As regards projects to improve the situation at certain areas, Halt cooperates in the national Safe School programme and, for example, provides information to shopkeepers’ associations.

Secondary prevention focuses on specific risk groups. Some examples in this respect include carrying out local prevention projects and participating in prevention and neighbourhood networks and justice in the community projects, in which inter-organisational cooperation is a central element. 

Other organisations with which Halt cooperates include the police, fire services, health authorities and the Royal Netherlands Football Association (KNVB); the largest sports federation in the country.
