That's horrible.
I'm not surprised, though. I had the same sort of trouble with my kid.
Luckily he knew how to read (way above age level, actually) by then, but
the school wasn't really interested in meeting his needs.
One of the many things I feel guilty about, in my parenting, is that I
didn't bring a lawyer to the IEP meetings. I didn't know how to find one
qualified in that area, but, you know, I'm not a non-English-speaking mom;
I'm an academic and supposedly I know how to find things out. I gave up
on his education, basically, same as the school did. Eventually I found a
very small progressive private high school (basically one really dedicated
teacher) for him, which he loved, and which the school district should
have paid for but didn't.
To be fair, really doing the job that schools are required to do in
establishing IEPs for special needs kids is really hard and really
expensive. When we were at LS, they were paying to send one kid to a
private special-needs school in CT someplace, not just for the school but
for the school-bus-certified driver to take the kid there and back every
day. Luckily they were, at least back then and probably still, a rich
district, so having to do that didn't mean no textbooks for the
regular-classroom kids. But I'm sure Sudbury parents do bring lawyers to
the IEP meetings.
