LOS ANGELES (AP) — The American Civil Liberties Union says the state of California is failing to educate students who need to learn English.

In a case scheduled for trial Tuesday, the ACLU claims that the state's own data show about a quarter of school districts don't provide needed language instruction to students who don't speak English.

The state says the ACLU relied on a survey of school districts that doesn't provide an accurate picture of how English learners are being schooled statewide.

The ACLU wants the state to make sure all schools comply with requirements and educate 20,000 neglected non-English speakers. The U.S. Department of Justice has filed court papers supporting the ACLU's case.

The trial in Los Angeles Superior Court won't include testimony and is only expected to last a day.
