Big Brothers Big Sisters' Project Hope matches caring adult mentors with 100 youth in foster care. Mentors provide a consistent and caring adult in the lives of children who have experienced, and may continue to experience, major changes in their lives. Mentors help with homework, share mutually enjoyable activities and support children in foster care as they cultivate relationships with foster parents and biological parents. Nearly all of the children involved improved their family relationships, while three fourths improved their classroom behavior and participation and more than half avoided substance abuse and involvement with the juvenile justice system.
