The Middle Eastern and Mediterranean Language Institute (MEDLI), formerly known as the Arabic, Persian, and Turkish Language Institute (APTLI), is an eight-week summer intensive language program for undergraduate and graduate students, professionals, and nontraditional students.

Students learn speaking, reading, listening, and writing skills through classroom instruction and a full range of co-curricular activities. Students will receive eight credits and a letter grade (A-F) after completing the program. MEDLI participants must complete both four-week sessions for a total of eight weeks. 

MEDLI is one of the Wisconsin Intensive Summer Language Institutes (WISLI).
