Posting back that despite what I thought was a lukewarm chat previously, we did get some ok testing results for dd4 and I asked the school director about if she would like to have that info.
She said yes, and that she is looking into something called a "developmental placement", which sounds like a way to move a child up due to developmental need (or presumably leave them at the same level if they are not ready to move up). This has something to do with their teacher-student ratios being in balance, I really don't get it all yet, but I was very pleased to hear she wasn't completely blowing me off.
She said the best thing I could do is try to get a statement from the tester as to their recommendation for placement, so I will see what they are able to do in that regard.
