Does it cost more to implement a two-way bilingual immersion pro

"Does it cost more to implement a two-way bilingual immersion program?

Not necessarily. However, many successful programs have found that some extra funding is necessary to provide staff development and purchase materials in the target language, especially for library and research materials."

As far as I know, the funding for public schools are primarily from local real estate tax. Federal and state governments provide some, generally speaking, not specific to the bilingual immesion programs. 

I think it is a good cause and it is worth it to pay a little more tax, if it is so, to provide better educations for children, no matter what ethnic groups or races they are for.  It is good both for humanity, and for the society, in the long term.  That is my opinion. People can disagree.  That is the purpose of propositions. You vote for or against them.
