Discusses NY's specialized high school admissions test: What I definitely would not like to see is a defined cap based on ethnicity. The selective public high school in San Francisco, Lowell, was affected by an NAACP lawsuit that instituted a cap of 45% on any ethnicity in the school. This made the standards for admissions for Chinese Americans much higher than other groups, and a suit by Chinese Americans eventually had the strict cap lifted.
