My Guess is that you are speaking about the Stevens Ranch in Texas. Each state has its own Real Estate Board or Commission. For Texas it is called Texas Real Estate Commission (TREC). These groups have authority in a state (remember each state has its own state - level organization) to issue licenses. So if you interested in obtaining a Texas Real Estate Sales Agent license - just go to TREC's website ;=)
If you are in a different state- just google the secretary of state and search their site for real estate license.
Hope this helps, Dr. M
