“In a rigorous comparison study, we found that girls who participate in the Girls Inc. Experience demonstrated improved academic performance, school-related behaviors, physical activity, and leadership outcomes.“ – Dr. Deborah Moroney, Managing Director of the American Institutes for Research

“[G]irls participating in Girls Inc. were more likely to engage in activities and express beliefs that lead to physical and mental well-being, academic achievement, and the development of leadership skills… [They] had consistently higher math test scores than the comparison group of girls…[and] Girls Inc. girls reported more positive attitudes and behaviors than the comparison group…” – Dr. Allison Dymnicki & Melissa Yisak, AIR Research Team 

This study documents the ways in which girls are benefitting from Girls Inc. programming. The ultimate intent: to show what difference a high-quality Girls Inc. Experience makes in the lives of girls. From 2017 to 2019, the American Institutes for Research implemented a quasi-experimental research study with four Girls Inc. affiliates and their school districts in small, medium, and large communities that were reflective of the larger Girls Inc. network.

The results are truly compelling, documenting with strong evidence that Girls Inc. changes the trajectory of girls’ lives and sets them up for life-long success. The results validate what we have known all along: Girls are innately powerful, and they are the strong, smart, and bold leaders our future needs. When girls are given the tools and opportunities to succeed, not only do they change their own circumstances, they also change the circumstances of others around them. THEY CHANGE THE WORLD.
