I agree with Cricket2. The scores you will get show that your kid is ready for more work than the grade they are in. That is about it. And that is good enough for me. But it seems to me the scores are not necessarily reflecting the whole truth but rather a glimpse of your child's HIGH points. Usually subjects are way broader than what they get to do on the test and acceleration to the grade level WJ reveal would not work. I am not putting my kid in 4th grade for sure...:-)
