Notices will be sent home in German, and some will be long! If you do not know German, you will need to learn, fast. This is not impossible—I took great classes at the local Volkshochschule, or you can take classes through military bases. On the first day, I had no idea what the notices hanging on the door said, no idea what all the leaflets coming home said; even using google translate gave me such a headache when it came to page after page of materials to wade through. After a year and a half, however, I can skim most school materials that come home and get the gist of it.
