Big Impact – Proven Results

Research Suggests Mentoring has a Positive Effect on the Whole Child


Research shows that by engaging communities, schools and families, Big Brothers Big Sisters helps youth achieve positive outcomes in a broad range of areas that experts say really matter. While programs that focus on education, behavior and socio-emotional growth exclusively are extremely important, this report supports our focus on developing the whole child. We are heartened by the results we are seeing for youth during their middle school years, a time when attitudes towards risk and school can shape the future.
