In Wake County, our schools run K-5, 6-8, and 9-12. I assume, right now, your 10 year old would be in 4th grade. As the father of a 3rd grade daughter, there are children in her class that meet with a literacy specialist at both ends of the spectrum - reading well above grade level, as well as those students who need extra help with reading.
If you'd like to learn more about our school system, the best places to start are: http://www.wcpss.net
and search for "Demographics" or http://www.ncreportcards.org
and find Wake County schools. If you need or want additional help - just ask!
