We are here to Start Something Big!

Big Brothers Big Sisters is not your typical organization. We help children realize their potential and build their futures. We nurture children and strengthen communities. And we couldn’t do any of it without you. Since 1967, each time Big Brothers Big Sisters of Flagstaff has paired a child with a role model in a supported relationship built on trust and friendship, it can blossom into a future of unlimited potential. And thanks to the first-ever nationwide impact study of a mentoring organization, we have the facts to prove it.

The Study

Public/Private Ventures, an independent Philadelphia-based national research organization, looked at over 950 boys and girls from eight Big Brothers Big Sisters agencies across the country selected for their large size and geographic diversity. This study, conducted in 1994 and 1995, is widely considered to be foundational to the mentoring field in general and to Big Brothers Big Sisters Community-Based program in particular.

Approximately half of the children were randomly chosen to be matched with a Big Brother or Big Sister. The others were assigned to a waiting list. The matched children met with their Big Brothers or Big Sisters about three times a month for an average of one year.

Researchers surveyed both the matched and unmatched children, and their parents on two occasions: when they first applied for a Big Brother or Big Sister, and again 18 months later.

The Results

Researchers found that after 18 months of spending time with their Bigs, the Little Brothers and Little Sisters, compared to those children not in our program, were:

  • 46% less likely to begin using illegal drugs
  • 27% less likely to begin using alcohol
  • 52% less likely to skip school
  • 37% less likely to skip a class
  • 33% less likely to hit someone

They also found that the Littles were more confident of their performance in schoolwork and getting along better with their families.
