The official student to teacher ratio in bilingual schools is 1:7; that is, 7 English speaking students to 7 Spanish speaking students. Though a number of teachers in these schools teach English classes, the vast majority of their time is spent teaching their students Spanish. For the learners, they are already fluent in Spanish, so the focus is on listening, speaking, reading, and writing. Spanish speakers in the classroom who want to improve their English often read and write in English.
