Argument: English-only in schools disadvantages non-native students
In the 1974 case of Lau v. Nichols, the Supreme Court ruled that: "there is no equality of treatment merely by providing students with the same facilities, textbooks, teachers, and curriculum; for students who do not understand English are effectively foreclosed from any meaningful education" (U.S. Supreme Court, 414 U.S. 563)
"Congress Should Prioritize English Learning, Not English-only." MALDEF on Opposing Views.com: "For ELL students in grades K-12, two-thirds of whom are native-born U.S. citizens, poor instruction denies them the tools to gain the language skills necessary to participate fully in the American economy and society. There is ample evidence of the challenges these students face: Since 1975, at least 24 successful education discrimination cases have been brought on behalf of ELL students in 15 states. [...] With limited opportunities to learn English, ELL students face particularly poor outcomes. The progress of these students is marked by failing graduation tests and high school drop out rates that are higher than classmates who are fluent in English."
Kathleen McDade. Should English Be the Official Language of the United States of America?Associated Content. January 18th, 2008: "Not a bad idea. If immigrants can learn English, they can get better education and better jobs, and be more productive members of society. The problem is that while English-only legislation does aim to encourage (or force) people to learn English, it generally doesn't include any provision for the ESL classes that will teach people the language. That's unfair - and it also makes me wonder whether the point is not to make people learn to speak English, but to make the non-English-speaking people go away."
