I currently attend TWU, and like it a lot. However, I do intend to transfer up after this semester.
Academically, the school is equivalent to St. Mary's and STCL. We've consistently outperformed both schools on recent Texas bar exams, so I think the school does a better job of preparing you for that.
The thing about Texas Wesleyan is its newness and lack of reputation. I would only attend if you don't mind working in Fort Worth afterwards. Last year's OCI consisted of basically mid-sized Ft Worth firms (and a smattering of Dallas ones) like Cantey Hanger, Harris Finley & Bogle, and Kelly Hart Hallman. And that's for the top 25%...anything below and you're looking at govt jobs and small shops.
It's obvious to me that TWU will continue to grow in reputation if it continues in its current direction. For now, tho, I would view it as a purely Fort Worth school.
