Immersion schools are educational institutions where students are taught in a language that is not their native tongue. The goal is to help students become fluent in this second language while also learning standard subjects like math and science. This approach often involves teaching all or most subjects in the target language, creating an environment where students are surrounded by the new language. These schools can focus on various languages, such as Spanish, French, or Mandarin. Immersion programs are designed for students of all ages, from preschool to high school, and aim to promote bilingualism and cultural understanding among students.
