Good for you OHG. This is somewhat confusing and frustrating for you I'm sure. You have great perspective on it. If you are interested in testing, I would encourage you to pursue it if it's an option.
For a couple of reasons.
First, the kids seem to LOVE the testing, they think it's really fun!
Also, it's helped me really put into perspective what my kids need in terms or education.
Even if you aren't planning to do anything differently this year.
Knowing the girls capabilities has helped me provide so many fun and appropriate after school activitites. I'm embarrased to say I wouldn't have thought of doing so otherwise.
Of course, it seems pretty clear you are aware of DGS's capabilities anyhow!
