Well, here are some numbers to crunch:
Effective this admissions cycle for fall 2011, Texas law dictates that UT's freshman class be composed as follows:
75% Texans auto-admitted based on class rank - top 8%*
15% Texans admitted by holistic review
10% OOS and international admitted by holistic review
*The qualifying rank for guaranteed admission will be set for each incoming class. 8% is for the class of 2011; 9% is for the class of 2012; the applicable rank for the class of 2013 will be announced no later than September 2011.
Although the applicable percentages were slightly different for last year's admission cycle (under predecessor law), you can look at the composition of the current freshman class of 2010 to get a rough idea of what kinds of numbers these formulae yield:
Texans auto-admitted based on class rank - top 10% = 5546
Texans admitted by holistic review = 989
OOS and international admitted by holistic review = 740
TOTAL enrolled class of 2010 = 7275
By design of the amended law effective Class of 2011, the OOS/international figure should remain fairly stable (10% of the freshman class). The auto-admit figure will decrease slightly, whereas the in-state holistic review figure will increase slightly.
