All the UC system schools are bound by the Prop 209 prohibition of race-based admissions policies. However, Hastings has been most successful in skirting that requirement with the LEOP program. As Javert pointed out, at least on paper, they focus on socio-economic disadvantage, which nets them a healthy number of the URM's they wouldn't be able to admit strictly based on race/ethnicity.
Very helpful, as usual Ruskie. Thanks!
