A “practice” is defined as “an activity used by a site in the pursuit of improved outcomes for children exposed to violence.” In the Safe Start Demonstration Project, a “promising practice” is defined as a practice that has been implemented and has demonstrated the following characteristics: 1) preliminary evidence of effectiveness in local practices or activities (not necessarily across the initiative); 2) successful use in at least one of the 11 demonstration sites; 3) the potential for replication; and 4) an improvement over previous practices. Eight promising practices are discussed. They are 1) data-based decision-making; 2) improving the capacity to collaborate; 3) increasing awareness of children exposed to violence; 4) outreach into the community; 5) increasing identification and referrals; 6) engaging and retaining children exposed to violence and their families; 7) improving court responses to children exposed to violence; and 8) sustainability. The characteristics of each of these practices is discussed in the context of a demonstration site’s effort to prevent and reduce the impacts of children’s exposure to violence. Methods used in identifying and measuring the success of these promising practice are described. Appendixes contain a promising practice data matrix and ideas for outreach and education products.
