Seeking fundamental changes in access to and equity in science, technology, engineering, math and medicine (STEMM) education, the White House Office of Science and Technology Policy (OSTP) and participants from across sectors met and sought ways to ensure the STEMM ecosystem is equitable and inclusive. OSTP, along with the American Association for the Advancement of Science (AAAS), and with support from the Doris Duke Charitable Foundation (DDCF), have launched the STEMM Opportunity Alliance (SOA), a national initiative to lead and coordinate this and future cross-sector action to achieve equity across STEMM fields. To date, more than $4 million has been committed to launch SOA with more than 90 partners signing onto the effort.
