Answer:
Quota system
Explanation:
Santaro High has established a quota system because it has determined that a specific percentage of its student population must belong to a specific demographic group (racial or ethnic minorities), even if the demographic profile of the area where it is located does not correspond with the quota.
For example, the neighborhood where Santaro High is located could be 95% white, but because of the quota system it has adopted, the amount of white studends will be 80% at maximum.
