eta: (prefaced with the note that both of my dds are gifted to some degree, so in that superior-very superior range on IQ tests) anecdotally, dd#1 works on average 4-12 grades above level in her areas of strength depending on the year and how high the achievement tests she takes go each year and btwn 2-4 grades above level in her weaker area (math). Dd#2 is such an erratic human being, that it is hard to say where she is working from day to day.
Thanks for answering. My dd, though young, recently tested in the superior range and is working 2 grades above. Apparently that doesn't make sense in terms of that chart, huh? It's hard for charts to really take into account every aspect of a child, I guess.
