I registered to do MAP testing for DD this spring (we homeschool). I'm just wondering if any of you have found the data to be useful (or not) either with advocating at school or in planning homeschool curricula.

Does it give an accurate assessment of what level of material you should be teaching your child? Or is it more like the WJ-III, WIAT-II, etc... for which you have to take the grade levels with a huge grain of salt?
