Are you looking to further test or IQ test to potentially qualify for DYS or are you looking to use IQ scores to better advocate for her in school. If it is the second, I think the Explore results can be useful in that regard. Are you aware if the new school is familiar with Explore? I would start with explaining to them why you took the Explore and what the results indicate. The report that comes along with the results should be useful to them in understanding her level (ie where you DD is with respect to 8th graders that took the test in the fall) and the information on the back seems useful in determining what the student could learn to show growth – you could ask if she can be put at a level that would expose her to material that would lead to growth.
