"Again, this is MY opinion and not meant to be offensive to anyone who has a different one."
I always forget this disclaimer, but ditto for my posts.

My daughter solidly met all level four milestones to six years. She also *had* the WISC-III full scale of 99.7 and one WIAT sub-test of >99.9, both at 7 years, but does not perform even near that level any longer. She has had a good, but not perfectly tailored education, has non-accommodated receptive and expressive language LDs and is more strongly motivated to fit in with her peer group than to delve into academics beyond her teacher�s expectations.

I guess this is an example of how these level can be rather fluid and why I believe that early identification (whether by Ruf level or IQ) is imperative to best ensure children meet their own highest level of potential.
