Explain that your understanding of GT is that these are kids that need placement at their level, just as any child needs work at their level, no matter the level. And you've never heard of this perspective of theirs.
Don't "whine" that the test was given without warning, as that would be criticizing how they do things. Especially if they are a school that believes parents helicopter too much. Instead, remark that had you known prior to the school year that he didn't pass the test, you would have rethought your enrollment choice because you knew he would have trouble in a class that is too easy.
Well, that's what I would do. But I hate confrontation, and I try to go in with the attitude that they want my child to thrive.
MON - so glad that this helped your DD. Awesome!
