You can search for schools at each level in Texas through FieldLevel and/or NCSA. See links:

As discussed above, schools are much more spread out in Texas. It takes an hour to an hour and a half to simply get across the DFW area, so traveling to Austin (approximately 3 hours south) or Shreveport (three hours east) or Abilene (2 hours west), Houston (3 hours southeast), or Oklahoma City (3 hours north) are not considered long drives.
Hope this helps . . .
