Don't worry about the terminology - it's just words and there's very little consensus on their meaning anyway (though round here, specifically, people usually mean IQ over 130 when they say gifted, roughly). You and the school need to look at your daughter more than the numbers - but I don't mean by that, don't test. If the school wants to do a WISCIV and will arrange it out probably means they'd be happier having a report from it. There's not much downside - most children enjoy the testing.
One reason for wanting the results is that if your DD's results are very high, this may make it easier for everyone to know she needs challenge. Going through school doing well without much effort is not benign - it can lead to perfectionism and stop children learning to deal with things that are hard for them.
