Massachusetts recently began requiring bilingual-education teachers to pass English-fluency tests to keep their jobs. Teachers who have flunked the test are taking drastic action to address their obvious educational inadequacies -- they are suing their local school districts.

In Lowell, Mass., four Cambodian-born teachers who flunked have sued on grounds of discrimination. Failing teachers in other Massachusetts cities are consulting their lawyers, too. How they are doing this is not clear. Maybe they have interpreters.

Critics of bilingual education have long contended that rather than -- as advertised -- a way to ease immigrants into instruction in English, it constitutes an educational ghetto where students are taught in their native tongues and are kept from learning in English. The fluency debacle in Massachusetts is a stark demonstration of this critique.

In Somerville, Mass., the five bilingual teachers who took the test failed. In Lowell, 22 of 25 teachers failed. In Lawrence, 27 out of 31 teachers failed. The widespread failure to pass the test is a sign that bilingual education is a misnomer. It is really monolingual education, in any language but English.

Last November, Massachusetts approved a ballot referendum ditching bilingual education for immigrant children and moving to an English-immersion program instead. The referendum was the brainchild of entrepreneur Ron Unz, who sponsored a similar, successful initiative in California in 1998.

Unz believes that teaching children in English is the best way to teach them English. For most people, this is just common sense. But it is too much to expect a state education department to respect common sense or look after the educational interests of its students, especially if it requires confronting a politically correct interest group. Bilingual education is a favorite cause of left-wing ethnic lobbies that think English-only instruction is practically cultural imperialism -- never mind that it gives immigrant kids the tools to succeed in the United States.

So, Unz went to California voters. They passed an initiative in 1998 moving from bilingual to English-immersion instruction by a 2-to-1 margin. Every year since, the performance of Latino students in English-only classes has improved and outpaced that of students in holdover bilingual classes. Unz assumed all of this would provide the momentum to vanquish bilingual ed across the country. "I thought we could have this successful experiment in California," says Unz, "and it would roll on from there." Continued...
