TOEFL certifies your proficiency in Academic English.
Since only some SDA Bocconi Masters require the TOEFL test, we suggest that you check on each Master’s website.
In any case, if you are a native English speaker or you obtained a High School Diploma in English or you hold a degree from a University where courses are taught in English, you won't have to take the TOEFL test.
The School's TOEFL code is 0698.
The test is used and admitted all over the world, and consists of four parts: listening, reading, writing, and speaking.
More information and preparation kits can be found at the official TOEFL website
