Howdy,
I'm new to posting, but after going to Texas Online and poking around, I found this "TexasOnline was established by the Texas Department of Information Resources (DIR) and is managed by Texas NICUSA, LLC." (link:

I take that to mean Tx DIR was at some point handed "techie stuff" from various other departments, then turned around and out-sourced it or parts of it to yet another group. So, though testing may or may not have happened on the DPS side, it also may or may not have happened on the side of "Texas NICUSA, LLC." I'm happy that it is secure now, but out of general curiosity I think I'll poke around some more.
