If it's any help, two of my children have been through neuropsych evals, and at your dd's age, both thought they were fun
They were tired by the end of the day (ours were given as full 6 hours in one day, with part of the intent being to give the psych a chance to see how they worked when "fresh" in the morning vs at the end of the day). My ds has had a second follow-up eval but he was older, and by that point in time didn't look forward to it as "fun", but also didn't complain much about it either
I don't remember exactly what we told them the first time around, but I do remember getting advice from our actual neuropsych re what to say, and she had a great suggestion that worked really well - so it might be helpful to ask your neuropsych
Best wishes,
