I can see why parents might want to withhold this information, but if you are looking at a 504 plan, I think you need to share it so that the school can make appropriate accommodations. One thing you can do is have your DD start and then after she's been there for a few days or a week (and the teacher gets to know her), THEN share the information. That way she/he is not unfairly biased before getting to know her. To be honest, DD's teachers who have known haven't seemed to put much thought into it, but when they did I think it was helpful because then I had an explanation for why she would space out and was slow. Otherwise they probably would have viewed it as a behavior problem. One long-term sub knew about the ADHD but STILL viewed it primarily as a behavior problem and was constantly trying to "fix" her. I can't imagine what the teacher would have been like without the info. Probably a lot worse.
