Students who are black or poor are suspended at much higher rates than those who are white or affluent, according to a new study of school discipline trends in Louisiana. Even in specific fights that involve one black student and one white student, the black student typically receives a slightly more severe penalty.

The study and accompanying policy brief, both published by Tulane University’s Education Research Alliance for New Orleans, examined data from over 1 million disciplinary incidents logged between the 2000–01 and 2013–14 school years. It contributes to the growing body of research suggesting that intentional or inadvertent biases result in harsher punishments for minority children.

On average, black students were twice as likely as whites to be suspended for a behavioral infraction over the course of a school year, while low-income students were suspended about 1.75 times as often as more affluent ones.
