Here's my question: I'm inclined to downplay my personal impressions of our son so that the tester has no preconceived expectations. Should we or should we gush about how great we think he is? I don't want to set up false expectations but I don't want to sell him short either.
I'll second aeh's advice, and would add that I'd think of this in matter-of-fact terms, not think of it as "gushing". Note - I'm about to use a silly analogy not based on your comments or on any real life situation - so it's nothing personal, just trying to illustrate a point. There's a different mindset between looking at your child and thinking "my child is so amazing compared to any other child his age because he can read Harry Potter at age 2" and "my child has read Harry Potter independently". You're not looking to share excitement over how amazing your child is, but you *are* looking to share factual information about abilities... for all the reasons aeh stated.
Even though they aren't equivalent situations, you might think of it as you would think of having your child try out for competitive sport at a new club where no one is familiar with his abilities (this would be for a child slightly older lol!). For instance, one of my children is an accomplished athlete who's garnered some fairly impressive awards. If we were to move to another state where no one knows her, and I was introducing her to a new club where she was starting fresh, if I go in, as the parent, "gushing" about the awards my child has won, the coaches are going to be hearing *me* the loudest, as opposed to objectively meeting a new athlete. If instead she is introduced as an athlete performing at the "x" level that she's at, then the new coaches evaluating where to place her are going to be looking at *her*. I hope that makes sense. And please know, I didn't meant to imply you'd go in actually over-gushing or anything, just felt that from the way you'd phrased it you're thinking of describing abilities as gushing. As long as you keep it factual, it's just reporting. Again, hope that makes sense!
