Anyone familiar with the Stanford 10 for 3rd grade and particularly the Word Study section? I'm wondering what these scores might indicate:
1st Grade:
Word Study - 91
Word Reading - 96
Sentence Reading - 95
Reading Comprehension - 93
2nd Grade:
Word Study - 81
Reading Vocabulary - 97
Reading Comprehension - 98
3rd Grade:
Word Study - 49 (!)
Reading Vocabulary - 97
Reading Comprehension - 94
At the beginning of the year, her teacher sent a letter out saying that because they'd been persistently perplexed by the 3rd graders' low word study scores, they were trying something new this year for spelling instruction, but obviously it didn't work for DD.

I'm at a loss. Anyone have any theories?
DD doesn't do as well in group testing situations, but a 49 seems really low.
