Seems decent? You do realize that only a subset of the general student population takes this exam, so it’s a bit skewed, don’t you?
Frankly, retaking the SSAT because you “only” have a 95th percentile is a waste of time. The phrase “point of diminishing returns” come to mind.
Your household’s time could be much better spent on honing essays and supplemental materials (if warranted). I’m not sure what the AOs are looking for in the parenting statements, but I suspect hints of red flags are one item. For the student essays, it is very important that they are in the child’s voice. (A couple of years ago there was a poster who discovered that their parent had replaced one of their essays on multiple applications because the parent thought the kid’s essay wasn’t impressive enough. The only school the kid got into was the one where the parent hadn’t done the switcheroo because the parent didn’t want the kid to go to such a lowly place.)
