 Students do not need to relearn how to read in English since teachers help them transfer their literacy skills from one language to the other.Other 90/10 programs separate students by native language and provide initial literacy instruction in the native language, adding second language literacy by second or third grade.In partial immersion or 50/50 programs, initial literacy instruction is either provided simultaneously in both languages to all students, or students are separated by native language in order to receive initial literacy in his or her native language.
