Public/Private Ventures (P/PV) Impact Study Summary

This study, completed in 1995, found that a Little Brother or Little Sister who is matched for one year or more in a one-to-one friendship is more likely to graduate from high school, attend university, and demonstrate more respect for adults. Little Brothers and Little Sisters are also more likely to avoid alcohol, drugs and violence.

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

The results

The Big Brothers Big Sisters Match

Each match in the Big Brothers Big Sisters programme is carefully administered and supported by rigorous standards and trained personnel. Professional agency staff strive for matches that are not only safe and well suited to the child’s needs, but are also harmonious and built to last. Research has shown that matches are more likely to be successful when they are sustained over a long period of time, and studies on the Big Brothers Big Sisters programme have found the matches in the programme consistently spend more time together and continue as a match for longer periods than do their peers in other mentoring programmes studied by Public/Private Ventures.
