I'm surprised how many are saying their kids didn't read until 1st. All kids is our K (catholic school) were reading by the end of the year.
I'm not terribly surprised. Different kids take off in different areas at different times. The OP said her son is very advanced in math/science IIRC. I would imagine it is not too unusual to learn unevenly, showing great interest in one subject and catching up in a different area later. E.g., although my son was an early reader, he really didn't take off in math until he started school.
Also, the OP's son is just 5yo going into first, and that is the usual age many kids really start to read.
Of course, different definitions of "reading" will also make a difference. I imagine that in a GT 1st grade classroom, there will very advanced readers who can read HP, and beginning readers who are just learning Bob books. I also agree with a previous poster who said it depends on your region. There are probably some neighborhoods in the Twin Cities where you will find the majority of kids reading by 1st.
Mom2_3: I hope you do keep us posted to let us know what types of readers are in the class! And I do repeat my recommendation to email the teacher to see if she shares any of your concern. He/she can either eliminate your worries or give some good tips.
