CUSD officials talk about the "challenging demographics of our district".

Compare CUSD to East Palo Alto (Ravenswood):

White          CUSD  51.6 %         East Palo Alto  0.4 % [yeah, 11 kids]

This is what a real challenge is:

English Learners              East Palo Alto  75 %              CUSD  34 %       
Disadvantaged                 East Palo Alto  93 %              CUSD  35 %       

East Palo Alto still beats CUSD on both of the above on 'Percent At or Above Proficient'!
