In our work with families here at the school we often discuss the advantages in offering an all girl environment, which is easy enough because we see it every day. The remarkable support and empathy of a community composed entirely of girls, the small victories in growing self-confidence and the larger achievements as girls exceed their own best results and stand up to lead their peers --- this is some of the magic that we get to observe here at SMS. But with our relatively small sample (as a school of 360 - 380) it's harder to quantify the larger trends and long-term impacts of providing single-sex learning opportunities. That's why it's exciting to have partners like the National Coalition fo Girls' Schools (NCGS), who compile stats from schools and researchers around the world. The NCGS just released a video that presents the girls' school advantage "by the numbers". Take a look!
