The UW-Madison Arabic, Persian, and Turkish Language Immersion Institute (APTLII) is a residential summer language immersion program for undergraduates, graduate students, and professionals. Courses are offered for academic credit at the beginner, intermediate, and advanced levels (depending on sufficient enrollment). Students commit to using their target language as their only means of communication for the entire summer – in class, in their shared living space on campus, at meals, and at co-curricular activities that combine to create a language immersion experience.
