Have you considered taking a school tour and asking what the breakdown is at the school your dd will be attending? If you're in an area that has charter schools etc, you may find that the end-of-K reading level expectations are different at different schools. Another thing you might could try is googling DRA level by grade or something like that - our kids' elementary school had a scale that related DRA level to grade level (beginning and end of year).
I also would try not to get too worried about reading level at this point - there probably are going to be kids on a huge spectrum of reading skills going into K with your dd. I'd be more interested in learning about the full day - what's taught, how it's taught etc. Reading groups and math lessons were only a very small part of the day at our kids' elementary in K-2 - the larger part of their curriculum was spent in project (group) work, writing, and going back and forth between never-ending pullouts
