@arda Do you mean high schools in the English sense, i.e. grades 5–12 and ages 10–18 (i.e. Gymnasium etc. in Germany), or German Hochschulen, i.e. colleges and universities? Btw., you may also be interested in expatriates.stackexchange.com/questions/tagged/germany and academia.stackexchange.com/questions/45751/…

Gymnasium

@arda There are several bilingual German/English Gymnasiums, some of them are called “Europa-Gymnasium”. As far as I know, it differs from school to school (and state to state) how many and which classes are taught in English.

Private schools are not that common in Germany, but there are indeed some that teach in English exclusively, but the only one that I know of is rater new and follows a British curriculum and ends after 10th grade with a degree that is recognized as equivalent to German Mittlere Reife which allows the graduates to pursue Abitur elsewhere.

Thanks
