Well, interestingly enough, I have virtually no standardized test data on her at all other than her IQ test, where she did appear to kind of be a bust on one section (but maybe she just wasn't good at that skill), so I don't really know how she handles testing generally. However, she recently took another high-stakes state test which she was HUGELY anxious about because the school made a HUGE deal about it and so, blammo, test anxiety is ours! They made no fuss at all about this one for whatever reason. Weird. Anyway, I know she cares about performance. She has been asking and asking about her scores on the high-stakes test.
