Amazedmom, we used that test a couple of times, as well as their reading and math programs and I can tell you the reading results are pretty accurate. I have a dd who read Hop on Pop style books before 2 and had similar results with your dd on DORA at 3(she is 5 now). We tested her when she turned 4 and she came out not only pg, but way over the DYS threshold, so brace yourself. As my dd says often, they do come as a package with lots of intensity, so the bad news is that yours is not likely to grow out of that either, LOL.
You could work with your dd on reading comprehension. As a young 3, I remember my dd needing more explanation for "inference" questions. Modeling how that works and thinking out loud helped.
We did not like their DOMA test because it was too linear and it would not test advanced skills unless the child mastered the easy ones. My dd, and yours sounds similar, prefers anything abstract; she hated math until she discovered algebra.
