From the Seattle Times:

Race dramatically skews discipline, even in elementary school Originally published June 23, 2015

The racial gap starts as young as age 5, and it’s persistent enough that civil-rights investigators are taking note.

Judging by the numbers, black students in Seattle appear to cause four times more trouble than their white classmates, because that’s the rate at which they get suspended from school.

More than 800 black students were sent home last year, many missing weeks of instruction for comparatively low-level offenses like “disruptive conduct” or “disobedience” or “rule-breaking.” At some schools such as Seattle’s Washington Middle — where, despite comparable populations, 94 African-American kids were disciplined and just seven whites — the data is so lopsided that confrontation with uncomfortable questions becomes difficult to avoid.

As striking as the racial split is the age at which it begins: kindergarten.
