Happily, gratefully I can add my own wonderful teacher(s) story here. DS9 has three main teachers in fifth grade after a disastrous 4th grade year. These three teachers get him as a person and as a student and have all worked on making sure he is challenged as often as possible. I have thanked them over and over and I haven't mentioned it to the principal yet but it is on my to do list now. They even love it when he corrects them in class - last year's teacher took it as disrespect.
