Hi Lydia! Sorry for the late response. A lot going on over here recently. Anyway, yes, this is essentially an expansion of the NNAT, in an attempt to respond to some of the criticisms of that test with regard especially to overlooking verbally-strong learners. Not much of a track record yet in that respect, but the original nonverbal section should be pretty much equivalent to what it has been historically.
