This thread should actually be in the Fort Worth forum, not the Dallas one.
But there are several good Christian schools in Tarrant County. Fort Worth Christian in North Richland Hills is great (
Fort Worth Christian - Welcome), as is Harvest Christian Academy in Watauga (
Harvest Christian Academy WebSite).
If you're looking for private schools in general, Trinity Valley (
Browser Not Supported) and Country Day (
Please wait...) are excellent schools in southwestern Fort Worth.
I honestly don't know much about Calvary Christian in north Fort Worth, but maybe this website will have info:

Hope it helps!
