NEW YORK (CBSNewYork) — City Hall has made its pick to replace retiring schools chancellor Carmen Fariña.

Mayor Bill de Blasio said that Alberto Carvalho, the superintendent of Miami-Dade County Public Schools, will be the next head of the city’s Department of Education.

De Blasio called Carvalho a “world-class educator with an unmatched track record of success.”

“I am very confident that our extensive, national search has found New York City the best person to lead the nation’s largest school system into the future,” the mayor tweeted.

Carvalho replaces Fariña, a New York City educator for more than 50 years. She’s been a teacher, a principal, a superintendent, and of course, a schools chancellor who improved test scores and graduation rates. She also brought pre-K and 3K to tens of thousands of city kids.

Fariña told CBS2’s Kramer she’s looking forward to retirement with plans to take a safari with one of her grandchildren, to take art and history courses, and to continue a life of learning.

Miami is the nation’s fourth largest public school system, with New York being the largest.

The DOE says the mayor is travelling to Florida to make the official announcement.
