Indiana Vouchers – Substantial, Enduring Achievement Losses
- An August 2018 report1, based on six years of longitudinal data from the nation’s largest voucher program, found that voucher students had “substantial average achievement loss” in math and no significant difference in English language arts compared to their public school peers. Public and private school students in Indiana take the same assessments, allowing “apples-to-apples comparisons of student achievement outcomes.”
- Indiana voucher students’ achievement did not improve over time; math losses remained entrenched over successive years in private schools.
Alabama Vouchers – No Change in Achievement
- A September 2018 evaluation2 of the Alabama voucher program revealed that the majority of voucher students experienced no gain or loss on standardized tests as compared to their public school peers.
- The study found that additional years in private school did not yield improvement in achievement; 73% of the 1,991 voucher students evaluated were in their third and fourth years of attendance at private voucher schools.
D.C. Vouchers – Negative Impact on Achievement
- An April 2017 report3 on the federally funded District of Columbia voucher program notes that for three consecutive cohorts of voucher recipients, all measured after their first year of attending a private voucher school, math achievement was 7.3 percentile points lower than that of those who applied to the program but were not selected to receive a voucher.
- Voucher students in elementary grades performed worse both in math and reading than their peers in traditional and charter public schools (14.7 percentile points lower in math and 9.3 points lower in reading).
Ohio EdChoice Vouchers – Persistently Lower Achievement
- According to a comprehensive evaluation4 of longitudinal data on Ohio’s EdChoice Scholarship (voucher) Program, private school voucher students “fared worse academically compared to their closely matched peers attending public schools.”
- The study finds persistently lower achievement for voucher students relative to public school peers in both math and English language arts, with the greatest disparity in math (longitudinal data, 2003-2004 through 2012-2013).
Louisiana Vouchers – Significant Achievement Losses After Four Years
- In the first two years of the Louisiana Scholarship (voucher) program, research found “strong and consistent evidence” that voucher students performed significantly worse in math after using their voucher to attend the private schools5. In the third year, math impacts ranged from significantly negative for students in early grades to statistically insignificant for other students as compared to peers in public schools6. In the fourth year, private school voucher students again declined in academic performance, experiencing “large negative effects” in math, English language arts, and science7.
- Private school voucher students scored 27 points below their public school peers in math in the first year of the voucher program, and 16 points below in the second year. In reading, voucher students trailed their public school peers by 9 points in year 1 and 8 points in year 2. At the end of their third year in private voucher schools, students still had not recovered the learning losses incurred during the first and second years of the program. After four years, students using vouchers to attend private schools continued to perform noticeably worse on state assessments than their public school peers.
Prior studies revealed little to no academic advantage:
- Long-term studies of voucher programs in Milwaukee8, the oldest school choice/voucher program in the U.S., Cleveland9,10, and the District of Columbia11 found no advantage in academic achievement for students attending private schools with vouchers.
- Milwaukee, which introduced vouchers in 1990 and by 2014 provided them to 25,000 students annually, requires its voucher students to take the same Wisconsin state tests used in the public schools. Performance results from the 2013-2014 school year showed slightly lower proficiency rates for voucher students in both math and reading as compared to their public school peers.12
- Annual studies of Florida’s tax credit (voucher) program showed negligible changes for private school voucher students. Of the 158 private voucher schools reporting more than 30 students, only 18 schools achieved statistically significant, though small, gains in reading and math from 2011 – 2014. Another 31 schools produced statistically significant losses over the three-year period. Most schools’ voucher students performed about the same as they had in previous years, neither gaining nor losing ground when compared to their peers nationally (Florida no longer reports comparative scores for in-state public school and voucher students).13
