Upon his re-election in 2006, then-New York City Mayor Michael Bloomberg and Schools Chancellor Joel Klein offered the free use of underutilized school facilities to a bumper crop of charter schools opening that year—including my first. Fueled by this policy, charter-school enrollment in the city grew from 11,000 to almost 70,000 by the end of Mr. Bloomberg’s second term in 2013, and my one school grew to 22.
As the founder and CEO of Success Academy Charter Schools—free public schools open to all children in New York City through a random lottery—I’ve seen firsthand how allowing “co-location” with district schools has helped charter schools and their students thrive. Success Academy currently has 32 schools spread across the Brooklyn, Bronx, Manhattan and Queens boroughs and recently was granted approval from our chartering authority, the State University of New York, to open 14 more.
