I think I talked to you about this once in what we did, but I'll remind you. We basically stuck with the theory that we were asked not to discuss it. Basically, we taught DC the shoulder shrug and the "because the prinicipal told me to" answer which has worked awesome. If they persist, shoulder shrug and change the subject. As for the parents, same thing, you can reply with, it was just necessary, or simply state, we were asked not to discuss it. Put it back on the school. Soon, other parents who were chatting with each other to get the scoop, all had the same reply, "she's not discussing it" and the questions stopped. Now the only questions we get are "How's it going?" and that is fine with me. No one needs to know that it was based on testing, or that we pursued it or the school pursued it or whatever. Come up with a generic reply and stick to it. Before you know it, it will all be old news and they will all have the same answer and there will be nothing to talk about
