For the first time in its history, Miami-Dade County Public Schools have received an "A" rating from the state.
Schools Superintendent Alberto Carvalho celebrated the news on Twitter Wednesday, adding that in addition to the rating, there were no "F"-rated traditional schools in the county for the second year in a row.
"The ONLY way a school district can earn an 'A'-rating as @MDCPS has just done for the first time in its history, is through the critically important work of its teachers," Carvalho tweeted.
He was expected to hold a news conference Thursday to discuss the rating. Miami-Dade is the nation's fourth-largest school district with nearly 350,000 students and more than 40,000 employees.
The ratings are released by the Florida Department of Education based on up to 11 components, including student achievement and learning gains on statewide, standardized assessments and high school graduation rate.
Broward County missed an "A" grade by just two percentage points, with 96 percent of its schools earning an "A," "B," or "C" rating. Only one school - North Side Elementary in Fort Lauderdale - earned an "F."
Monroe County Schools also earned an "A" rating from the state.
