Professor Ellie Bruecker of the University of Wisconsin at Madison completed a study of the fiscal impact of the statewide school vouchers in Wisconsin. It was published by the National Education Policy Center.

Here is the executive summary:

“Executive Summary

“In 1989, Wisconsin created the Milwaukee Parental Choice Program (MPCP), the nation’s first publicly funded private school voucher program. Over the next two decades, the Milwaukee program was steadily expanded, but remained the sole voucher program in the state. In 2011, Wisconsin added a voucher program in Racine (RPCP), and in 2013 it created the statewide Wisconsin Parental Choice Program (WPCP). Initially the statewide program was limited to 500 students and 25 schools in its first year and 1,000 students and 50 schools in its second. In 2015, the state legislature lifted the cap on participating schools and students, but limited student participation to a percentage of district enrollment—currently 2% for the 2017-18 school year. The cap will gradually increase by 1% each year until it is eliminated in 2026. Wisconsin Act 55 (2015) additionally amended the funding of the WPCP.

“Previously funding had been provided by a state general purpose revenue allocation; Act 55 generates voucher funding for incoming students by deducting the cost of a student’s voucher from the state aid allocated to the school district in which a student resides.

“As a result, the program now shifts millions of dollars from public school districts to private schools. The fiscal impact of the statewide voucher program, however, is not evenly distributed across Wisconsin’s public schools.

“This policy memo describes how the statewide Wisconsin Parental Choice Program alters the relative share of public education spending borne by the state and by local districts and estimates the differential fiscal impact of the program on Wisconsin school districts. The analysis finds that school districts could lose a substantial portion of their state aid as participation in the voucher program grows, and that small districts would be the most negatively affected.

“Currently, participation rates in the statewide program are low and students in some districts lack access to voucher schools. Nevertheless, this analysis finds that the majority of students currently eligible to participate in the program live within range of a voucher school and that, even given low participation rates, the program will have a significant effect on the fiscal support the state provides to local school districts. As more states enact or expand their voucher programs, the case of Wisconsin demonstrates that one-size-fits-all statewide programs have the potential to exacerbate funding disparities in the public system.”
