Shelve it, Kriston.
Ds-then-5 took the WIAT, so I find the WJ talk interesting! I really don't know anything about the various tests.
I can say that on the WIAT, we didn't get a "language composite" score -- our tester said that since 5yos weren't expected to be reading, they didn't typically give them the Reading Comprehension subtest. Ds did take it (I'm guessing she did it out-of-level, just to see?) and scored well, but he didn't get a percentile rank or a standard score -- just the raw score, age equivalent and GE. I was disappointed.
Anyway, we just have a Mathematics Composite, no Language composite. Something to keep in mind for those with big young readers -- I'm now realizing that had our tester not been flexible, he may not have been able to take the Reading Comprehension test at all.
I didn't realize how much the subtests changed with age ... learn something new every day!
