The era of Republican donor Betsy DeVos as Education Secretary begins with some studies that bring her outlook into question. The New York Times lays it out in Dismal Voucher Results Surprise Researchers as DeVos Era Begins…

The first results came in late 2015. Researchers examined an Indiana voucher program that had quickly grown to serve tens of thousands of students under Mike Pence, then the state’s governor. “In mathematics,” they found, “voucher students who transfer to private schools experienced significant losses in achievement.” They also saw no improvement in reading.School vouchers

The next results came a few months later, in February, when researchers published a major study of Louisiana’s voucher program. Students in the program were predominantly black and from low-income families, and they came from public schools that had received poor ratings from the state department of education, based on test scores. For private schools receiving more applicants than they could enroll, the law required that they admit students via lottery, which allowed the researchers to compare lottery winners with those who stayed in public school.

They found large negative results in both reading and math. Public elementary school students who started at the 50th percentile in math and then used a voucher to transfer to a private school dropped to the 26th percentile in a single year. Results were somewhat better in the second year, but were still well below the starting point.
