The report, based on federal government data from 2015-16, also found that racial disparities in suspensions remain an acute problem. Nationwide, African-American students lost five times as many days as white students.

New state data shows 46 percent drop in school suspensions over the last five years. The suspension rate for African American students in 2016-17 was 9.8 percent, for Latino students 3.7 percent, for white students 3.2 percent, and for Asian students 1.1 percent.
