After adopting a new, "holistic" approach to reviewing applications, the University of California at Los Angeles has reversed a decline in the share of black students in the freshman class it has admitted for the fall. Figures released by the university this month show that the revised admissions policy appears to have increased black students' chances of being accepted. At the same time, larger shares of white applicants, low-income applicants, and members of certain Asian-American ethnic groups were turned away. Although the new admissions policy is supposed to take into account the disadvantages that each applicant has faced, there was actually a decline in the number and share of admitted students who are the first in their families to attend college and whose households make less than $30,000 annually. Last year the university admitted 1,426 such students, or 24 percent of those who applied. This year it admitted 1,027, or about 17 percent of those who applied.
