University of California San Diego (UCSD) admissions data recently unearthed by Orange County-based parent Steve Miller on Twitter suggests that despite California’s ban on affirmative action, the university is using applicants’ graduating high schools’ racial composition as a determining factor in the admissions process.

Miller found that there seemed to be no correlation between the percentage of students at a school offered admission to UCSD and the high school’s average AP score, number of AP classes, or percentage of students exceeding California Assessment of Student Performance and Progress (CAASP) standards.
