A sample of students in Milwaukee’s private voucher schools made gains in reading in 2010-’11 that were significantly higher than those of a matched sample of peers in Milwaukee Public Schools, but math achievement remained the same last school year, according to the results of a multiyear study tracking students in both sectors.
The results of the study are being released Monday in Milwaukee as the final installment of an examination of the Milwaukee Parental Choice Program, or voucher program.
The longitudinal study – meaning it tracked the same set of students over the testing period – was conducted by the School Choice Demonstration Project, a nonpartisan research center at the University of Arkansas. The group was selected by the state to conduct a long-term study of the voucher program and its impact on Milwaukee.
Rather than looking at scores of all students, the study matched a sample of 2,727 voucher students in third through ninth grades in 2006 with an equal number of similar MPS students. The study used a complex statistical methodology based on growth models.
