On March 15, 2016, North Carolina published its Report to the North Carolina General Assembly: Consolidated Data Report 2014-15 (Rep.), providing information on, among other things, discipline rates among the states racial/ethnic groups. Table S3 (at page 29) showed that between the 2010-2011 and 2014-15 school years, the black short-term suspension rate declined from 3.86% to 3.0%, while the white rate declined from the 0.98% to 0.71%. Thus, the ratio of the black rate to the white rate increased from 3.94 to 4.23. Similar increases in the relative difference between black and white rates were shown for long-term suspensions and expulsions, though these outcomes were rather rare.
This information came to my attention as a result of a 2016 presentation by the Public School Forum of Norther Carolina, which also presented Table S3 from the General Assembly report, which formed the basis for the statement that “Black students in particular are as much as four-times as likely to receive short-term suspensions as their white counterparts.” The presentation later states: “Restorative Justice programs like those in Oakland Unified School District have proven to be effective in decreasing the overall incidence of student misbehavior as well as reducing racial gaps,” relaying on Restorative Justice in Oakland Public Schools Implementation and Impacts (Rep.). (2014, September).” See the Oakland (CA) Disparities,page regarding the way that study has led many observers to believe that the ratio of the black suspension rate to the white suspension rate decreased in Oakland, though it in fact increased.
