Gifted Issues Discussion homepage Forums Identification, Testing & Assessment WJ-III Problems?

Has anyone encountered scoring errors in a WJ-III parent report? The report in question is the Woodcock-Johnson Normative Update Tests of Achievement, Form B.

DS was scored both in comparison to others in his grade and others the same age. In all scores, his percentile rank was higher by age than by grade except for one--which doesn't make sense to me. I suspect some sort of software glitch, because for the same score (99th%), the program checked the box for "average to advanced" instead of "advanced" or "very advanced."

Now I'm concerned that none of the scores are accurate. Has anyone else run into this before?

I am also curious about the answer to this, although it was already explained to me. I still don't get it all the way, but I believe I was told that things a weighted differently and to just trust the test!

Sorry, no raw score data, but here are the percentiles we did get:

Compared to grade level:
Broad Reading 96 (very advanced)
Broad Math 99.8 (very advanced)
Math Calculation Skills 99 (advanced)
Letter-Word Identification 99 (very advanced)
Reading Fluency 96 (advanced)
Calculation 98 (very advanced)
Math Fluency 99 (average to advanced)
Passage Comprehension 93 (very advanced)
Applied Problems 99.9 (very advanced)

Compared to age:
Broad Reading 99 (very advanced)
Broad Math >99.9 (very advanced)
Math Calculation Skills 99 (very advanced)
Letter-Word Identification >99.9 (very advanced)
Reading Fluency 99 (advanced)
Calculation 99 (very advanced)
Math Fluency 96 (average to advanced) <-- this is the oddball
Passage Comprehension 99 (very advanced)
Applied Problems 99.9 (very advanced)

DS took the test at 5 1/2. Don't get me wrong--we love his scores! But if one is off due to a glitch, couldn't all of them be wrong?

My guess is that at that young age, there is just a fluke in the norms surrounding math fluency. I wouldn't make anything of it, and would say that you just have a really smart kid. :-)

This probably doesn't help, but I do remember when DS was given the WJ-III at age 5 (2 years ago), they didn't have norming data for 5yos, so the plugged him into the 6yo data.
