In terms of these I find that (ii), (iii), and (iv) do seem to fit the term "non-cognitive" in that they're things we build up with experience and practice but don't really think about consciously. But social maturity surprises me, perhaps it's a technical term that means something different than I think, because at least for me maturing took quite a bit of thought. The "overall" score seems kind of mysteriously thrown in.
