Chang replaced Carol Johnson as Superintendent of Public Schools in Boston, who had announced her retirement in April 2013. His candidacy had been favored by Boston's mayor, Marty Walsh until multiple controversies saw the Mayor's support drop until his resignation in June 2018.[3] Chang attempted to change start times for all schools in December 2017, a decision that was protested by parents and community members before it was reversed two weeks later.[citation needed]
Resignation
Chang resigned after lawsuit was filed by student rights groups and the Lawyers' Committee for Civil Rights and Economic Justice, a law office in Boston, Massachusetts alleging improper information sharing between BPS and ICE - a claim which Chang vigorously denied in a letter to the BPS community.[4] It was also alleged[5][6] that Chang kept quiet about IRS audits into the student activity fund in 2017, which drew tension with the Boston school committee.
