An initiative of Bloomberg Philanthropies and co-funders, Summer Boost first launched in 2022 in New York City and is expanding to seven new U.S. cities in 2023: Baltimore, Birmingham, Indianapolis, Memphis, Nashville, San Antonio, and Washington, D.C. The program is designed to support charter students completing kindergarten through 8th grade in select cities across the nation to accelerate their academic progress in English Language Arts and Math while providing engaging enrichment opportunities in summer 2023, in response to COVID-related learning loss. Schools can apply to receive up to $2,000 per student to support high-quality summer learning programs.
