The Discipline Disparities Research-to-Practice Collaborative released several resources concerning discipline policies in public schools. The Collaborative produced the resources in response to its findings that students with disabilities are suspended at disproportionately high rates – almost twice as frequently as their peers who do not have disabilities and for longer periods of time. The intersection of race and disability results in even larger disparities. Twenty-five percent of African American students with disabilities were suspended in 2009-10 compared to nine percent of white students with disabilities. The Collaborative reported that during the 2009-10 school year, more than 3 million students in grades K-12 were suspended. The Collaborative is comprised of 26 nationally recognized experts from the social science, education, and legal fields.
