The STEM Learning Ecosystems Initiative cultivates and supports 56 Ecosystems working to improve access to high-quality STEM learning for all students. Launched in September 2015 by the STEM Funders Network, the Initiative empowers communities to bring together unlikely local partners and create systemic change to ensure more students, particularly underserved and underrepresented students, develop the STEM knowledge and skills they need to learn and thrive in today’s workforce.
