I think (and I could be totally wrong- I'm only peripherally aware of these things) that California just cut out the bi-lingual education, like teaching classes in Spanish and introducing English later.
But, you always need ESL teachers for students who learn English at school whether it be additional tutoring or full-immersion programs.
I'm not sure, but I knew and ESL teacher in California that said she lost her job when ESL was eliminated and was looking to move to Washington state to teach Spanish, but changed her mind when she found out that WA paid $15,000 less than CA and that there were few job openings.
California has lots of evening ESL classes for adults. Kids in regular school get a year of intensive english, and then can pretty much handle regular school. Thats how it is supposed to work. The category that got eliminated was the bilingual teacher where the kids learned half the day in one language and half the day in english. This program did not get kids to use english until high school and maybe not even then. I believe CA has learned that treating kids with TLC in their first language is a recipe for disaster. And teachers need luck and skill to avoid layoffs when the enrollment in the classes they teach is dropping.
