Sounds like a lack of attention to detail permeates the school and its practices.
Its a simple thing to get texts in other languages.
I was told that because the district (or state?) has to approve the textbooks, there was no way they could do this for all of the four languages offered at the immersion school. This is CRAZY to me, because I think that without textbooks in the target language, a school cannot honestly be called an "immersion" school.

However, the dual-language program that we are looking at does provide content-area textbooks in Spanish for all grades. I suppose it's easier to find Spanish-language materials that are consistent with the district/state guidelines (although several administrators told me that this has been one of the biggest challenges that the school has faced). This school has also recently implemented an AR program in Spanish, which the kids are required to complete along with the English one. I really like that this school is doing its best to fully promote biliteracy.
