIM Project. The Youth Justice Board commissioned the Youth Justice Trust to carry out a two-year evaluation of the procedure.
