'very superior' means at least 2 standard deviations above average (score at least 130 on a scale with mean 100, standard deviation 15). It also means top (approx) 2.5%

which is usually what it takes to be classified "gifted".

Those scores are not scattered at all. They are very even, compared to most examples you see here.

I'm sure your DD can handle a 1 grade skip academically.
