Hi, I am new to this board, and I'm hoping you experienced parents could share some advice with me.
My DD5 was recently tested independently and the results came back in the (barely) HG range. She starts K this fall and will be going half day. I signed her up for half day since this is my last year getting to spend so much day time with her and I figured I could do enrichment at home better than they can at school.

This is a Catholic school, which is an improvement over our public (non-charter) schools.
I am wondering how I should approach the school for accommodations for DD. What should I ask them to do in the best and minimum cases? Should I ask them before school starts, or should I let the teacher get to know her first and ask after a couple of weeks of school?
DD is reading at a 3rd grade level and does 1.5 grade math (as near as I can tell). She has been going to preschool so she has decent "doing school" skills, but she is very reserved and sensitive. Do you think she is close enough in skill level that she doesn't really need much accommodation other than choosing her own books for reading?
I spoke with the teacher about reading briefly, but my DD was there so I didn't go into detail. She says they do ability grouping for reading, but I am under the impression that they have just 2 groups: reading and not reading. I didn't ask about math since I hadn't realized yet how little math they actually do in K. (Seriously, they expect kids to come in only counting to 20???)
I'm very worried since I so want her first year at school to be fun and a good experience. I was so bored in school and as a result spent my life underachieving. I want more for her.
Thanks in advance!
Dawn
