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.
