1. Collaborative Relationships: We believe in the power of collaborative relationships, and that when people come together lives are changed for the better. 2. Respect: We believe that respect is shown through courtesy, kindness, embracing differences and valuing diverse experiences. 3. Accountability: We are committed to being accountable for ourselves, including our attitudes, our program results, and how we utilize our resources. We believe that when people are consistent and reliable, it builds strong relationships with a foundation of trust. 4. Safety: We adhere to strict safety standards in screening and training our volunteers, in our youth activities, and in supporting our Big/Little matches. We seek to be a safe haven for all children and families in our community. 5. Self-Determined Potential: Self-determined potential means empowering every child to define success for themselves. We believe that with support, every child can define and achieve success in their lives.
We measure impact in the number of children served, the longevity of the mentor relationships, and positive outcomes for participating youth. Our local mentor relationships are lasting an average of 41 months, well above the national average. Each year we participate in independently designed and nationally administered Youth Outcomes Surveys to measure outcomes in areas of behavior, attitude & school performance, comparing kids’ latest responses to those they gave at first intake. We aim for a minimum of 80% of youth participating for at least one year to show improvement or positive stability in each of those areas. In fiscal year 2019 kids maintained or improved in the following areas: 89% educational expectations, 86% scholastic competence, 92% grades and academic performance, 94% parental trust and family connectedness, 86% social acceptance and 98% attitudes toward risky behavior.
