Since its inception in Texas a baker's dozen years ago, educators look forward with every new legislative session to another round of discussion about the "top 10 percent rule," which guarantees admission to the state's public universities for these talented high school graduates. Originally passed as a way to increase enrollment of under-represented students at the state's two public national research universities, the law has drawn both praise and criticism: Praise for breaking down such barriers as test score bias or high school bias as when otherwise hard-working, ambitious, and motivated students were denied admission; criticism for blocking access by otherwise bright students not in the top 10 percent but who have exceptional test scores or top talent. Critics who argued successfully for changing the rule claim that the changes will increase access by students who previously were denied. However, those who praised the rule as it originally was written have fought changes, arguing that the very students intended to be provided access now will lose their opportunity to enroll. This article presents several myths that emerged from the 10 percent debate.
