Below are my DD's results from the WJ-III Achievement tests - scores are the National Percentile Rank:

Total Achievement 98
Broad Reading 94
Broad Math 99
Broad Written Language 97
Academic Skills 98
Academic Applications 92
Academic Fluency 98
Math Calc. Skills 99.8
Written Expression 96
Letter-Word Identification 96
Reading Fluency 93
Calculation 99
Math Fluency 99
Spelling 96
Writing Fluency 94
Passage Comprehension 73
Applied Problems 93
Writing Samples 88

All were Advanced scores except for Passage Conprehension = Average. Academic Skills, Letter-Word Identification, and Spelling were Very Advanced.

My question are - is there a chart that will put these scores into grade quilivencies?

The 99.8 in Math Calc. Skills was only Advanced not Very Advanced?

I've searched but can't find these answers. Thank you.
