A top official at New York City’s largest charter network is leaving for another network, Success Academy officials confirmed Monday.

Kris Cheung, the chief operating officer at Success Academy, is headed to Texas for an operations job at KIPP. Rob Price, Success’s chief financial officer, is also leaving his post. The moves were first reported by Gothamist.

“As Success scales to 100 schools, we have hired several new leaders this past year — general counsel, chief of technology and head of leadership and human resources,” Success spokeswoman Ann Powell said. “While Kris Cheung, who has spent seven years with Success, is leaving to work in Texas for another charter network, Rob Price will continue as a consultant.”

Cheung was promoted to oversee operations in the shake-up that followed a 2015 school-supply fiasco required network staff to work nights and weekend days sorting boxes and furniture on Long Island.

The moves leave the network, which has ambitions to grow to 100 schools, with key positions to fill. Dan Loeb, Success’s board chair, also stepped down recently (and was replaced by Steven Galbraith); founder Eva Moskowitz lost another key ally in Emily Kim, the network’s former top lawyer, in 2017.

The city’s 46 Success Academy schools are known for their high test scores, strict discipline, Moskowitz’s fights with Mayor Bill de Blasio, and controversies around pushing out students and a much-publicized video showing a teacher ripping student work.

KIPP spokesman Steve Mancini said Cheung’s precise role is still being decided. That network’s well-known co-founder, Mike Feinberg, was fired in February after a sexual misconduct investigation.
