Mayor Bill de Blasio is promising to push for diversity at our city's elite high schools.

He says 20 percent of the seats at specialized high schools, like Bronx High School of Science will be set aside for economically disadvantaged students starting in September 2019.

Admission there is governed by a test.       

Mayor de Blasio hopes to replace the test with a new admissions process using measures such as middle school class rank, but that would require action by the state legislature.
