K.S.
I would highly recommend Covenant Christian Academy off Cheek Sparger near Brown Trail. Tuition is alot, but not so much when you start comparing to others in the area.
For 4th grade, you could be looking at 8-10K per year...
Feel free to email if you would like more information, as my son is in his first year there, as a Kindergartner.
You just can't beat the academics!!
