Parents protest test in English

I think I see the problem here,from the article-

"Speaking through a Spanish-English translator, parent Erika Soto said her third-grade daughter is “very smart, but because of this test, she is going to be labeled a failure. So how is she going to feel?’’

Let me pose this question, if I move to a foreign country to find a better life, should I expect the natives to speak my language or should I expect I need to learn theirs?
