Here's the results with the amount of people who took the test:
---------------took-passed-failed
BAYLOR --------64 62- 2
ST. MARY'S -----26 21- 5
SOUTH TEXAS --83 65 -18
S.M.U.----------18 16-2
TEXAS TECH----23 17-6
T.S.U.----------26 20-6
T.W.U.---------40 33 -7
U OF HOUSTON-47 37-10
U OF TEXAS----37 34-3
So as you can see, the amount of students who take the test really matters and can skew these statistics a lot.
But St. Mary's still did well, but if you look at it this way, Texas Tech really didn't do that bad. They only had 6 people fail out of 23 who took the bar exam. Baylor really looks like they did a great job preparing their students, and SMU's statistic is very misleading because while only 2 people failed the bar, only 18 took the exam.
But as I said, wait until the results of the Summer bar come back, then you'll get a better idea of what the schools are really doing to prepare their students.
