Legacy admissions, particularly at elite colleges and universities, were thrust into the spotlight this summer when the U.S. Supreme Court effectively ended affirmative action in admissions. The ruling raised many questions, and fortunately, Harvard Kennedy School Professor David Deming and Harvard University Professor Raj Chetty were there with some important answers—having just wrapped up a 6-year study of the impact of legacy admissions at so-called “Ivy-plus” schools. Students spend years preparing to face judgment by colleges and universities as a worthy potential applicant. They strive for report cards filled with A’s in advanced placement courses. They volunteer for service projects and participate in extracurricular activities. They cram furiously high-stakes standardized tests. They do all that only to find a big question many top colleges have is effectively: “Who’s your daddy? And/or your mommy?” Using data from more than 400 colleges and universities and about three and a half million undergraduate students per year, the two economists found that legacy and other elite school admissions practices significantly favor students from wealthy families and serve a gate-keeping function to positions of power and prestige in society.
