It's a well-documented and disturbing fact: African-American students are suspended from school at disproportionately higher rates than are their white peers.
And even though the overall suspension numbers have dropped in recent years, the racial disparities in school discipline continue to grow.
That troubling trend deserves more attention. Research shows that suspension does not reduce behavior problems or improve school safety.
Rather, kicking so many kids out of class can have harmful effects on the school environment and on the students themselves.
During a recent meeting, St. Paul school board members expressed frustration over the district's disproportionately high rates of black-student suspensions.
Though they make up about 30 percent of the district's enrollment, about 15 percent of all black students were suspended at least once last year, compared with 3 percent of white students.
And while suspension rates dropped steadily between 2006 and June 2010, they went up again during the past school year.
Anoka-Hennepin, Minneapolis other Minnesota districts and schools around the nation are struggling with the same issue.
