A lawsuit scheduled Friday for federal court will determine whether the District can close 15 public schools.

The case argues that D.C. Public Schools’ plan to close 13 schools in June and two more a year later disproportionately affects minorities, students with disabilities and students from low-income families, therefore violating D.C. and federal laws preventing discrimination. The suit was filed by three parents of children whose schools are slated to close — including two parents of children receiving special education services — and two Advisory Neighborhood commissioners who represent neighborhoods containing schools slated to close.
