If you would possibly relocate - one of the best schools is in Irving (Las Colinas area). It is called North Hills School (Charter) it is Nationally Ranked and is more like a college preparatory school going from young ages through high school. It is very ethnically diverse with lots of activities. I have a niece who goes there and if my children were school age that is where I would send them. There is a waiting list so don't delay if you are interested. Because it is Charter school the expenses are not like a private school.
