I continue to field emails (not a large number...but a sufficient quantity to result in this post) for an explanation why the WJ III cluster standard scores often do not approximate the arithmetic average of the test standard scores that comprise a particular cluster.
I remembered writing about this in 1994 with regard to the WJ-R Broad Cognitive Ability cluster score. So, I scanned those pages into a pdf and they are now available by clicking here.

Thank you! I think I need to just print out the pages and distribute them at IEP meetings so I can stop trying to explain that yeah, the numbers don't "look" right, but they are.
And on an almost-wholly-unrelated topic, may I suggest this shirt

as being almost as necessary as the CHC shirts?
