Public schools

 Chalkbeat - More than 4,000 students once crowded DuSable High School, then an all-Black academic powerhouse on Chicago’s South Side. Its three-story Art Deco building drew students with a full lineup of honors classes, a nationally known music program, and standout sports teams.

Nat King Cole played the piano in his classroom as a DuSable student. Harold Washington, Chicago’s first Black mayor, studied there. On Friday nights, teenagers zipped through its hallways on roller skates and danced in the gymnasium.

But at the turn of the millennium, enrollment plunged as Chicago closed a massive public housing complex nearby and a growing number of Black families left the city. Amid a national infatuation with smaller high schools 20 years ago, Chicago Public Schools conducted a grant-funded experiment to chop DuSable into three separate schools sharing a campus. What remains today, after that grant money ran out, is an enormous building and, inside, two tiny schools clinging to life.

One has about 115 students and claims the north corridors. The other, with only 70 students, takes the south wings. The inoperable pool is off-limits.
