If you live in the area in Mount Pleasant that is zoned for Cario Middle, your children can attend there. I would suggest that you visit the Charleston County School site that I have referenced which should give you the ability to see what schoold certain neighborhoods are zoned for. Do not hesitate to contact me if I can be of further assistance!

You should really contact Charleston County School to get the straight answer because their policies change from year to year and from zone to zone. I live in McClellanville, which shares a district with most of Awendaw, and last I heard you had to be "released" from your local school's principal and some are more inclined than others. There is a new charter school starting in August of 2012 in McClellanville (see attached link) that my son will be attending. It is K5-5th Grade and will increase a grade each year. The charter school will have an environmental education theme but will be held to the same standards as other public schools.
