Dual language is a form of bilingual education in which students are taught literacy and content in two languages. Dual language programs foster bilingualism, bi-literacy, enhanced awareness of linguistic and cultural diversity, and high levels of academic achievement through instruction in two languages.

Research consistently finds that the immersion experience enhances English-language development. Immersion students who complete a full program perform better than non-immersion students on almost every academic measure available. They are well-read, competent, knowledgeable, interested in world affairs, and have strong academic skills in math, science, social studies and literature. Immersion education is enriching in every area of academic study and will give your child the advantage of becoming multilingual as well.
In addition to reaping the social and economic advantages of multilingualism, immersion learners benefit cognitively, exhibiting greater non-verbal problem-solving abilities and more flexible thinking. It has been suggested that the very processes that learners engage to make sense of a teacher’s instruction also make the learners pay closer attention and think harder. These processes, in turn, appear to have a positive effect on cognitive development.
From the standpoint of academic achievement, three 30-year studies consistently show that immersion students achieve as well as or better than non-immersion peers on English-language standardized tests measuring verbal and mathematics skills. (Source: tcgis.org)
