I'm thinking about studying in Germany next year at a university. I am a US citizen. I have completed a 2 year Associate's degree program at a trade school and also finished my general education requirements, at about 45 units as a combination of AP tests and classes at a community college.
When applying, they the schools ask for an official copy "school-leaving certificate" - I'm guessing this means diploma. Do I need an official copy of my high school transcript and/or diploma? Does my Associate and other college credit infer that I have already successfully completed high school? As I haven't quite mentioned any specific schools, I think this answer is probably the same regardless of the country of the institution.
