To be accepted into an American school, you will need to take a couple of tests. Which tests you have to take depend on your academic background. If you are moving to the United States as a ‘Freshman’, you will most likely have to take both the SAT as well as the TOEFL. The SAT tests both your English and Math, while the TOEFL tests your knowledge in English, more specifically your reading, speaking, listening and writing.
If you are ‘Transfer Student’ or ‘Graduate Student’, you will probably only have to take the TOEFL, which tests your reading, speaking listening and writing. The TOEFL can be made on set dates and locations in the Netherlands.
