I'm not familiar with Case 21 but DD6 also scored 18 matrix reasoning and 12 on digit span. Our ed. pysch. told us her WM is her weak area but still high average (score 120) She scored 15 on letter number sequencing so that brought the number up. When she told us she said, "but you're not surprised right" and it did make sense because DD is much better with math when she can actually see the numbers versus mental math but with practice this has improved. The psych did point out that she wasn't worried about it because this is an area that can be improved and because she also has processing speed in the gifted range. What is your DD's processing speed like? Will the school administer the WJ test or will you do that on your end? It does sound like your principal has an open mind and willing to work with you. Yes, what is the evaluation process for?
