Maker Ed is a non-profit organization dedicated to creating more opportunities for all young people to develop confidence, creativity, and interest in science, technology, engineering, math, art, and learning as a whole through making. Through its support of educators and communities, Maker Ed plays a national leadership role in both broadening access to and deepening the impact of meaningful making and learning experiences for youth. Your contribution to Maker Ed goes towards connecting educators and communities through our growing network, providing professional development to educators, building capacity for making opportunities at organizations and in communities, and building and sharing best-practices and research efforts around maker education — bringing us one step closer to our vision of Every Child a Maker. Maker Ed is a project of the Tides Center, a registered 501(c)3 non-profit public charity.
