My HP advisor said that A&M starts interviewing in mid-Aug (the earliest of the TX schools) so it's plausible that some students might have received invitations...but I'm a bit skeptical. The other TX schools start interviewing in Sept.
I received an invitation from Southwestern in mid August (only a few days after my application was transmitted and certified according to the TMDSAS site). I heard from UTMB in late August. I submitted my application on July 1st last year.
In the future, I would suggest specifically mentioning "TEXAS" in your topic lines since there are so few Texans who read this board.
I have applied to AMCAS as well, so I was including all schools. TCOM, although an DO school, is also combined with the MD schools on the same application in Texas, so they may also have similar procedures.
I got an interview letter from UT Houston about a week ago (after my TMDSAS went thru on the 26th of june...they were pretty quick). I also heard TCOM has sent out invitations as well. As for the other Texas schools, i don't expect any invitations for a few weeks.
