Girlstart’s mission is to increase girls’ interest and engagement in STEM through innovative, nationally-recognized informal STEM education programs. By empowering more girls to continue STEM studies, we can help address our nation’s STEM workforce inequities and impact innovation and economic development in America and across the globe. To accomplish its mission, Girlstart develops and implements a range of innovative, research- and standards-based education and mentorship programs designed to promote girls’ early engagement and academic success in STEM, encourage girls' aspirations and persistence in STEM education and careers, and incubate a talented and diverse STEM workforce. We are focused on serving girls of diverse ethnicities, girls who live in low-income or nonurban environments, and/or are considered at-risk. In 2016, we served more than 16,000 girls, teachers, and family members, 95% of whom participated at no cost.
