Exclusive: Summer Program Boosts Learning for Tens of Thousands of Charter Kids

A summer learning program called Summer Boost, operating in 460 charter schools across seven cities, helped 39,000 students gain an average of one month more learning in math and two and a half weeks in English language arts. Funded by Bloomberg Philanthropies with $50 million, the program aims to prevent the summer slide and has expanded from New York City to include cities like Baltimore, Nashville, and San Antonio.
