Commuter and Non-Traditional Student Services are practically non-existent at my school. The attitude of professors is that everyone lives on campus and has their parents paying the bills. This is evident when professors expect students to come in or attend events outside of class time (but for me, this means another hour drive to campus).
Another example would be professors assigning group projects with the assumption that it is easy to "get together" outside of class with your project team members. Or, professors who refuse to accept assignments turned in via email and insist on it being submitted in person, to their office, etc., when there is otherwise no reason to come to campus (like during finals week, for example, in between days, over breaks, etc).
Parking for commuters is limited to one parking lot, very far from the main campus.
Food options are limited when it comes to anything affordable, because most students are on pre-paid meal plans anyway.
Professor policies are very often written as if intended for a group of high school aged kids, with strict rules that are very obviously intended to keep traditional aged college kids in line (for example, no "hoodies" because some students use them to sneakily listen to headphones), and discourage partying and skipping, but neglecting to recognize that some of us might have very real issues from time to time that don't fit into this little box (child illness, transportation failure for those of commuting from out of town) and there just seems to be little recognition overall that we are not ALL 18 year old students on Mommy and Daddy's dime.
Overall I would not heartily recommend someone who is a non-traditional undergrad attend Texas State unless you live in San Marcos, and only if there aren't other options. From what I understand, schools like UT Austin and UTSA have a much more diverse student body in this regard, when it comes to non-traditional students blending in well and not being ignored.
