According to Carly Sitrin of Politico (the full article is behind a paywall),

Black students in New Jersey were suspended from school last year at more than three times the rate of white students, according to a report from the state Department of Education. The state’s annual report on student discipline — released quietly last Thursday with no accompanying statement from the DOE — shows an 11 percent increase in total in- and out-of-school suspensions for all students from 2017-18 to 2018-19. Black students were suspended at a rate of 8.9 percent, while the suspension rate for white students was 2.7 percent, according to the report. In total, 55,971 New Jersey students received at least one in- or out-of-school suspension in 2018-19, compared to 50,283 in 2017-18. Nearly 1.4 million students attend public schools in the state. The report does not break down the numbers by race.
