The city's Department of Education has announced yet another high-profile departure.
Deputy Chancellor John White is heading to Louisiana.
He is leaving to become the superintendent of the recovery school district in New Orleans.
White was head of the Department of Education's talent, labor and innovation division.
He is the fourth deputy chancellor to step down since Black was appointed last fall.
Deputy Chancellor Santiago Taveras resigned on Monday.
Schools Chancellor Cathie Black called the news of White's new job "bittersweet" but a compliment to the great work of the city's public school system.
A NY1 Marist poll Monday found just 17 percent of New Yorkers approved of the job Black is doing.
