It sounds quite interesting to me, when I did a comparison of Texas MBAs through:
http://business-schools.startclass.com/

1. Mays Business school with a median GMAT of 648 offers an average post graduation salary of USD 93511, and the program has an acceptance rate of only 23.3%
2.Texas A&M Commerce Business School's average post graduation salary is exactly the same, but with lower medain GMAT of 460, and an acceptance of nearly 60%
3.A. R. Sanchez, Jr. School of Business admits all who applies, median GMAT is 403, still the salary is okay: USD 87169

Those are the averages of those who found work and responded to the survey. How many found work within 3 months, I wonder?

It's really hard to know what these statistics are saying, because it's not clear from that website which programs are being compared.

Mays is the only one of these schools that offers a traditional, in-class, full-time program. My guess is that the 648 GMAT score, along with the acceptance rate and salary, come from that program.

The MBAs at Commerce and Sanchez are evening programs which generally cater to older working professionals, who most likely have higher salaries (and lower GMAT scores) going into them (vs. full-time cohort programs.)
