No. All research concludes that learning multiple languages does not interfere and “in most cases, learning another language enhances a child’s English ability. Children can learn much about English by learning the structure of other languages. Common vocabulary also helps children learn the meaning of new words in English.” ERIC, Education Resources Information Center

Students from TSA transition into traditional programs just as they would if they came from any preschool because they are taught the same, if not more, content due to a low student to teachers ratio and differentiated instruction. In an immersion classroom, traditional content (math, science, reading, etc.) is taught in the target language (Spanish). Spanish is not the content of instruction, but rather the language of instruction. The children will transfer the content into whatever other language they speak.
