 Dual language programs use the partner language for at least half of the instructional day in the elementary years.Dual language programs generally start in kindergarten or the first grade and extend for at least five years, but many continue into middle school and high school.The programs aim for bilingualism, the ability to speak fluently in two languages; biliteracy, the ability to read and write in two languages; academic achievement equal to that of students in non-dual language programs; and cross-cultural competence.
