WASHINGTON (AP) - A report to be released today by the Education Department raises questions about whether students of all races are disciplined evenhandedly in America's schools.
An early snapshot of the report says that more than 70 percent of students involved in school-related arrests or cases referred to law enforcement are Hispanic or African-American. It also finds that black students are more than three times more likely than their white peers to be suspended or expelled.
Education Secretary Arne Duncan tells reporters it's a "sad fact" that minority students across America face much harsher discipline than non-minorities, even within the same school.
The report was based on 2009-2010 data.
