A coalition of organizations led by the Indiana Youth Institute is launching a campaign to recruit hundreds of mentors for at-risk children across the Hoosier State.Insititute President Bill Stanczykiewicz says one of the many goals of the effort is too boost the state's lagging high school graduation rate."Research backs up common sense that kids who have a caring relationship consistently with a mentor--one adult, one child, one hour a week--do better in school, live healtier lives and do better as adults. So the impact is significant," he said.Volunteer mentors are asked to spend one hour per week with a youngster, helping with school work or just providing encouragement.
