I have had the same 23 students for the past 3 weeks since I received my roster, which is interesting all in itself. Normally it changes a bit in even just a few weeks. These kids must be velcroed to me or something. If it stays the same for Open House two weeks from tomorrow, I'll get a good laugh out of it. Oh, and to answer your question, we receive our lists as early as the mid-July if we come to the school to pick it up.
