More evidence on Education Voucher Programs

From the WSJ's Political Diary:

According to the study, by Patrick Wolf of the University of Arkansas, enrollment in the [Milwaukee] program continues to grow. It doubled in size 11 times between 1997 and 2007 and grew by another 18% between 2007 and 2011. Today, more than 23,000 children participate. On average they score higher in reading and do no worse in math than similar students in Milwaukee public schools. They are also more likely to graduate from high school, enroll in college and make it through the first year -- an indication that the program is preparing students to succeed at the next level. . . .
