Disability rights groups have lined up to defend a California law that prohibits the Law School Admission Council from “flagging” LSAT scores—that is, alerting law schools when test takers received extra time as an accommodation for a disability.

Thirteen state and national advocacy organizations, including the Association on Higher Education and Disability and the National Association of Law Students with Disabilities, on Tuesday filed an amicus brief in a lawsuit filed by the council that is pending before California’s Third District Court of Appeal.
