The Supreme Court ruling in Lau v. Nichols in 1974 established that schools must provide appropriate support and instruction for students with limited English proficiency. Another significant ruling is the Plyler v. Doe case in 1982, which declared that states cannot deny free public education to undocumented immigrant children.
