Mine doesn't complain of boredom either - last term was the first time I have seen him sucking his thumb since infancy though and his tantrums are worse and more frequent now than when he was a preschooler.

The age/grade equivalent thing is tricky though as it tends to indicate how well a child of that grade would do in the test your child did rather than how well your child would do in the advanced grade (when ds6 did his testing some of his grade equivalents were post high school). If your child has had out of level testing that is different though (and great because it doesn't seem to be that common).

My sympathies with the principal being sent to another school (the initial post made me think it was your child who had been sent to another school - hence some of the confusion). I know how insanely annoying it can be to think you have everything sorted and then have something like that happen. Is there any chance you can find her and get advice?
