By knowing if she is HG, EG or PG, I will have a better understanding on next steps with her education. If I knew her reading level I can get apporiate books that challenge her yet stays within her maturity level.
Keep in mind that test scores provide a single number, from a single moment in time, about a single construct of intelligence. The number is not your child, it's just a big warning to check your assumptions about child development at the door.
A more specific number won't tell you whether the child will passionately pursue reading, or math, or music, or history, or sculpture..... it doesn't tell you what they will love or be good at. It doesn't tell you what kind of school or curriculum will be a good fit. What it does tell you is to pay close attention to where your child leads, and to support and feed whatever they pursue. Find books that engage and challenge her, at a mix of levels, read complex stuff with with her, and make sure there's always lots of options around for her to pick up to read on her own, even ones you don't think she'd like or seem too easy or too hard (FYI, there's tons of book recommendation threads on the forum). I think many of us inadvertently withheld material from our kids - whether books or math or toys or activities - just because it never occurred to us they could really be ready, could really want
that so fast, so soon.
What you do know is that you have an outlier, a pretty significant one. The exact number (which isn't actually all that exact) doesn't help you know what that child is going to need. You already know the key thing: your child is going to learn differently from most around her. Possibly very differently. You don't yet know what her different will look like, but she'll show you. You may have to advocate hard at school - but then again, her passions might turn out to be in areas better supported at home. Don't expect that school won't work, but don't be surprised if you have to try plan B. And C. And D. All a bigger number can tell you is to be that much more prepared to do things differently, in whatever ways she shows you she needs. Good luck. It's a whirlwind!
