OK, I know that I'm going against the tide here, and *PLEASE* don't get upset. But I would LOVE it if this were the biggest problem I had with my children's schools.
Yes, I agree that was a very reassuring response, and this probably reflects a mismatch of what *you* think is important and the school. Or perhaps the message was miscommunicated - I'm sure that a child that turns in a paper with spelling errors will get *some* feedback from the teachers, right? Just because a specific list of spelling words isn't being sent home doesn't *necessarily* mean it isn't being taught in the classroom.
No school is going to be a perfect match for you, and this *is* something that you can easily do a MUCH better job yourself because you have a much better idea of what particular level she needs to work on. A list handed out to the class will probably be the same for all the kids and not take into account where *she* is. Check out the Spelling City. It's a great way to for kids to practice a list of spelling words, and they have at least 3 modes for each list - teach, test, and play word games. You can create you own list of words just for your kid, or you can look up lists registered by schools all around the nation. If her teacher doesn't have a list, find another list from that school, a nearby school, or thousands of 5th grade classes in public and private schools in any state. (Plus, she doesn't have to waste her time writing sentences proving that she understands something she may have learned 2 years ago.)
It's fine to discuss with your school or teachers the things you take issue with, but my *personal* advice is to not make much fuss about the small things that you can fix, so that you have more leverage to make an impact when bigger issues come up, as they inevitably do. You won't have a reputation as being a being a "difficult" parent or complainer, you know what I mean? And 2-3 years down the road, you may need to ask for something big and you'll want them to see you as someone who doesn't complain much.
I'm just sayin'.
