I have had experience with a teacher that would not listen to me too! I too spoke with the principal, which had little to no avail. My situtation was a little different as my son had emotional issues that were affecting him in school, how ever that's no excuse for being ignored. This was second grade last year around the end of March. I ended up taking my son out of that school, and enrolling him in an Independent Studies Program which was offered by our school district. That may or may not be an option for you. You could try and have him place in another 2nd grade class in his school, it's done all the time. You could also request a principal and teacher conference, by law they must agree to that option! You also have the right by law to come and observe your child in his class environment, especially under these circumstances. If you were told something different then you need to contact your school district as soon as possible! We as parents know our children better than anyone, and we don't need to be argued with, we need to be listened to! Some times children and teachers don't mix, and sometimes parents too! It's no bodies fault, just reality! I hope this helps, and I hope school can remain a positive thing for your son.
