Alberto Carvalho is slated to be the next leader for New York City schools, according to a statement from Mayor Bill de Blasio. A spokeswoman for the Miami-Dade School District said Carvalho has not yet accepted the position, according to the Miami Herald. 

The Miami schools superintendent and former high school physics teacher was named National Superintendent of the Year in 2014 and is considered a top educator in the U.S. 

Carvalho has had a successful career in Miami, but he would have to learn how manage a a district with nearly three times as many students in New York City, said CUNY education professor David Bloomfield. "It's going to be a steep learning curve for the new chancellor who spent his entire career in Miami-Dade," he said.

Carmen Fariña is announced her retirement in December after four years as New York City schools chancellor. 

Mayor de Blasio has not said when Carvalho will start, but in a statement called him a "world-class educator with an unmatched track record of success."

"I look forward to welcoming our new chancellor to New York City in the days ahead," the statement said.

The Miami-Dade School Board has planned an "emergency board meeting" for Thursday at 10 a.m. to discuss the district's leadership.
