The few people we discussed testing with (when DD was 4-6yo) wanted us to NOT be present in the room.

That meant no testing-- as an absolute thing, actually-- because of her (relative) medical fragility. Line of sight was a critical make-or-break factor for us, although we completely understood why policy had parents deprived of that during testing.

Catch-22 for us personally.

I'm surprised that so many parents were present with children this age. Not judging-- just surprised, since our sample indicated that this would be rather uncommon. Might be a regional/local thing.
