Thanks for all your input! My powers of Goigle rarely fail me, but it is proving nearly impossible to determine exactly how broad scores are calculated. As others have noted scoring on the WJ III is by computer only, so there are no tables available to view. It's just confusing because with the other broad scores "the whole is greater than the sum of the parts" in a sense, but not the reading cluster.

Polarbear- thanks for the explanation. I wish we could find the exact formula! What are the most useful numbers on the full report? His Broad Reading score of 137 had a grade equivalent of 4.6, Broad Math 139 GE 3.0, and Broad Written 139 and GE 3.3.
Can anyone tell by comparing scores if it was norms for Kindergarten or 1st grade?
Does it matter to DYS if scores are based on grade or age?
I would love to find out it was normed for 1st, which would hopefully result in qualifying scores! Wishful thinking on my part, I know, but a girl can dream can't she?
