A high-level panel commissioned by Mayor Bill de Blasio called on the city to adopt a sweeping measure to address entrenched segregation in education: create diversity targets for all 1,800 schools so that their population reflects the racial and economic makeup of the surrounding areas. Over the next five years, the panel recommended, elementary and middle schools should reflect the racial makeup of their local school district, and high schools should look as much like their local borough as possible, in terms of race, income level, disability and proficiency in English.
