There are about 20,000 students in California who need to learn English but aren't, according to a lawsuit filed today by the American Civil Liberties Union. Under state and federal laws, schools are required to teach non-English speakers the language, but the ACLU says that some kids are being pulled out of their English classes too soon.
"These kids are not getting the differentiated learning they're supposed to be getting," lawyer Mark Rosenbaum told the Associated Press.

The suit comes after the ACLU filed a smaller lawsuit last year focusing on a school system near Fresno. In that case, the Dinuba Unified School District in Tulare County was accused of using a substandard curriculum in its English classes, the Los Angeles Times reported.
The ACLU accused the school district of focusing too much on complicated grammar and not enough on practical, real-world curriculum.
