The U.S. Supreme Court hears oral argument in the case of Parents Involved in Community Schools v. Seattle School District No. 1. The Seattle School Board adopted a plan to assign students to schools on the basis of race in an effort to overcome the effects of segregated housing patterns. Parents of children who were not assigned to the school they chose sued, questioning the validity of the desegregation plan. Court will decide what role race can be used when assigning students to K-12 schools in an effort to achieve diversity.
