Education Secretary Betsy DeVos testifies during a June 5 hearing on Capitol Hill in Washington. Support for charter schools and private school voucher programs has gone up over the past year, with Republicans accounting for much of the increase, according to a survey published Tuesday.

WASHINGTON — Support for charter schools and private school voucher programs has gone up over the past year, with Republicans accounting for much of the increase, according to a survey published Tuesday.

The findings by Education Next, a journal published by Harvard’s Kennedy School and Stanford University, come as Education Secretary Betsy DeVos promotes alternatives to traditional public schools.

Forty-four percent of respondents in the poll conducted in May said they support the expansion of charter schools, compared to 39 percent in 2017. The gain of 5 percentage points, however, did not fully offset the drop in support from 51 percent in 2016.

When broken down according to party affiliation, 57 percent of Republicans and 36 percent of Democrats voiced support for charter schools, compared to 47 percent of Republicans and 34 percent of Democrats in 2017.

“Support is up among Republicans for various strategies to expand school choice, and the Trump administration’s embrace of those policies is a likely explanation,” said Martin West, associate professor of education at Harvard University and a co-author of the report.

Nina Rees, president of the National Alliance for Public Charter Schools, said the findings “demonstrate through the educational choices they make for their children — families want high-quality charter school options for their kids.

“Above all else, parents care that their child has access to an excellent school, and as education advocates it is our job to ensure that wish becomes a reality,” Rees added.

Robin Lake, director of the Center on Reinventing Public Education, noted that support for charters has risen mostly among Republicans.

“I hate to see an issue turn into a partisan question,” Lake said. “I don’t think that an education policy that’s designed to get better outcomes for kids should ever be a partisan issue.”

Support for publicly funded vouchers given to low-income families to help them pay tuition at private school rose from 37 percent to 42 percent over the past year.

The Education Department welcomed the results of the poll.

“The data consistently show that parents want more education options for their kids and when they are empowered with options, they like it and their kids benefit,” said press secretary Elizabeth Hill. “Education freedom is the future.”
