If the first signs of ADD/HD are from the teacher, I suggest there is a critical lack of attentive parenting, and surely a lack of discipline-- 2 critical factors, yet you point finger at everyone else first with no reservation. A parent's first line of response should be a request for the school psychologist to do an observation of the child in-class. Then the parent could come in to observe and then "compare notes" to determine why, if there are any differences. In this, the teacher's behavioral management would also be considered. Very few parents are "trusty" at all these days, especially when there are those who are so willing to indict the entire line of staff with prejudice.

Sure there are exceptions, but for many parents, the first sign of ADD/ADHD are the complaints from the teacher. At this point, I think parents should spend a day or two following the kid from class to class and determine if their kid needs medication or the teacher is deserving of a pink slip. If the teacher has no leadership and commands no authority in the class, the teacher complains, the principal is lazy to investigate, parents are too trusty, and the kid gets put on the meds.
