In 2012, the widely cited report Achievement Growth by Peterson, Eric Hanushek (Stanford) and Ludger Woessmann (University of Munich) found that student achievement gains in the U.S. fail to close the international achievement gap — the U.S. ranked 25th out of 49 countries in student test-score gains over a 14-year period. In a separate report, The Effects of School Vouchers on College Enrollment: Experimental Evidence from New York City, also by Peterson and Matthew Chingos (Brookings), found large effects for African Americans. The first systematic study of school vouchers and college enrollment also reported college enrollment increases of 24 percent for those who attended a private school with the help of a voucher. |
