I think when you work with a school district who makes it obvious they will only do for your child what has been done for every child who came before them, showing you they don't look at each individual case, it is easy to feel they are always looking to negate your info. From my personal expericence, I try to be optimistic that their methods will work, but at the same time I also feel schools can be good at telling you what you want to hear at the time in hopes you go away. Then when you come back looking for more, they rephrase things or change them all together.

I think the letter your wife wrote was great and to the point. I do think from my experience with the map, with a child who is a perfectionist, that the test is low stress for the child. My dd6 thinks it is fun. I do not think it should be the only method of assessment, but can be a good tool. The results come right away so that is good. I hope it goes well for your son and the school opens their mind to more options.
