I try to put myself in teachers' shoes and figure out where they are coming from. A lot of the time I see that it's just that they can't handle extra work or complexity, which I get. But this is the kind of stuff I don't get. Why would she care? What is the fear? As I say to my DD: what is your main concern?

Does your DS have a history of poor performance on reading evaluations in some fashion? Is she worried that other people will ask for things like this? Is she just a very rigid and rule-minded individual? Is she mad at you for other reasons and just feeling pissy?
