But let us say that you were going to a community college in a fairly large city, and that your major was architecture, could you get into UT-Austin? Yes.
Will you get into their architecture program? No. Sort of.
You see, you CAN transfer to UT-Austin, but not as an architecture major. You could transfer in as an undecided major, and wait a year, and then en-roll.
Problem: you break the Design sequence. Architecture majors take Design courses every semster until they graduate. During the year you are an undecided major, you cannot take a Design course, thus delaying your graduation for one year.
<sarcasm>It gets better.<sarcasm>UT-Austin has a list of courses that they recommend you take. I'm not going to write the list in its entirety (unless I get plenty of requests for it; I will e-mail you the list of courses if you want it), but let's say that there are 62 hours worth of courses that are recommended to be taken.
Of those 62 hours, a total of 0 are architecture courses. Architecture courses DO transfer to UT-Austin, BUT they won't tell you that. There is a thing called the Texas Common Course Numbering System (TCCN), which the state assigns to all courses. For example, at San Antonio College you have to take Freshman Compostion I, referred to as ENGL 1301. ENGL 1301 is its TCCN. Other colleges and universities can call Freshman Composition ENGL 301, 103, 101A, 303K, whatever. All courses that share the same TCCN MUST transfer. It is Texas law (don't know if other states have similar laws).
Your best hope is your portfolio, which places you in a given level of Design proficiency. In fact, your portfolio really decides if you are accepted into an architecture program at all.
This is a basic introduction to the hassles of transfering to UT-Austin's architecture program. I don't know if this applies to all junior colleges, but I'll let SAC stick as the "starting point" for the transfer student. For what it is worth, I think Texas A & M is much easier to transfer to, and perhaps more friendly overall. I would place my hopes on University of Texas at Arlington, but nearly every architecture student in my classes is planning to go there. I will apply to all three universities, and most likely even more, just to maximize my opportunities.
