New data shows, for the first time at this level of detail, how much students’ standardized test scores rise with their parents’ incomes — and how disparities start years before students sit for tests.
One-third of the children of the very richest families scored a 1300 or higher on the SAT, while less than 5 percent of middle-class students did, according to the data, from economists at Opportunity Insights, based at Harvard. Relatively few children in the poorest families scored that high; just one in five took the test at all.
The researchers matched all students’ SAT and ACT scores for 2011, 2013 and 2015 with their parents’ federal income tax records for the prior six years. Their analysis, which also included admissions and attendance records, found that children from very rich families are overrepresented at elite colleges for many reasons, including that admissions offices give them preference.
