The Texas Ten Percent Plan (TTP) provides students in the top 10 percent of their high-school class with automatic admission to any public university in the state, including the two flagship schools, the University of Texas at Austin and Texas A&M. Texas created the policy in 1997 after a federal appellate court ruled that the state's previous affirmative-action system based on racial preferences was unconstitutional. Through the TTP Plan, the state sought to maintain diversity in its most competitive public universities in a race-neutral way. In this study, Daugherty, Martorell & McFarlin examined the effect of being eligible for automatic admission under the Texas Ten Percent Plan, and compared students in a large urban school district who just made it into their high-school's top 10 percent to students who just missed the cutoff. Results indicated that eligibility for automatic admission does appear to increase enrollment at flagship universities for students in an urban school district that sends relatively few students to college. In particular, Daugherty, Martorell & McFarlin also found these effects for underrepresented minority students. These findings are noteworthy because a key goal of the TTP Plan, and percent plans in general, is to increase access to top public universities for traditionally underserved populations.
