Code for 'the primary standard will now be color of skin'
I wonder how many folks may decide to High School shop the decision semester for entry into one of the UC schools. If the bar is now 9% per each High School(based on what?), then what sets the 9% (ACT/SAT scores - how is the GPA of a transfer handled etc?).
Getting into one of the UC Engineering schools has such a big dollar pay off down the line that it might be worth it. They have an excellent national reputation and a low tuition given their reputation (compare them to Penn State for example).
I see one consequence of the decision - it might promote integration in ways only dreamed of by the social planners.
The question becomes is a pure meritocracy politically sustainable in subsidized education? Those folks at UC are paying $6K/yr for something that could easily be valued at $20K-$30K/yr at other places.
Obviously the effect of extending the 9% rule to each school district instead of state wide is to increase access of less qualified students statewide. I can imagine school districts in which you won’t even get 9% of the students to apply (those may be great places to shop your decision semester).
