After more than 50 years in Miami, we've seen that the Big Brothers Big Sisters approach to 1:1 mentoring works. It changes the lives of the Littles being mentored, as well as the life of the Big developing a relationship with his or her little. We've seen underperforming students transform to valedictorians, lack of direction transform to purpose, and hopelessness turn into possibility. Research from the 2014-2015 academic year demonstrate the tangible impact of the Big Brothers Big Sisters approach to mentoring - and can offer a sense for the "return" on your investment of time or financial resources. 87.29% of students improved or maintained academic performance 76.27% of students improved or maintained school attendance 94.41% of students showed improvement in behavioral evaluation 99.66% of students were promoted to the next grade level And of course, there's also the immeasurable, intangible but invaluable emotional impact of the program on its participants.
